Japan Through the Ages: A Walk Through 1,200 Years of History

The same patch of central Kyoto where Emperor Kanmu laid out his new capital in 794 is where, in 1947, the post-war Constitution was promulgated under Emperor Hirohito. Twelve hundred and fifty years separate those two ceremonies, and they happened on more or less the same lawn. I find that the most useful single fact you can hold in your head about Japanese history. The institutional skin keeps changing, the location does not, and the country has been one continuous polity since the late Yamato period without anyone ever quite managing to break it.

What you call an “era” depends on which century you are standing in. The early names (Nara, Heian, Kamakura, Muromachi) are descriptive, made up by historians long after the fact and pegged to the seat of government. The later ones (Meiji onwards) are imperial regnal periods, locked tight to a specific emperor’s reign. Between 794 and 1868 the country had four imperial era names that historians actually bother to remember. In the 158 years after 1868 it has had five, because the Meiji government rewrote the rule and assigned exactly one era name per emperor.

I have written ten separate deep-dive articles on the eras that matter most for travel and culture, and this one stitches them together in a single chronological walk. By the end you should know what counts as a samurai, why the imperial line and the actual government were almost always two different things, and which three eras to anchor your next trip around. I am going to tell you my own pick at the bottom, and it is going to surprise you.

What an “era” actually is in Japan

Before 1868, era names (nengō) changed for reasons that ranged from the death of an emperor, to a comet sighting, to a particularly bad earthquake. The Heian period alone covers more than fifty separate nengō. Historians later collapsed those into the single descriptive label “Heian,” meaning “the era when the capital was Heian-kyō.” The Kamakura, Muromachi, and Edo periods follow the same logic: each name points to where the bakufu (shogun’s military government) had its headquarters at the time.

The Meiji government changed the rule with a single 1868 decree. From that point forward, one emperor would correspond to one era, the era name would change only on his death (or, since 2019, his abdication), and the era and reign would be coextensive. That is why the Meiji, Taishō, Shōwa, Heisei, and now Reiwa periods are imperial in a way that Heian and Kamakura are not.

You also need to hold two parallel governments in your head for most of the period this article covers. From 1185 to 1868, an unbroken six hundred and eighty-three years, Japan ran on a dual structure: an emperor in Kyoto who was the religious and ceremonial head of state, and a shogun (military dictator) who actually governed. The two were almost never in the same city, and on at least one famous occasion they were at war with each other. The fact that both institutions survived the period with the imperial line still intact is one of the genuinely strange feats of Japanese political history.

Heian (794 to 1185): the four hundred years that invented Japanese literature

The Heian era runs 794 to 1185, almost four full centuries, and it is the longest single stretch of Japanese history during which no foreign army crossed and no rival capital challenged. That stability gave the court the unusual privilege of getting bored. Bored aristocrats invented the kana scripts, the 31-syllable waka, the 12-layered junihitoe robe, and the most sophisticated prose fiction the world had yet seen. They also let the country drift, at the edges, toward the warrior class that would eventually swallow the court whole.

Emperor Kanmu moved the capital to Heian-kyō (modern Kyoto) in 794 because the Buddhist monasteries of Nara had become political problems. The grid plan he laid out was copied straight from Tang-dynasty Chang’an: a rectangle 4.5 km east-to-west by 5.2 km north-to-south, sliced down the middle by Suzaku Avenue at 84 metres wide. He placed the new Buddhist temples deliberately outside the city wall so they could not pour into a riot. Then he kicked off two new schools (Tendai and Shingon) on remote mountains, both far enough from court politics to stay out of imperial succession fights.

The Fujiwara clan figured out the trick early. They never claimed the imperial title for themselves. They simply made sure every emperor for two centuries running was the son of a Fujiwara mother and the husband of a Fujiwara wife. The job titles were Sesshō (regent for a child emperor) and Kampaku (regent for an adult emperor), and the system as a whole is called sekkan seiji. The system peaked with Fujiwara no Michinaga, who in 1018 had three daughters as empresses to three different emperors at the same time. He composed a poem that night that has gone down as the most arrogant line in Japanese history: “this world I think of as my world, like the full moon I think nothing is missing from it.”

The literary explosion happened because educated men wrote in Chinese while court women wrote in kana, the new phonetic scripts that let you write Japanese the way it was actually spoken. Around 1010, Murasaki Shikibu finished The Tale of Genji, which is the world’s oldest surviving full-length novel. A few rooms over, in service to a different empress, Sei Shōnagon was writing The Pillow Book. Between those two works you have most of what later Japanese aesthetics would build on for the next eight hundred years: a refined sadness about the passage of time (mono no aware), an obsessive eye for tiny perceptual details, and a willingness to skewer your colleagues in writing that would still be read a thousand years later.

The era ended with the Genpei War of 1180 to 1185, a five-year conflict between the Taira and Minamoto warrior clans that the court had been quietly arming for two centuries. The final battle at Dan-no-ura in March 1185 killed the boy emperor Antoku, dragged a sacred sword to the bottom of the Inland Sea, and put military men in charge for the first time in the country’s history. Minamoto no Yoritomo set up his bakufu in Kamakura that year, and the Heian era was over.

Kamakura (1185 to 1333): the bakufu invented, the Mongols arrive

The Kamakura era is the one that invented the institution that would define Japanese politics for the next seven centuries. Yoritomo set up his military government on the eastern coast deliberately, hundreds of kilometres from the imperial court, and made the imperial court keep its ceremonial functions while he kept the actual power. The arrangement was so successful that it survived him by 148 years, three regime changes, and two attempted Mongol invasions.

Yoritomo himself died in 1199 after falling from a horse. His widow, Hōjō Masako, took monastic vows and was nicknamed the ama-shōgun, the “nun shogun.” She was running the country from a Buddhist convent while her father and son theoretically held the formal posts. The Hōjō family, originally a minor branch of the Taira that had switched sides, ended up holding the regent’s job (shikken) for the next 130 years. Yoritomo’s actual bloodline died out within two generations.

