Oda Nobunaga and the Dance Before Okehazama

At three o’clock in the morning of 19 June 1560, at Kiyosu Castle in western Owari, a 26-year-old Oda Nobunaga — outnumbered roughly ten to one by the Imagawa army that had crossed his border the day before — called for a plate of rice, stood up, and performed the Atsumori passage from the Kōwaka-mai dance. “Man’s fifty years under heaven are as nothing compared to the endless kalpa. Life, once given, must without fail come to an end.” He sang the verse, drank a cup, put on his armour, and rode out of Kiyosu with about two thousand men to attack a vanguard encampment of twenty-five thousand. By four in the afternoon Imagawa Yoshimoto’s head was in a sack on a packhorse heading back to Kiyosu, and the regional balance of power in central Japan had been permanently rewritten.

Nobunaga did not unify Japan. He was killed in Kyoto in June 1582 with roughly half the country still outside his authority, and the man who actually finished the job was his sandal-bearer. But Nobunaga is the figure the other two unifiers — Toyotomi Hideyoshi and Tokugawa Ieyasu — built their work on top of, and Japanese history remembers him as the first of the three. The reason the Atsumori dance matters is that everything you need to know about him is in it. The gamble. The self-dramatisation. The absolute refusal to be fatalistic about losing. Nobunaga knew the Imagawa odds were terrible. He went anyway, at speed, at dawn, without waiting for council. That is the pattern of the next 22 years of his life, in miniature.

Owari no Ōutsuke — the Fool of Owari

Nobunaga was born at Nagoya Castle on 23 June 1534, the second son of Oda Nobuhide — the head of the Oda Danjō-no-jō clan, a branch of the broader Oda family that served as shugo-dai (deputy military governors) of Owari Province under the shogunal appointment of the Shiba clan. “Shugo-dai of a province” sounds senior. It was not. Owari in the 1530s was a chaotic 500,000-koku province wedged between the declining Imagawa in the east, the Saitō of Mino in the north, and the Matsudaira of Mikawa (the future Tokugawa) on the southern border. The Oda clan itself was split into three rival houses — the Danjō-no-jō branch that Nobuhide led, the Yamato-no-kami at Kiyosu, and the Ise-no-kami at Iwakura — none of whom trusted the others. When Nobuhide died suddenly in March 1551, Nobunaga inherited a clan-within-a-clan-within-a-provincial-dispute that had been fighting itself for two generations. He was seventeen.

He had also spent the entirety of his teenage years cultivating what local historians called utsuke — “fool,” or “half-wit.” He wore his hair loose in a tea-whisk topknot, tied up with coloured cord. He walked through Nagoya town with his kimono open to the waist, eating persimmons and mochi off skewers in public (an unthinkable breach of samurai dignity at the time). He hung about with gangs of ashigaru and peasant boys playing rough-and-tumble games in the riverbeds. And at his father’s funeral in 1551 — an event staged with formal court solemnity at the Banshō-ji temple in Nagoya, attended by representatives of every major clan in the region — he walked up to the incense-burner, grabbed a handful of incense powder, threw it at the altar, and walked out. The attending priests and clan elders were appalled. One of them, Hirate Masahide, had been Nobunaga’s tutor and minder since childhood. Masahide bore the scene in silence. Two years later, in February 1553, he wrote Nobunaga a long remonstrance letter and committed seppuku to press the point home.

The Hirate suicide is the moment most accounts identify as the hinge. The young Nobunaga who grabbed incense at his father’s funeral in 1551 is not the same man who, by 1556, had eliminated his younger brother Nobuyuki in a succession struggle and was systematically reducing the rival Oda branches at Kiyosu and Iwakura. Masahide’s death seems to have done what his life could not — produced a Nobunaga who kept the rude energy of the utsuke years but married it to cold strategic clarity. You can see the shift in the chronicles. The Fool of Owari does not appear in any document after 1555. After 1555 there is only the Lord of Kiyosu.

The consolidation of Owari took the rest of the 1550s. Nobunaga eliminated the Iwakura branch in 1559 at the Battle of Ukino, executed his younger brother Nobuyuki after Nobuyuki tried a second rebellion in 1558, and spent the intervening years negotiating, bribing, and occasionally murdering his way through the secondary chieftains of the province. The significant thing about this period is not that he won — provincial consolidations happened constantly in Sengoku Japan — but how he did it. Nobunaga was willing to execute a brother, and willing to appear personally in ashigaru rank-and-file formations rather than in a command tent, and willing to treat military decisions as technical problems rather than questions of honour. The samurai class around him mostly still thought of war as a form of aristocratic performance. He did not. This is the gap that Okehazama would exploit.

Okehazama — the battle that should not have been won

On 12 June 1560, Imagawa Yoshimoto crossed the eastern Owari border with an army variously reported at 25,000 to 40,000 men (contemporary records disagree; the lower number is probably closer to reality). Yoshimoto was the head of the Imagawa clan of Suruga, Tōtōmi, and Mikawa — a 500,000-koku combined holding that dwarfed Nobunaga’s fragmented Owari position — and his stated objective was Kyoto. The understood objective was Owari, which he would take on the way. Within four days, the Imagawa forces had reduced two of Nobunaga’s frontier forts (Marune and Washizu) and killed their commanders. Nobunaga’s commanders at the Kiyosu war council on the night of the 18th urged a defensive posture: hold the castle, wait for the Imagawa to extend, hope for a supply collapse. Nobunaga listened, said almost nothing, and dismissed the council without orders. Then, before dawn on the 19th, he did the Atsumori dance, put on armour, and rode out with the first two thousand men he could muster.

The battle itself — covered in more detail in my dedicated piece on Okehazama — turned on two pieces of improbable luck and one piece of Nobunaga’s ruthless tactical reading. The improbable luck: a sudden heavy afternoon thunderstorm at about one in the afternoon, and the information (probably from a local peasant or merchant, probably paid for) that Yoshimoto’s command tent was at Dengaku-hazama, a ravine near the village of Okehazama where the Imagawa main force had stopped to celebrate the earlier victories with sake. The reading: Nobunaga ignored the Imagawa vanguard entirely, used the thunderstorm to mask his approach, and drove the entire Oda force directly into the ravine at Yoshimoto’s tent. The fighting lasted less than two hours. Yoshimoto was initially unconvinced the noise was an attack — he assumed it was a brawl among his own men — and by the time he drew his sword, a foot-soldier called Mōri Shinsuke had already put a spear into his side. Yoshimoto was decapitated in his own command tent. The Imagawa army, with its head-of-clan dead and its central command collapsed, disintegrated in a single afternoon.

Okehazama did three things at once. It killed the Imagawa clan as a serious regional power (they would never recover and were absorbed into the Takeda orbit within a decade). It freed the Matsudaira of Mikawa — the future Tokugawa Ieyasu — from Imagawa vassalage, and two years later in 1562 Ieyasu and Nobunaga signed the Kiyosu Alliance that would hold, without modification, for the next twenty years until Nobunaga’s death. And it made Nobunaga, overnight, the dominant power in the eastern Tōkaidō. At age 26, with a single morning’s work, he had moved from one of half a dozen squabbling mid-sized Owari warlords to a daimyō whose name was known in Kyoto.

Mino, Gifu, and Tenka Fubu — the Kyoto march

The next seven years are the Mino campaign. Nobunaga’s mother-in-law was the daughter of Saitō Dōsan, the “Viper of Mino” — covered in my separate piece on Dōsan — and Nobunaga had married Dōsan’s daughter Nōhime in 1549 in an arranged diplomatic match that had quickly turned into a genuine political partnership between the two men. Dōsan was killed by his own son Yoshitatsu in 1556, and the Saitō clan thereafter became hostile to the Oda, with the formal excuse that Nobunaga was sheltering Yoshitatsu’s rival claimants. The real reason was that Mino — the province north of Owari, centred on the Nagara River basin and the fortress of Inabayama — was the obvious next acquisition for any Owari warlord who wanted to march on Kyoto. Nobunaga spent 1561 through 1567 reducing the Saitō position piece by piece. The turning point was the August 1567 siege of Inabayama Castle, at which Nobunaga’s rapidly-promoted engineer-general Kinoshita Tōkichirō (the future Hideyoshi) built a forward position at Sunomata and enabled a final assault that brought the castle down.