The Mongol invasions are the part of the era foreign readers usually know. Kublai Khan sent letters demanding tribute starting in 1268. The Hōjō ignored them. In 1274 the first invasion fleet (40,000 troops, 900 ships) staged from the Korean peninsula and landed at Hakata Bay in northern Kyushu. The Japanese were technologically outclassed (the Mongols had pavise shields, exploding tetsuhō shells, and tight formations the Japanese had never seen) but a typhoon at the end of the first day’s fighting forced the fleet to put back to sea, and what was left limped home.

The 1281 invasion was much larger: 140,000 troops in 4,400 ships, the largest sea-borne invasion in human history until D-Day in 1944. The Japanese had spent the intervening seven years building a stone defensive wall across the bay (the Genkō Bōrui, partly visible today in Fukuoka), so the Mongols could not land in force. They sat at anchor for two months waiting for reinforcements that never came, and on the night of 14 August 1281 a typhoon hit the anchored fleet at full strength. About four-fifths of the Mongol force drowned in a single night. The Japanese called the wind kamikaze, “divine wind,” and the term stuck so hard it eventually got reused for suicide pilots in 1945.

The era is also when Buddhism became mass religion. Hōnen and his disciple Shinran made Pure Land devotion accessible to peasants who could not read. Eisai brought back Rinzai Zen from China in 1191; Dōgen brought back Sōtō Zen in 1227. Nichiren founded his Lotus-based school in 1253. By the end of the Kamakura era you had the four Buddhist schools that would dominate the country for the next eight centuries, all rooted in the choices Hōjō regents made about which monks to patronise.

The Kamakura bakufu finally collapsed in 1333. Emperor Go-Daigo, who had been exiled to Oki Island for an earlier rebellion, escaped by fishing boat, organised a coalition of disaffected warlords (including a former bakufu loyalist named Ashikaga Takauji), and took Kamakura by storm. The Hōjō regent and 870 of his closest retainers committed mass suicide in the Tōshō-ji temple on 4 July 1333. Go-Daigo’s own restoration lasted three years before Takauji turned on him.

Muromachi (1336 to 1573): the Ashikaga, the Pavilions, and the war that broke the country

The Muromachi era is the one most travellers know without realising it. If you have walked the gold pavilion at Kinkaku-ji or the silver pavilion at Ginkaku-ji, sat in a tea ceremony, watched a Noh play, looked at a karesansui rock garden, or arranged flowers, you have spent time in the cultural world Yoshimitsu and Yoshimasa built between roughly 1380 and 1490. The era starts with Ashikaga Takauji betraying Emperor Go-Daigo in 1336 and setting up his bakufu in the Muromachi district of Kyoto, and ends with Oda Nobunaga walking the last Ashikaga shogun out of the city in 1573.

Yoshimitsu, the third Ashikaga shogun, is the one who pulled off the unification of the Northern and Southern courts in 1392, ending fifty-six years of dual imperial succession. He also opened formal trade with Ming China, took the title “King of Japan” from the Ming emperor (a move some Japanese historians still treat as treason), and built Kinkaku-ji as his retirement villa in 1397. He died in 1408 having spent the last decade of his life inventing a hybrid status for himself, neither pure courtier nor pure shogun.

His grandson Yoshimasa, the eighth shogun, is the cultural figure of the era. He inherited the office at age eight and spent his thirties and forties presiding over a civil war (the Ōnin War) while building Ginkaku-ji as his private aesthetic retreat. The Higashiyama culture he gathered around him at the villa is where the modern Japanese tea ceremony, the karesansui dry rock garden, ikebana flower arrangement, monochrome ink painting, and shoin-zukuri residential architecture were all formalised. Sen no Rikyū was a child during Yoshimasa’s reign, but the aesthetic vocabulary he later codified was Yoshimasa’s.

The Ōnin War (1467 to 1477) is the political disaster that defines the second half of the era. It started as a succession dispute over who would be the next shogun (Yoshimasa wanted his brother, then changed his mind when his wife produced a son), and the two main daimyō houses (Hosokawa and Yamana) lined up on opposite sides. The fighting was confined almost entirely to Kyoto, lasted ten years, and burned the imperial capital to the ground twice. By the end neither side had won, the bakufu had no actual authority outside the city, and roughly 250 daimyō provinces had decided to start running their own affairs. That is the moment the Sengoku period begins.

Sengoku (1467 to 1603): the warring states and the three unifiers

The Sengoku era overlaps the late Muromachi (the Ashikaga shogunate technically existed until 1573, but it controlled almost no territory) and runs through to Tokugawa Ieyasu’s victory at Sekigahara in 1600. It is 136 years of more or less continuous civil war, fought by roughly 250 daimyō houses, with the gradual rise of three unifying figures who collectively put the country back together. The pop-culture export of the era (samurai films, video games, tourist Sengoku-themed bars) tends to flatten the politics into hero-narrative. The actual story is more interesting because it is largely about logistics.

The single most important date in the era is 23 September 1543, when a Portuguese ship blew off course in a typhoon and washed up on Tanegashima island, an islet at the south tip of Kyushu. The crew had matchlock arquebuses with them. The local lord, Tanegashima Tokitaka, bought two for an absurd sum and ordered his swordsmiths to copy them. Within ten years Japanese smiths were turning out improvements; within thirty years the country had the largest single concentration of firearms on Earth. By the Battle of Nagashino in 1575, Oda Nobunaga’s forces would deploy approximately three thousand of these rifles in the engagement that broke the Takeda cavalry.

The first of the three unifiers was Oda Nobunaga, a Owari province warlord who broke out of his small territorial base by ambushing the much larger Imagawa army at the Battle of Okehazama in 1560. He was twenty-six. Over the next twenty-two years he conquered roughly half of Japan, walked Ashikaga Yoshiaki into Kyoto in 1568 as the new shōgun’s protector, and then deposed him in 1573 when he became inconvenient. Nobunaga’s pattern was relentless: he integrated commoners into his armies as drilled riflemen, broke the political power of the Buddhist temple federations by burning Mount Hiei in 1571, and built Azuchi Castle in 1576 as the prototype for every Japanese castle that came after.

He was killed in 1582 at the Honnō-ji temple in Kyoto, in a palace coup by his own general Akechi Mitsuhide. Mitsuhide held the country for thirteen days before Toyotomi Hideyoshi, another Nobunaga general, raced back from a campaign in the west and crushed him at the Battle of Yamazaki. Mitsuhide was killed by farmers with bamboo spears as he tried to escape. Hideyoshi spent the next eight years finishing what Nobunaga had started, and by 1590 he had unified the country under a single command for the first time since 1467.