Nobunaga entered Inabayama in September 1567 and did two things. He renamed the castle Gifu — referencing the Chinese city of Qishan, where the founders of the Zhou dynasty had begun their conquest — a gesture of continental-scale ambition that the Kyoto court did not miss. And he adopted a new personal seal bearing the characters tenka fubu (天下布武) — “the realm covered by military rule,” or more loosely “the whole country under one sword.” The phrase is deliberately ambiguous in the classical reading, and sixteen years of subsequent scholarship have argued over exactly what Nobunaga meant by tenka — the whole of Japan, or just the central provinces around Kyoto. My reading (and the reading most contemporary Japanese historians have landed on after the revisionist wave of the 2000s) is that Nobunaga in 1567 meant the central provinces, and expanded the ambition later as opportunities presented themselves. What matters is that the seal appears on every subsequent Nobunaga document, and nobody else was using it. The castle was covered in Gifu Castle. I have written about Gifu separately.

In September 1568 — a year after the Mino conquest — the exiled Ashikaga prince Yoshiaki came to Gifu seeking a protector. Yoshiaki’s brother, the shogun Yoshiteru, had been murdered in 1565 by the Miyoshi faction, and Yoshiaki had been trying ever since to find a daimyō willing to march on Kyoto and install him as the legitimate Ashikaga shogun. Nobunaga agreed within a month. On 18 September 1568 the combined Oda-Tokugawa army left Gifu, took the road through Ōmi, brushed aside the Rokkaku clan at Kannonji Castle, and entered Kyoto on 9 October without serious fighting. Yoshiaki was installed as the fifteenth and final Ashikaga shogun; Nobunaga was declared his kanryō (deputy-in-chief). The march from Gifu to Kyoto had taken 22 days. The Kyoto aristocracy had not seen a gaijin (outsider) warlord enter the capital with an army in three generations. They were unnerved, and they should have been.

The anti-Nobunaga coalitions — 1570 to 1573

The Kyoto installation was not the end of the war, it was the start of a much larger one. Every significant power in the central and northern provinces had an interest in Nobunaga not consolidating the Ashikaga shogunate into something that could intervene in their regional affairs. Over the next three years, three successive “encirclements” (Nobunaga hōimō) formed against him — coalitions of the Asakura of Echizen, the Azai of north Ōmi, the Takeda of Kai, the Miyoshi faction still holding territory south-west of Kyoto, the warrior-monks of Enryaku-ji on Mount Hiei, the Ikkō-ikki peasant-Buddhist leagues of the Ishiyama Hongan-ji, and (eventually) the shogun Yoshiaki himself, who turned against his own patron in 1572 when he realised Nobunaga had no intention of deferring to him on actual policy.

The 1570 Battle of Anegawa, on 30 July, was the pivot. Nobunaga and Ieyasu together defeated a combined Asakura-Azai army on a shallow river near the Ōmi-Echizen border — a confused, high-casualty engagement in which Ieyasu’s Mikawa infantry under Honda Tadakatsu (see my piece on Tadakatsu) arguably saved the Oda right wing from collapse. Anegawa did not eliminate the Asakura or the Azai, but it broke the coordination of the first anti-Nobunaga coalition. That autumn, however, Nobunaga’s brother Nobuoki was killed at the hands of the Ikkō-ikki at Ishiyama, and the second coalition began to form.

Nobunaga’s response to Enryaku-ji is the single most-discussed moment of his career, and the one where every competing biographer has to choose a side. Mount Hiei — the complex of warrior-monk temples north-east of Kyoto, headquartered at Enryaku-ji — had been an armed political faction in central Japanese politics for five hundred years. The sōhei (warrior-monks) of Hiei regularly sent armed columns into Kyoto to intimidate the court; they maintained formal military alliances with the Azai and the Asakura; and in 1571 they were actively sheltering Asakura forces retreating from Nobunaga’s pursuit. On 29 September 1571, Nobunaga moved three divisions up the eastern slope of Mount Hiei, surrounded the entire monastic complex, and burned it to the ground. Contemporary accounts give a death toll of approximately three thousand, counting monks, lay attendants, women, and children. Two hundred sixty-one buildings were destroyed. The ashes of the sanctuary were still smoking a week later when Nobunaga returned to Kyoto.

The Enryaku-ji burning is what gives Nobunaga his reputation in the popular Edo-period imagination as the “dairokuten no maō” — “demon-king of the sixth heaven.” The reputation is not wrong. But the decision was also a piece of strategic calculation that his contemporaries, once the shock wore off, quietly understood. The warrior-monk complexes had been untouchable for five centuries precisely because no one had been willing to cross the religious line. Nobunaga crossed it, and the result was that every subsequent regional warlord had to adjust their calculations. You can view his career from this date forward as one sustained campaign against any non-military political actor — temple, sect, merchant-guild, court-aristocratic — that was trying to operate as an armed faction. The 1574-1575 Nagashima campaign against the Ise Ikkō-ikki, which killed an estimated twenty thousand peasant-soldiers and non-combatants when Nobunaga burned the fortified villages; the ten-year siege of the Ishiyama Hongan-ji in Osaka; the 1574 annihilation of the Asakura and Azai clans after their second rebellion. Every one of these actions follows from the principle that Enryaku-ji established in 1571: no armed faction outside the samurai order itself has legal or religious protection. Hiei was the demonstration.

In 1573, Nobunaga deposed Yoshiaki and ended the Ashikaga shogunate formally. The shogun had assembled what would have been the third major anti-Nobunaga coalition — his 1572 call to arms reached Takeda Shingen, who marched west that winter and beat the combined Oda-Tokugawa army at Mikatagahara in January 1573. Shingen then died of illness in April while sieging a Mikawa castle, and the Takeda threat collapsed. With Shingen dead, Nobunaga turned on Yoshiaki, besieged him at Makishima Castle in July 1573, forced his surrender, and exiled him to the provinces. The Muromachi bakufu — the Ashikaga shogunate founded in 1336 — formally ended that day. Nobunaga did not replace it with his own shogunate (the emperor offered; he declined). He ruled, for the next nine years, as an uncodified central authority whose only formal title was the one the emperor gave him — Udaijin (Minister of the Right) — and whose actual power derived from the provincial armies he commanded.

Nagashino and the end of the Takeda

The Takeda under Katsuyori — Shingen’s son — rebuilt their military strength in the two years after Mikatagahara and attacked the Oda-Tokugawa borderlands again in 1575. The resulting engagement at Nagashino, on 28 June 1575, is covered in detail in my Nagashino article, so I will keep this short. The relevant point for Nobunaga’s biography is that he had spent the previous two years systematically acquiring matchlock arquebuses (tanegashima) from the Sakai and Negoro gunsmiths — reportedly three thousand of them by the time of the battle, though the figure is disputed and probably closer to a thousand in disciplined firing units. At Nagashino he deployed them behind a palisade of sharpened stakes across the narrow approach at Shitaragahara, set up rotating firing ranks, and broke six successive Takeda cavalry charges with concentrated volley fire. The Takeda cavalry — historically the finest heavy cavalry in Japan — was functionally annihilated. Katsuyori escaped. Four senior Takeda generals and perhaps ten thousand of the Takeda fighting strength did not.

Nagashino is what cemented the Nobunaga reputation for tactical innovation. The historical argument about whether Nagashino was really the “first battle of massed firearms in world history” (it wasn’t) and whether the rotating-volley tactic was actually used as Ōta Gyūichi’s Shinchō-kōki chronicle describes it (probably only partially) is interesting but secondary. What matters is the aggregate effect: a cavalry army that had been the strategic problem of central Japan for two decades was destroyed in a single afternoon by a tactical system that treated battle as an engineering discipline. Katsuyori would last seven more years as a nominal daimyō before Nobunaga’s final Kai-Shinano invasion in March 1582 reduced the Takeda to extinction, but Nagashino is where the clan’s military viability died.

Azuchi — the castle that announced the new age

In January 1576, Nobunaga began construction of Azuchi Castle on a 199-metre hill on the eastern shore of Lake Biwa, about an hour’s march north-east of Kyoto along the old Nakasendō road. Azuchi — covered in the dedicated article on Azuchi — was a genuinely new kind of structure in Japanese architecture. It was the first true tenshu (donjon) keep built in Japan: a seven-storey tower rising from a stone base, clad externally in plaster but internally in lacquered panels, painted interiors by Kanō Eitoku, gold-leafed upper floors, and a top storey built as an octagonal chamber in Chinese style with the roof painted vermilion. Contemporary Jesuit accounts — Frois in particular — describe Azuchi as the most impressive secular building in East Asia at the time. The castle was completed in 1579 after three years of uninterrupted work by a labour force estimated at thirty thousand men. Nobunaga made Azuchi his personal residence and primary seat of government in May 1579, and it remained so for the final three years of his life.