Hideyoshi’s two great projects were the famous sword hunt of 1588 (which disarmed every non-samurai in the country) and the Korean campaigns of 1592 to 1598, an attempted invasion of Ming China through the Korean peninsula that ended in a disastrous Japanese withdrawal after Admiral Yi Sun-sin annihilated the Japanese supply fleet at Hansan Island in 1592. The peasant’s son who had risen to become Imperial Regent died in 1598 with the Korean campaign collapsing around him, leaving a five-year-old heir whose council of regents immediately began betraying each other.

The third unifier was Tokugawa Ieyasu. He was a slightly older contemporary of both Nobunaga and Hideyoshi, had served them both in turn, and had spent the entire Sengoku period quietly accumulating territory in the eastern half of the country while never quite committing to a faction. He waited out Hideyoshi’s death by two years and then, on 21 October 1600, won the Battle of Sekigahara against the loyalists of the Toyotomi heir. He was sixty years old. The battle lasted six hours and decided two and a half centuries of Japanese politics in a single afternoon.

Azuchi-Momoyama (1568 to 1603): the Sengoku as a culture

The Azuchi-Momoyama era is technically a sub-period inside the Sengoku, running from Nobunaga’s entry into Kyoto in 1568 to Ieyasu’s appointment as shogun in 1603. Historians use the name because the cultural production of those thirty-five years (the gold-leaf castle interiors, the Kanō Eitoku screen paintings, the Sen no Rikyū tea aesthetic, the gold tea room, the Nanban screens recording European arrival) is so distinctive it cannot be lumped in with the rest of the Muromachi or with the Edo that followed.

Nobunaga built Azuchi Castle on the eastern shore of Lake Biwa in 1576 to 1579. Seven stories, 46 metres tall, the top three painted in gold leaf and crowned with an octagonal belvedere. Before Azuchi, Japanese castles were essentially fortified mountain camps with wooden watchtowers. After Azuchi, every castle keep you see in Japan (Himeji, Matsumoto, Kumamoto, Hikone, Kōchi) is descended from the same prototype. The original burned down in 1582, three weeks after Nobunaga’s death, but the granite stone podium is still on the hilltop above modern Azuchi station.

Kanō Eitoku is the painter who decorated both Azuchi and Hideyoshi’s Jurakudai palace in Kyoto. The interiors are gone (Azuchi burned, Jurakudai was dismantled in 1595), but the surviving Eitoku screens (Cypress Trees, the Karajishi Chinese lions) give you the visual register: gold leaf grounds, thick decisive outlines, saturated mineral pigment, no negative space. It was deliberately the opposite aesthetic to the Higashiyama monochrome ink wash that Yoshimasa had championed a century earlier.

Hideyoshi’s golden tea room is the era’s most concentrated cultural artefact. Three tatami mats, walls covered in gold leaf, pillars wrapped in gold, and originally the entire utensil set in solid gold or gilded copper. The whole thing was disassemblable, and Hideyoshi had it carted to Osaka, Kyoto, the imperial palace, and to his war camp during the Korean campaigns. The same Hideyoshi was simultaneously studying tea under Sen no Rikyū, whose preferred tea hut (Tai-an at Myōki-an, the only confirmed Rikyū structure still standing) is two mats, has a guest entrance you have to crawl through, and is 1.7 square metres total. The cultural argument inside Hideyoshi about which version of tea was right ended in 1591, when he ordered Rikyū to commit ritual suicide.

The era also produced the Nanban screens. Portuguese traders arrived from Macau starting in the 1540s, the Spanish from Manila in the 1580s, and the Dutch from Batavia in 1600. Japanese painters working in Nagasaki documented the foreign ships, the Jesuit habits, the African and Korean crewmen, and the strange clothing in painted folding screens that are still your single best visual record of the encounter. Hideyoshi’s first anti-Christian edict in 1587 was largely ignored, but his successor’s enforcement was not. The crucifixion of the Twenty-Six Martyrs at Nishizaka hill in Nagasaki on 5 February 1597 is when the era’s tolerant cosmopolitanism started to harden into the persecution that the Edo bakufu would inherit.

Edo (1603 to 1868): two hundred and sixty-eight years of peace

The Edo era is the longest unbroken stretch of peace any major civilisation has ever managed. Ieyasu took the title of shogun in 1603 and moved the bakufu’s headquarters to Edo Castle, the modern Imperial Palace site in Tokyo, while leaving the emperor in Kyoto with no political function and a fixed allowance. His grandson Iemitsu finished the system by 1640. The Tokugawa family then governed Japan with no significant internal warfare for the next 228 years.

The system depended on three controls. First was sankin-kōtai, the alternate attendance policy, which required every daimyō to spend every other year living in Edo and to leave his wife and heir there permanently as hostages. The processions of daimyō and their retinues moving back and forth on the five highways of the country (the Tōkaidō, Nakasendō, and three others) bankrupted the daimyō houses on a planned schedule and made rebellion almost impossible.

The second was sakoku, the closed-country policy, in place from roughly 1639 to 1853. Japanese citizens could not leave; foreigners could not enter; the only contact with the outside world was the Dutch trading factory on the artificial island of Dejima in Nagasaki Bay, plus limited Chinese trade through the same port and a small Korean and Ryukyuan presence in Tsushima and Satsuma. For 218 years Dejima was the only patch of Japanese soil where a European could legally stand without an execution warrant.

The third was a rigid four-class social hierarchy: samurai at the top, then peasants, then artisans, then merchants. Class was hereditary and enforced by sumptuary laws that specified what each class could wear, eat, and live in. The system was rigorously enforced for the first hundred years and then started leaking quietly from about 1700 onwards as the merchant class accumulated wealth that the formally superior samurai class did not have.

The cultural production of the era is what foreign visitors usually associate with “traditional Japan.” The ukiyo-e woodblock print (Hokusai, Hiroshige, Utamaro, Sharaku) was a popular Edo-period art form, mass-produced for the merchant class. Kabuki was an Edo invention; so was bunraku puppet theatre, the haiku as Bashō codified it, sushi as a quick fast food at street stalls, the modern tea ceremony rituals, and the entire body of “samurai” cultural products that the global market still consumes. The forty-seven rōnin’s revenge for their lord at Akō in January 1703 is the founding myth of the era’s official ethics.