Azuchi mattered as a political statement as much as a fortress. It sat visibly on the Nakasendō road between Kyoto and the eastern provinces, so every daimyō travelling to or from the capital had to look at it. The town below the castle — Azuchi-chō — was reorganised in 1577 under a rakuichi-rakuza (“free markets, free guilds”) edict that eliminated guild monopolies, abolished customs tolls inside the domain, and offered tax-free status to merchants willing to move there. This was Nobunaga’s commercial programme in miniature: deregulate, attract capital, let the markets rather than the temple-guild combines run the distribution economy. Within a year Azuchi-chō had become one of the wealthiest non-Kyoto mercantile centres in central Japan. The broader rakuichi-rakuza principle spread outward from Azuchi to every territory Nobunaga acquired thereafter, and the Edo-period castle-town commercial system that became characteristic of Japanese urbanism through the 17th century owes its basic template to what happened in Azuchi-chō between 1577 and 1582.

Azuchi was also where Nobunaga received the Jesuits. The Portuguese Society of Jesus, in the person mainly of Luis Frois, had been petitioning for audiences with him since the late 1560s, and by the late 1570s the relationship was established and mutually useful. Nobunaga was interested in European firearms and military engineering; Frois was interested in a permissive regime under which the Jesuit mission could operate, since the Buddhist sects that had previously held religious authority in Japan were being systematically dismantled by the same man he was reporting to. In the summer of 1581 Nobunaga received an African attendant — the man later known in Japanese sources as Yasuke — whom the Jesuits had brought with them from Mozambique. Yasuke stayed at Azuchi for approximately fifteen months and became a personal attendant to Nobunaga at court, with a samurai stipend, a named sword, and a household. The exact status is disputed (the Jesuits called him an attendant; some later Japanese sources call him a kashin retainer; the details of what that meant in practice are recoverable only in glimpses) but he was with Nobunaga at Honnō-ji on the night of 21 June 1582.

Honnō-ji — the night that ended everything

By the spring of 1582 Nobunaga had essentially finished the central Japanese theatre. The Takeda were eliminated in March. The Mōri in the west were being reduced by Hideyoshi’s Chūgoku campaign. The northern Kantō was being absorbed by the Hōjō under Oda influence. The Shikoku campaign against the Chōsokabe was in preparation under Nobunaga’s third son Oda Nobutaka. And the emperor, in May 1582, formally offered Nobunaga his choice of three senior imperial posts — sei-i taishōgun (shogun), kanpaku (regent), or daijō-daijin (prime minister) — at his discretion. Nobunaga declined all three. He was going to define the new political system on his own terms, not accept one of the old ones. That was the plan for 1583.

On 21 June 1582 Nobunaga was in Kyoto preparing to move west to reinforce Hideyoshi’s Takamatsu siege. He was staying at Honnō-ji, a Hokke-sect temple in central Kyoto that he used as his informal residence when in the capital. He had with him a personal escort of approximately forty samurai, plus the Hōrō-shū elite guard, Yasuke, a few attendants, and his eleven-year-old pageboy Mori Ranmaru. Total count in the temple compound that night: perhaps a hundred fighting men. His heir Nobutada, with about two thousand, was a short distance away at the Nijō Palace.

The attack came at four in the morning of 21 June. Akechi Mitsuhide — one of Nobunaga’s most senior generals, recently assigned to reinforce the Chūgoku front — had diverted his army of approximately thirteen thousand to Kyoto on the evening of the 20th and surrounded Honnō-ji under cover of darkness. Mitsuhide reportedly pointed at the temple and said to his senior officers, “Teki wa Honnō-ji ni ari” — “The enemy is at Honnō-ji.” The troops were told only once they were in position. By dawn the temple was burning. The Oda defenders fought through the compound for perhaps an hour; Nobunaga was wounded twice, retreated to an inner room, set the room on fire himself, and committed seppuku. He was forty-eight years old. His body was never recovered from the ashes. Nobutada, alerted at the Nijō Palace, rode to attempt a rescue, was cut off by Akechi forces, fought his way back to Nijō, and committed seppuku there the same morning. Yasuke was captured alive, handed to the Jesuits by Mitsuhide on the grounds that “a dark-skinned person is not a Japanese and should not be killed,” and disappears from the Japanese written record after that date.