The system collapsed almost overnight when Commodore Matthew Perry’s American squadron sailed into Edo Bay on 8 July 1853 with four steam warships and a letter from President Millard Fillmore. The Tokugawa had no answer to a steam-powered fleet that could move against the wind. They signed the Convention of Kanagawa in 1854 opening two ports to American trade, then the much more punitive Harris Treaty of 1858 opening five more, including Yokohama and Kobe. The bakufu’s authority broke immediately, and the next decade was a four-way fight between the shogunate, the imperial loyalists in Kyoto, the foreign powers, and the daimyō houses that wanted to restructure the country.

The last shogun, Tokugawa Yoshinobu, returned formal authority to Emperor Meiji in October 1867 in a ceremony called the Taisei Hōkan, in the Ōhiroma audience hall at Nijō Castle. Some of the same Kanō school pine paintings that had watched the room since the 1620s were still on the walls. The Boshin War of 1868 to 1869 mopped up the last Tokugawa loyalists at Toba-Fushimi and at Goryōkaku in Hokkaido, and the Edo era was over.

Meiji (1868 to 1912): the modern state assembled in forty-four years

The Meiji era is the most compressed modernisation in human history. In 1868 Japan was a late-feudal society with a four-class hierarchy, no railways, no national currency, no modern army, no constitution, no parliament, no public schooling, no industrial base, and no diplomatic standing in any European capital. By 1912, when Emperor Meiji died, it had all of those, plus an expanding empire that included Taiwan, Korea, the southern half of Sakhalin, and the entire Liaodong Peninsula, plus a navy that had just defeated Imperial Russia.

The Charter Oath of 6 April 1868, read by the sixteen-year-old Meiji emperor in front of an assembly of court nobles and former domain lords, abolished feudal Japan in five short articles. By 1869 the four-class hierarchy was gone in name; by 1871 the daimyō domains were abolished and replaced with prefectures; by 1873 universal male conscription replaced the samurai monopoly on weapons; by 1876 the wearing of swords was made illegal and samurai stipends were cancelled. The samurai class, which had been a hereditary military aristocracy for seven hundred years, was abolished by paperwork in less than a decade.

The Iwakura Mission of 1871 to 1873 sent half of the senior government on a 632-day study tour of the United States and Europe. They went to study railways, factories, parliaments, and constitutions, and to renegotiate the unequal treaties Japan had been forced into in 1858. They came back having decided to copy the Prussian military system instead of the French one Japan had been using since the late shogunate, and to draft a constitution along Prussian rather than British lines. Itō Hirobumi, who had been a young anti-foreign extremist twenty years earlier, would personally draft the constitution promulgated on 11 February 1889.

Not everyone went along quietly. The Satsuma Rebellion of 1877 was led by Saigō Takamori, the same Satsuma general who had taken Edo Castle for the imperial side a decade earlier. He had resigned over a foreign-policy dispute and gone home to Kagoshima, where his old samurai retainers convinced him to lead a rebellion. The new conscript army, drilled in modern infantry tactics and equipped with breech-loading rifles, beat his samurai cavalry at Shiroyama in September 1877. Saigō committed ritual suicide on the hill above Kagoshima Bay. The samurai class died with him.

The economic transformation was equally fast. The Tomioka Silk Mill opened in 1872 with French steam-driven reels and 800 workers (mostly daughters of impoverished samurai families) producing raw silk for export. The Shinbashi-Yokohama railway opened the same year. The Meiji state ran the model factories itself for fifteen years, then privatised them at deliberately low prices to a small handful of merchant families (Mitsubishi, Mitsui, Sumitomo, Yasuda) who became the zaibatsu industrial conglomerates. By 1900 those four houses controlled most of Japanese heavy industry.

The era ended with two wars that announced Japan as a Great Power. The First Sino-Japanese War of 1894 to 1895 took nine months and ended with the Treaty of Shimonoseki, by which China ceded Taiwan, the Liaodong Peninsula, and a large indemnity. The Russo-Japanese War of 1904 to 1905 was the larger event: an Asian power had not defeated a European power in a modern war in three centuries, and it ended at the Battle of Tsushima with the entire Russian Baltic Fleet destroyed by Admiral Tōgō Heihachirō in a single afternoon. Russia conceded southern Sakhalin, the Liaodong leasehold, and effective control of Korea.

Taishō (1912 to 1926): democracy, jazz, and the worst earthquake in Japanese history

The Taishō era is the shortest of the imperial periods (only fourteen years) and the one most non-Japanese readers know least about. It is also the era when Japan briefly tried democracy. The reigning emperor, Yoshihito, had survived childhood meningitis but with permanent neurological damage, which meant he ceremonially reigned but did not govern. Power passed from the Meiji genrō (the original architects of the modern state) to a parliamentary cabinet system that had to actually answer to the elected lower house of the Diet.

Hara Takashi became the first commoner Prime Minister of Japan in 1918, and he liked being called Heimin Saishō, the Commoner Premier. Universal male suffrage passed in 1925, expanding the electorate from 3 million to 12 million in a single legislative act. Three Tokyo dailies cleared a million in daily circulation by 1924. The early 1920s were the closest the Japanese parliamentary system got to actually being a parliamentary system before the military took over again in the 1930s.

It was also the era of the moga, the modern girls. The same Marunouchi office district that opened in 1914 for the central business of Mitsubishi capitalism started, by the early 1920s, hosting Western-style cafes, dance halls, jazz clubs, and department stores. Women cut their hair short, wore Western clothes, drank cocktails, and went out in mixed company without chaperones. Bobbed hair was specifically illegal for some prefectural government employees in 1925, and the law was promptly ignored. The cultural commentary on the moga was relentless. The class anxiety underneath it was real.

The era’s defining catastrophe was the Great Kantō Earthquake at one minute past noon on 1 September 1923. The shock itself was magnitude 7.9, but the casualties were almost all from the firestorm that followed: the kitchens of central Tokyo were lit for the midday meal, and the resulting fires merged into a self-sustaining inferno that burned for two days. About 105,000 people died in Tokyo and Yokohama. Some 1.9 million were displaced inside one September week. The fires reached temperatures hot enough to warp steel girders.