The question of why Akechi Mitsuhide attacked his own lord has been argued over for four and a half centuries, and I am not going to settle it here. The main theories, roughly in order of scholarly weight: personal grievance (Mitsuhide had been publicly humiliated by Nobunaga on several occasions in the preceding months, most famously over the treatment of his mother who had been handed to the Hatano clan as a hostage and then executed when Nobunaga violated the truce); political ambition (a straightforward calculation that with Nobunaga dead and Hideyoshi stuck in Bizen, Mitsuhide could seize the capital and establish his own regime); the “Imperial conspiracy” theory (that Emperor Ōgimachi, threatened by Nobunaga’s refusal of the three imperial posts, had quietly encouraged Mitsuhide to act); and the “Tokugawa inside-man” theory (that Ieyasu had prior knowledge or involvement). The documentary evidence is thin for all four, and none of the theories fully accounts for the speed with which Mitsuhide lost control of the situation after Honnō-ji. Whatever Mitsuhide’s motive was, he had thirteen days between the killing and his own death at Hideyoshi’s hands at the Battle of Yamazaki on 2 July — and he spent most of them trying to rally support that never came. Even his own son-in-law Hosokawa Tadaoki (whose mother-in-law was Akechi’s own daughter Gracia; see Hosokawa Tadaoki) refused to join him. I have written elsewhere about Akechi Mitsuhide; this is the shortest version.

The legacy — what Nobunaga actually changed

The Edo-period popular image of Nobunaga — brutal, modernising, the first of the three unifiers, the man who tried and failed — was stabilised by the 19th century and has largely stayed stable since. The revisionist historiography of the last thirty years has pushed back on the “modernising” part. Recent Japanese scholarship (Ikegami Yūko, Kanda Chisato, and others) reads Nobunaga as the final figure of the medieval order rather than the first figure of the early modern — someone who deployed familiar Sengoku instruments (cavalry, castle-towns, cadastral surveys, religious-sect management) at a scale no one else had managed, but not someone who invented a fundamentally new political form. The Edo-period innovations that posterity attributes to Nobunaga — the separation of classes, the koku registration system, the domain-level tax restructure — were all really Hideyoshi’s, and Hideyoshi was building a new order rather than extending Nobunaga’s.

What Nobunaga actually left was more specific and more limited. He demolished the armed-political role of the major Buddhist sects, which had been the longest-standing non-samurai power in the country. He established rakuichi-rakuza as a practical model for commercial deregulation, which spread through the 17th century into every castle-town in Japan. He normalised matchlock firearms as a central element of Japanese warfare rather than an auxiliary weapon, which changed the doctrinal arithmetic of every subsequent campaign. He pioneered the stone-base high-keep tenshu castle, which became the defining architectural form of the Japanese castle for the next hundred years and what every reconstructed castle you visit today is an attempt to imitate. And he created the political fact of a central-Japanese warlord who could operate at national scale, which made the Hideyoshi and Tokugawa consolidations that followed possible rather than imaginary.

On the personal side — and this is where contemporary Japanese discussion is liveliest — Nobunaga was a man who could be unusually gracious to retainers who performed, unusually cruel to those who failed, and almost entirely uninterested in ceremonies, hierarchy-for-its-own-sake, or the received opinion of anyone. He drank tea with merchants. He wore Portuguese capes and rode with Catholic priests. He promoted a peasant from sandal-bearer to the position of senior general — in a country where that had simply not been done before, ever — and made the promotion stick by deploying that peasant at Chūgoku, Tottori, Takamatsu, and the positions that mattered. He was a personal friend and alliance-partner of Tokugawa Ieyasu for twenty years, and the alliance held through periods where it should by every Sengoku convention have collapsed. He kept a number of senior retainers — Maeda Toshiie, Sassa Narimasa, Shibata Katsuie, Takenaka Hanbei (see Hanbei), Honda Tadakatsu on the Tokugawa side — whose careers he made and whose loyalty he retained largely by consistently being right about what worked. The one he could not hold was Mitsuhide.