Frank Lloyd Wright’s new Imperial Hotel, which had opened that very morning, survived the quake almost intact. Wright had personally designed the H-shaped plan around the geological motion he expected, and the reflecting pool out front let his guests fight the fires that destroyed the hotels around it. He talked about that pool for the rest of his life. The hotel itself was demolished in 1968 to make room for a taller replacement, but the central wing was saved and reassembled at Meiji-Mura in Inuyama, where you can still walk through it.

The reconstruction after the quake was led by Gotō Shinpei, who had run colonial Taiwan, the South Manchuria Railway, the Home Ministry, and Tokyo city hall. He proposed a radical street-grid replan with broad radial boulevards. The city establishment voted most of it down. What you see in modern Tokyo (the grid that does not quite line up, the crooked streets, the irregular blocks) is the partial Gotō plan that survived the politics. Yoshihito died on 25 December 1926. His son Hirohito, twenty-five years old, took the throne.

Shōwa (1926 to 1989): war, occupation, and the economic miracle

The Shōwa era is the longest single imperial reign in recorded Japanese history (sixty-three years), and it includes the worst things the modern Japanese state has ever done and most of the impressive things it has ever built. I do not think you can responsibly travel in Japan, or read about it, without holding both of those facts in your head at once.

The first decade is the descent. The 1929 Wall Street crash hit Japan hard, the silk export market collapsed, and the army and navy started running their own foreign policy more or less openly from the early 1930s. The 1931 Mukden Incident, in which junior officers in the Kwantung Army staged a sabotage of a Japanese railway line and used it as pretext to invade Manchuria, was carried out without permission from Tokyo and was retroactively endorsed because the alternative was disowning a successful coup. The 1932 establishment of the puppet state of Manchukuo and the 1933 withdrawal from the League of Nations followed.

The Marco Polo Bridge incident on the night of 7 July 1937 escalated into the Second Sino-Japanese War, which lasted eight years and killed somewhere between fifteen and twenty million Chinese civilians and soldiers. The Nanjing Massacre in December 1937 is the part of the war that is still actively contested by Japanese revisionist historians, against unanimous Chinese, Korean, Western, and most mainstream Japanese scholarship. The 1941 attack on Pearl Harbor, the Bataan Death March, the Bataan and Singapore campaigns, the comfort women system, Unit 731, and the long bloody island-hopping war across the Pacific followed.

The war ended on 15 August 1945, six days after the second atomic bomb at Nagasaki. Hirohito made the surrender broadcast in archaic court Japanese that ordinary listeners reportedly found almost unintelligible, and the news anchors had to translate it into modern Japanese on the fly. The Tokyo firebombing of 10 March 1945 had killed about 100,000 people in three hours; the two atomic bombings together killed about 200,000; the Battle of Okinawa in April to June 1945 killed roughly a third of the civilian population of the island. Total Japanese war dead, military and civilian combined, ran somewhere between 2.6 and 3.1 million. The country’s industrial base was rubble.

The American occupation under General Douglas MacArthur ran from September 1945 to April 1952. MacArthur kept the imperial throne, on the basis that ruling Japan without the emperor would be impossible, and forced Hirohito to issue the Humanity Declaration on New Year’s Day 1946 renouncing the divinity that the Meiji Constitution had quietly attached to the throne. A new constitution, drafted by American officers in a week and translated into Japanese, came into force in 1947. Article 9 renounced war and prohibited Japan from maintaining a military, a clause the country has spent the seventy-eight years since trying to interpret around.

The economic miracle that followed is one of the strangest stories in twentieth-century history. From 1955 to 1973 Japanese real GDP grew at an average of 9.4 percent a year, the fastest sustained growth any major economy has ever achieved. The drivers were the same zaibatsu families that had been industrialising since 1880 (now reorganised as keiretsu), heavy state direction through the Ministry of International Trade and Industry, a guaranteed export market in the United States, and an extraordinarily disciplined labour force willing to work eighty-hour weeks for thirty years on the promise of lifetime employment.

The 1964 Tokyo Olympics were the symbolic announcement. The Tōkaidō Shinkansen opened on 1 October 1964, three weeks before the Games, and ran the 515 kilometres from Tokyo to Osaka in three hours and ten minutes, faster than any train in the world. Kenzō Tange’s Yoyogi National Gymnasium, with its suspended cable roof, was unlike any building anywhere. The Sony Walkman in 1979, the Nintendo Famicom in 1983, and Toyota’s lean-production assembly methods rewrote how the world built electronics, video games, and cars.

The Bubble economy of 1986 to 1991 was the period’s last act. Tokyo land prices peaked at the point where the grounds of the Imperial Palace were notionally worth more than the entire state of California. Hirohito died on 7 January 1989 at the age of eighty-seven. His son Akihito took the throne the same day, and the Heisei era began the day after. The bubble would burst in 1991 and take the next three decades with it.

Heisei (1989 to 2019): the lost decades and the soft-power export

The Heisei era ran from January 1989 to April 2019, almost exactly thirty years, and it is the era I have lived through more than half of. It is also the most economically anomalous in modern Japanese history. The Nikkei 225 hit its all-time high of 38,915 yen on the last trading day of 1989, eleven months into Akihito’s reign, and did not recover that level until February 2024. Japanese GDP grew at an average of 0.7 percent a year between 1992 and 2019. Wages, in nominal yen terms, were lower in 2018 than they had been in 1997.

The crash itself was sharp. Tokyo land prices fell about seventy percent between 1991 and 2003. The Bank of Japan’s response (slow, conservative, focused on protecting the banking system rather than restarting growth) is now treated as the textbook example of what not to do in an asset-bubble crash. Japan’s “Lost Decade” became “Lost Decades” in the plural, then ran into the global financial crisis of 2008, then the population started declining in absolute numbers in 2010 for the first time since the post-Edo censuses began.

Two natural disasters bracket the era. The Great Hanshin Earthquake of 17 January 1995 hit Kobe at 5:46 AM with a magnitude 6.9 shock, killed about 6,400 people, and demonstrated that the Japanese Self-Defence Forces were structurally incapable of organising a domestic disaster response inside the first twelve hours. Almost everything that has been built into Japanese earthquake response since (volunteer NGOs, mutual aid networks, building code reform) traces back to the failures visible at Kobe.

The Tōhoku Earthquake of 11 March 2011 hit at 2:46 PM with a magnitude 9.0 shock, the most powerful ever recorded in Japan. The shock killed almost no one. The tsunami it generated killed about 19,500 people across the Tōhoku coast, mostly in the next forty minutes. The Fukushima Daiichi nuclear plant lost cooling, three reactor cores melted, and the resulting evacuations displaced about 165,000 people, some permanently. Treat anyone who tells you Heisei was uneventful with mild suspicion.

The cultural export of the era is what most foreign visitors associate with modern Japan. Studio Ghibli (founded 1985, but every major film from Princess Mononoke in 1997 onward was a Heisei product) made Japanese animation an internationally recognisable form. The Pokemon games launched in 1996 and became a global multimedia empire. Haruki Murakami became the most-translated living Japanese novelist. Sushi went from an exotic foreign cuisine to a high-street takeaway in most Western capitals. Inbound tourism to Japan went from 2.6 million annual visitors in 1990 to 31.9 million in 2019, a twelvefold increase.

Akihito himself was the first emperor in Japanese history to abdicate while alive in roughly two centuries (the previous case was Emperor Kōkaku in 1817), and the abdication required a special one-time law passed by the Diet in 2017. He stepped down on 30 April 2019, his son Naruhito took the throne the next morning, and the Reiwa era began. Akihito spoke for less than five minutes in his final imperial address. The whole thing felt like the best-rehearsed punctuation mark in modern Japanese history.

A brief Reiwa coda (2019 to present)

Naruhito’s enthronement on 22 October 2019 attracted heads of state from 174 countries, more than the 1990 Heisei enthronement. Five months later the COVID-19 pandemic hit, the 2020 Tokyo Olympics were postponed by a year and held without spectators in 2021, and the inbound tourism boom that had defined late Heisei was abruptly shut off. By the time the borders reopened in late 2022, the yen had fallen to a thirty-year low against the dollar, which is why your trip to Japan in 2025 will be the cheapest international vacation you have ever taken. Reiwa is six years old at the time of writing. It is too early to write a deep article about it, and I will not pretend otherwise.

The threads that run across all the eras

You can read Japanese history as a sequence of distinct eras, which is what I have just done, or you can read it as a small set of long-running themes that surface and resurface across centuries. Here are the five threads I find most useful for travel.

The dual structure of imperial throne and military government

From 1185 to 1868, an unbroken six hundred and eighty-three years, Japan ran on two parallel governments: an emperor in Kyoto with no actual political function, and a shogun (Kamakura, then Muromachi, then Tokugawa) who governed. The arrangement only ended when the Meiji Restoration of 1868 abolished the shogunate and made the emperor the formal head of state for the first time since the Heian era. What is genuinely strange is that the imperial line itself survived all those centuries of being ceremonial: the same family, in unbroken succession, has held the throne since at least the 6th century AD. No other monarchy on Earth comes close to that.

Buddhism’s three waves

Buddhism arrived in Japan in 552 AD and went through three distinct waves of mass adoption that map almost exactly onto the eras. The Heian wave (Tendai, Shingon) was elite, monastic, and politically powerful, with the Mount Hiei monasteries serving as private armies. The Kamakura wave (Pure Land, Zen, Nichiren) made Buddhism mass religion, accessible to peasants and warriors alike, and produced the four schools that still dominate the country. The Muromachi wave was the Zen aesthetic synthesis: tea ceremony, ink painting, karesansui gardens, the cultural vocabulary that foreign visitors still associate with “traditional Japan.” Each wave was a response to the failure mode of the previous one.

Castle architecture: born 1576, abolished 1873

The Japanese castle keep, the multi-story whitewashed tower with curling roof eaves that you see at Himeji, Matsumoto, Kumamoto, and the other surviving sites, is a Sengoku invention. Before 1576 there was nothing like it; after 1576, Nobunaga’s prototype at Azuchi was copied across the country for thirty years. The 1615 Tokugawa One-Castle-Per-Domain edict froze the count at about 170 castles. The 1873 Meiji Castle Abolition Decree systematically demolished most of them. Of the originals, twelve keeps survive in original construction, and they are the subject of a separate cornerstone article on this site.

The samurai class: emergence, dominance, abolition

The samurai (originally bushi, “warriors”) emerge as a recognisable social class in the late Heian period, when the court is too refined to fight and the provincial nobility starts arming household retainers to deal with banditry and tax revolts. The Genpei War of 1180 to 1185 puts them in charge of the country. They dominate the next 683 years of Japanese politics, and their value system (loyalty, courage, ritual suicide, swordsmanship, the formal code now called bushidō) is mostly an Edo-period codification by men who had never fought a battle in their lives. The Meiji Restoration abolishes them by paperwork between 1869 and 1876. Saigō Takamori‘s 1877 rebellion is the last meaningful resistance to the abolition, and it ends with him committing ritual suicide on a hill above Kagoshima Bay.

The capital question

The political centre of Japan moved seven times in twelve centuries, and the moves are themselves a quick map of which class was in charge. Nara (710 to 794) was a Buddhist-monastic capital. Heian-kyō / Kyoto (794 to 1185) was an aristocratic capital. Kamakura (1185 to 1333) was a warrior capital. Then back to Kyoto for the Muromachi era (1336 to 1573) when the warriors and the courtiers were uneasily co-located. Edo / Tokyo (1603 to present) is a commercial-bureaucratic capital, with a brief stint of Kyoto restoration during the Boshin War of 1868 to 1869 when the imperial side relocated the emperor back south for ceremonial reasons before walking him to Tokyo permanently in March 1869.