Where to go today

Nobunaga’s physical legacy is scattered across the old Owari-Mino-Ōmi axis — a line that runs roughly west-north-west from Nagoya to the eastern shore of Lake Biwa, through the country that was the Oda heartland. You can see the significant sites in three days by train and local bus, without a rental car. Two of the obvious stops — Gifu Castle and Azuchi — are covered in dedicated articles, so I will keep those brief here and point you at them. The sites below are where you can stand in the actual ground that shaped him.

Kiyosu Castle — where the Okehazama dawn ride began

Kiyosu is the closest of the Nobunaga sites to Nagoya — twenty minutes on the JR Tōkaidō Line from Nagoya Station to Kiyosu Station, then a ten-minute walk north-west across the Gojō River. The reconstructed keep you see today is a 1989 concrete build, fairly small as reconstructions go, housing a decent local-history museum on three floors. The museum content is better than the building; the ground-floor exhibits on the 1555 clan-consolidation period and the June 1560 Okehazama war council are genuinely well-presented and include several contemporary Oda documents that you can read with the provided English summaries. The park surrounding the keep is also where the young-Nobunaga bronze statue stands — the one depicting him at approximately the moment he gave the Atsumori dance and rode out.

What I come here for, though, is not the reconstruction. The hill the castle sits on is not big, and the modern road cuts through where the outer bailey was, but the western edge of the park has a stone marker showing where the castle’s main gate faced — directly west, toward the flat rice-country that Yoshimoto’s army was coming across. Stand there on a June afternoon and you are looking at approximately the ground that twenty-five thousand Imagawa infantry were crossing on 18 June 1560. The distance from Kiyosu to the Okehazama battlefield site (about fifteen kilometres south-east near modern Midori-ku in Nagoya) is a twenty-minute local train ride; the battlefield itself is a small park with interpretive signage and a reconstruction of Yoshimoto’s tent, and it is a sensible add-on if you are already at Kiyosu. Budget half a day for the two.

Nagoya Castle — the Oda clan’s first seat

Nagoya is not technically a Nobunaga castle — the structure you visit today is a Tokugawa-period (1612) fortification built by Ieyasu to house his son Yoshinao, and the architectural vocabulary is three generations removed from Nobunaga’s own. But the site is where Nobunaga was born, in 1534, in an earlier Oda-clan fortification on approximately the same ground. The current Nagoya Castle is a 1959 reconstruction of the Tokugawa keep after the original burned in World War II bombing; it houses a museum whose middle floors cover the Oda period and include some genuinely good material on Nobuhide’s career and the 1540s Oda-clan internal politics that produced Nobunaga. The famous kinshachi — the pair of gold dolphin-like roof ornaments — are modern reproductions of the Tokugawa originals, which were themselves reportedly made from gold scavenged from Hideyoshi’s Osaka Castle after 1615. Everything is layered.

The reason to come is the Honmaru Goten — the reconstructed palace inside the inner bailey, completed in 2018 after a thirteen-year project. It is not a Nobunaga building, but the interior decorative programme — painted fusuma sliding doors, lacquered tokonoma alcoves, the overall spatial vocabulary — is the direct inheritance of what Kanō Eitoku was painting for Nobunaga at Azuchi forty years earlier. If you cannot get to Azuchi (and the Azuchi site is a set of stone foundations and a reconstruction museum rather than a surviving palace, so it is in any case partial), the Honmaru Goten at Nagoya Castle is the closest you will get to the kind of interior Nobunaga actually lived in. Nagoya Castle Station on the Meijō subway line, exit 7, ten minutes on foot. Allow half a day including the palace interior.

Honnō-ji — the temple that is not the temple

The Honnō-ji you can visit in Kyoto today is on Teramachi-dōri in Nakagyō-ku, about ten minutes on foot from Kyoto City Hall subway station. It is not on the site where Nobunaga died. After the 1582 fire, Hideyoshi reorganised central Kyoto during the Tenshō urban planning of the late 1580s and moved Honnō-ji — along with many other temples along the then-new Teramachi-dōri (literally “Temple-Town Street”) — to its present location, roughly 500 metres east of the original site. The compound you walk into today is consequently the post-relocation, post-further-fires reconstruction, not the site of the incident.