The literary canon, written almost entirely by women in the early 1000s

Most national literatures have a male founder. English has Chaucer; Italian has Dante; Spanish has Cervantes. Japan is the conspicuous exception. The four texts that anchor the entire pre-modern literary canon (Murasaki Shikibu’s Tale of Genji, Sei Shōnagon’s Pillow Book, the anonymous Kagerō Nikki, and the anonymous Tosa Nikki written under a feminine pseudonym) are all by women, all written in kana rather than Chinese, and all dated within a forty-year window between roughly 970 and 1010. The reason is structural: kana was dismissed as a women’s script, which meant women could write in the language they actually spoke while men were grinding out treatises in stiff classical Chinese. The accident of that snobbery gave Japan the world’s first novel and the first sustained piece of confessional non-fiction in any language. It is the single biggest reason the Heian era still casts a longer cultural shadow than the seven centuries of warrior government that came after it.

The wave of foreign contact, then the wall

Japan has run two distinct experiments with openness, both ending the same way. The first was 1543 to 1639, the Sengoku and early Edo encounter with Portugal, Spain, and the Dutch: 96 years of Jesuit missions, Christian conversions running into the hundreds of thousands, the arquebus, the Korean campaigns, the Nanban screens. It ended with the 1639 sakoku closure, the 1597 Twenty-Six Martyrs, and 218 years of Dejima as the only legal contact point. The second was 1853 to the present, starting with Perry’s black ships and running through the Meiji modernisation, the colonial empire, the Pacific War, the American occupation, and the modern tourist boom. The pattern in both cases is the same: a long period of selective rejection, a sudden opening, an explosion of cultural and technological transfer, and a domestic reaction. The Reiwa-era inbound tourism backlash you can already see forming in Kyoto rentals and Mount Fuji crowd-control measures is the latest version of an argument the country has been having with itself for almost five hundred years.

What to actually visit, by era

I have written what to see in each era’s deep-dive article, but here is the condensed travel cheatsheet. Treat this as a starter list. None of these sites can be done justice in a single afternoon.

Heian sites

The Heian era‘s travel anchor is Kyoto, but the specific sites are subtle. Byōdō-in’s Phoenix Hall in Uji is the most photographed Heian-era building (it is on the back of the 10-yen coin) and it is open daily. The Kyoto Imperial Palace is a Meiji-era reconstruction of the Heian Daidairi at slightly reduced scale, and free guided tours run twice daily. The Heian Shrine in Kyoto is a 1895 five-eighths replica of the original Heian-kyō palace gates and worth thirty minutes. For literature pilgrims, the Murasaki Shikibu Park in Echizen, Fukui Prefecture, is worth the train ride.

Kamakura sites

The Kamakura era rewards a day-trip from Tokyo. The Great Buddha at Kōtoku-in (the 11.4-metre bronze) is the obvious headline. Kenchō-ji and Engaku-ji in Kita-Kamakura are the founding Rinzai Zen monasteries. Tsurugaoka Hachimangū is the bakufu’s tutelary shrine. For the Mongol invasions, the Genkō Bōrui defensive wall sections in Imazu, Fukuoka, are the underrated archaeological site of the era. None of the Kamakura era’s actual government buildings survive, but the layout of the city has not changed much.

Muromachi sites

The Muromachi era is the era of the Kyoto temple gardens, and the must-visits are Kinkaku-ji (the Golden Pavilion), Ginkaku-ji (the Silver Pavilion), Tenryū-ji in Arashiyama, and Saihō-ji (the moss garden, advance booking required). Daisen-in inside the Daitoku-ji complex is the founding karesansui dry rock garden. Tōfuku-ji’s Tsūten-kyō covered bridge is the photogenic autumn momiji shot. The Tōgudō hall at Ginkaku-ji is the founding example of shoin-zukuri residential architecture, but it is rarely open. My separate article on the country’s best gardens covers the Muromachi temple gardens in detail.

Sengoku and Azuchi-Momoyama sites

The Sengoku and Azuchi-Momoyama sites are scattered across the country. The Azuchi Castle podium is on the eastern shore of Lake Biwa, a short train ride from Kyoto, and Nobunaga’s Yakata reconstruction museum is at the modern Azuchi station. Honnō-ji’s modern site in Kyoto is a few hundred metres from the original 1582 location. Himeji Castle is the surviving Azuchi-Momoyama-style keep at full scale. The Sekigahara battlefield town has a small museum and walking trails to the principal positions. Tai-an at Myōki-an, the Sen no Rikyū tea hut, is between Kyoto and Osaka; you book ahead.

Edo sites

The Edo era has the most surviving architecture, because it is also the most recent pre-modern era. Edo Castle is now the Imperial Palace; the East Gardens are open daily and free, and the foundation stones of the original keep are still on the site. Nijō Castle in Kyoto, where the Taisei Hōkan ceremony happened, is open and the Ōhiroma audience hall has the original Kanō school painted screens. The Tōkaidō and Nakasendō highways still have walkable post-towns: Magome, Tsumago, and Narai on the Nakasendō are the easiest. The Hakone Sekisho checkpoint is the most-photographed surviving sankin-kōtai infrastructure. Nikkō Tōshō-gū is Ieyasu’s mausoleum.

Meiji sites

The Meiji era‘s landmark sites cluster in Tokyo. Meiji Jingu in Yoyogi is the imperial memorial shrine, completed in 1920. The Yokohama Akarenga (the two restored 1911 to 1913 customs warehouses on the waterfront) are the closest standing thing you can walk through to feel late-Meiji industrial Tokyo Bay. Tomioka Silk Mill in Gunma is the UNESCO-listed model factory from 1872, an hour from Tokyo by Shinkansen. The battleship Mikasa in Yokosuka is Tōgō’s flagship from Tsushima, the only pre-dreadnought preserved anywhere in the world.

Taishō sites

The Taishō era is the most architecturally ephemeral, because most of what was built in the 1910s and 1920s was destroyed in the 1923 quake or the 1945 firebombings. Tokyo Station’s Marunouchi facade, restored in 2012 to Tatsuno Kingō’s 1914 original, is the era’s headline survivor. The Imperial Hotel central wing is at Meiji-Mura in Inuyama. Marunouchi itself, the Mitsubishi office district, still has a few of the original Conder-style brick offices, although most of what you see is later concrete clones. Yasukuni Shrine and the Yūshūkan Museum are the politically loaded sites of the era’s transition into early Shōwa militarism.

Shōwa sites

The Shōwa era‘s sites split between memorial and triumphalist. The memorials are the heavy ones: the Hiroshima Genbaku Dome and the Peace Memorial Park, the Nagasaki Atomic Bomb Hypocenter and Peace Park, the Okinawa Peace Memorial Park, and the Tokyo Air Raid Memorial Hall in Sumida. The triumphalist ones are the 1964 Olympic-era buildings that still anchor central Tokyo: Tange’s Yoyogi Gymnasium, the original Tōkaidō Shinkansen route, the Tokyo Tower (1958). Akihabara’s electronics market dates to the early postwar black market, and the Mishima Yukio balcony at Ichigaya is still in use as a Self-Defence Forces facility.

Heisei sites

The Heisei era‘s travel sites are largely what you already know as “modern Tokyo”: the Skytree (2012), Roppongi Hills (2003), Shibuya Scramble Crossing as it currently exists, the Ghibli Museum (2001), and the various Pokemon Centres. The Kobe Luminarie runs for two weeks every December as the Hanshin earthquake memorial. The Tōhoku coast still has a few preserved tsunami-damage sites, like the Iwate Tsunami Memorial Museum at Rikuzentakata, although most of the visible damage has been cleared and rebuilt.

Cross-cutting cornerstones

For experiences that cut across multiple eras, three more pages on this site are the deep dives. Japan’s greatest gardens covers the Muromachi temple gardens, the Edo daimyō stroll gardens, and the Meiji-Taishō Western-influenced ones. Japan’s greatest festivals covers the Heian-era court festivals, the Edo merchant-class neighbourhood festivals, and the modern Shōwa-era invented ones. The tea ceremony is the cultural thread that runs from Yoshimasa’s Higashiyama coterie in the 1480s to the modern schools in Kyoto today.

My pick of three eras to anchor a trip around

If you have one trip to Japan and want to organise it historically rather than geographically, I would not pick the obvious three (Heian, Edo, Meiji). The obvious three are what guidebooks default to because the surviving architecture is photogenic. The eras that actually reward sustained travel attention are different.

My pick is Kamakura, Azuchi-Momoyama, and Taishō. Here is why.

Kamakura is the era most travellers underestimate, because the city itself is a day-trip suburb of Tokyo and the surviving buildings are mostly Zen temples that look superficially like every other temple in Japan. What you actually get from a Kamakura-focused trip is the founding of the institution that defined the next seven centuries: the bakufu, the warrior-government, the parallel-state structure that made Japan unique among world monarchies. You also get the Mongol invasion sites in northern Kyushu (the Genkō Bōrui defensive wall is genuinely under-visited) and the Kenchō-ji and Engaku-ji Zen monasteries that introduced the cultural vocabulary that would dominate the country for the next 800 years. Three days in Kamakura, two days in Fukuoka, two days at Mount Kōya: that is your founding-of-medieval-Japan trip.

Azuchi-Momoyama is my second pick because the era is so concentrated and so visual. Thirty-five years, but those thirty-five years invented Japanese castle architecture, the gold-leaf screen aesthetic, the modern tea ceremony, the Nanban screens, and the political infrastructure that the next 268 years of Tokugawa peace would run on. You can do this era as a Kyoto-and-around itinerary: the Azuchi Castle podium on Lake Biwa, the Daigo-ji and Sanbō-in for Hideyoshi’s hanami garden, Tai-an at Myōki-an for Rikyū’s tea hut, the Sekigahara battlefield, Himeji Castle as the surviving Azuchi-style keep, and the 26 Martyrs Memorial in Nagasaki for the dark side of the era. A week. Densest cultural week in Japanese history.

Taishō is my contrarian third pick. It is the era I have just told you has the least surviving architecture, because most of it burned in 1923 or 1945. So why? Because the era’s emotional geography is what foreign visitors most reliably miss in modern Tokyo. The 1923 Kantō Earthquake is the event that explains the layout of central Tokyo today: the Gotō street plan that did not quite get built, the broad avenues like Shōwa-dōri, the irregular grid, the strange survival of pockets of pre-quake architecture in places like Yanaka. You can walk Taishō Tokyo in a single long day: Tokyo Station Marunouchi facade, the Akarenga warehouses in Yokohama, the Marunouchi office district, Meiji-Mura in Inuyama for the Imperial Hotel survivor, the Yokohama foreign settlement remnants in Yamate. The whole trip is four days and it changes how you read the city after.

The reason I would not pick Heian for a primary anchor is that the surviving Heian architecture is genuinely thin. Byōdō-in, the Imperial Palace reconstruction, a handful of temples in Uji and Kyoto: that is the list. You cannot make a week’s worth of trip from it. Heian rewards reading more than it rewards travel. The reason I would not pick Edo is that the era is so ambient in modern Japan that trying to focus a trip on it produces a kind of museum-piece itinerary (Nijō Castle, Hakone Sekisho, the Nakasendō) without the connective tissue that would make it cohere. The reason I would not pick Meiji is that the era’s architecture is mostly Western-imitative, which is interesting historically but visually less rewarding than what came before or after.

The opening, again

I started by telling you that the same patch of central Kyoto where Emperor Kanmu laid out his new capital in 794 is where the post-war Constitution was promulgated under Emperor Hirohito in 1947. The full distance between those two events is twelve hundred and fifty-three years. The institutional skin in 1947 was nothing like the institutional skin in 794. The Buddhist monasteries Kanmu had been running from were now tax-exempt charitable corporations. The aristocratic class he had built the city for was abolished in 1869 and existed in 1947 only as a memory. The shogun, who had not existed in 794 and would not exist for another 391 years, had been gone for 79 years by 1947.

And yet the location was the same lawn. The imperial line was the same family. The era name had changed nine times in twelve hundred years, and you could still walk from the gate of the Heian-jingu replica to the office where the post-war Constitution was signed in about an hour, on foot, through streets that still lay roughly on Kanmu’s grid. That is what I mean when I say Japan has been one continuous polity for fifteen hundred years. The era names change, the location does not, and the country has somehow always been the same country underneath.

If you take one thing away from this article, take that. If you take two, take that and the Mōko Shūrai Ekotoba scroll at the top. The country in that picture, the samurai charging at exploding Mongol shells, is the same country you will walk through next month in Tokyo. The era in the middle is just where you happen to be standing in time.