What you see is a modest compound with a main hall, a treasure house that displays a collection of Oda-period artefacts (a wakizashi reportedly owned by Nobunaga, a piece of his writing desk, fragments of roof tiles from the original Honnō-ji excavation), and a small cemetery at the back where his cenotaph stands alongside those of the Oda retainers who died with him. The treasure house is open from 9am to 4pm, entrance 500 yen at time of writing. The site of the actual 1582 Honnō-ji — the place where Nobunaga committed seppuku — is on the corner of Aburanokoji-dōri and Rokkaku-dōri in central Kyoto, marked by a modest stone stele embedded in a commercial district’s pavement. Go to both. The relocation is part of the story; so is the marker that people mostly walk past. The original spot is ten minutes’ walk from the current temple.

Kenkun Jinja — the Meiji shrine on the Kyoto hill

In 1869, as part of the early-Meiji programme of deifying historical figures who had served the imperial cause, Emperor Meiji ordered the construction of a Shintō shrine to Nobunaga on Mount Funaoka in northern Kyoto. The shrine — Kenkun Jinja, formally Takeisao Jinja — sits on the 112-metre hill north of the old imperial palace precinct, which had been, during the medieval period, the Nobunaga clan’s traditional Kyoto mustering-ground when his armies entered the capital. The Meiji-era reasoning for the choice of hill was that Nobunaga had once reportedly said he would want to be enshrined at Funaoka if anything happened to him, though the sourcing for the quote is thin and the choice was probably more about the site’s military-historical resonance than any specific Nobunaga wish.

The shrine is small and quiet — I have never been there with more than six or seven other people present — and the climb up from Kitaōji-dōri takes fifteen minutes along a stone path through forested slopes. At the top you get a view over northern Kyoto, looking south toward where Honnō-ji stands on Teramachi-dōri. The shrine itself is a simple Meiji-period structure with a small haiden (worship hall), a modest honden (main sanctuary), and a side-building selling the usual shrine amulets and omikuji fortune slips. Nobunaga’s main amulet here is one for victory in personal and professional struggles — shōbu-un — which is consistent with the man. If you are in Kyoto and you want to do the full Nobunaga circuit, this is the monument the Meiji state built to make him into an Imperial-Shintō hero. It is worth the walk if only to see what the 19th-century re-invention of the demon king of the sixth heaven looked like in Shintō-shrine architectural form. Kenkun Shrine is ten minutes by bus from Kyoto Station on the 46 route, stop at Kenkun Jinja-mae.

Ise Jingū — and the unbuilt Nobunaga monument

Ise Jingū — the Grand Shrine of Ise, in Mie Prefecture — is not a Nobunaga site in the conventional sense. It is the oldest continuously-operating Shintō shrine complex in Japan, dedicated to Amaterasu Ōmikami and rebuilt every twenty years on an adjacent site in the shikinen sengū rotation that has been running, with interruptions, for fourteen hundred years. But Nobunaga’s connection to Ise was direct and politically consequential: after the 1569 subjugation of northern Ise, he donated 3,000 koku annually to Ise Jingū from Oda revenues, restored the major shrine buildings that had been decaying during the preceding decades of civil war, and underwrote the 1585 sengū rebuilding (posthumously — Hideyoshi completed the project on Nobunaga’s behalf, three years after Honnō-ji). It is through this Oda-period patronage that Ise Jingū recovered its institutional footing after the chaotic late Muromachi centuries and began the continuous rebuilding cycle it has maintained since.

I include Ise because the Nobunaga story is incomplete without it. The usual shorthand — that Nobunaga destroyed Buddhism and promoted secular authority — misses that he simultaneously protected and strengthened the imperial Shintō establishment, the one religious institution whose legitimacy he had reasons (political, personal, and pragmatic) to maintain. The patronage was not just financial; after the 1569 campaign he personally visited Ise with a small retinue and made the formal offerings. Visit Ise if you are interested in the full shape of the Nobunaga religious policy and not just the Enryaku-ji side. The shrine is accessible via the Kintetsu Limited Express from Nagoya (90 minutes) or from Kyoto (about two hours via Osaka). Allow a full day if you want to see both the Gekū (Outer Shrine) at Ise-shi Station and the Naikū (Inner Shrine) at Uji-Yamada — the two main precincts are five kilometres apart and connected by bus.

Coming back to the dance at dawn

You can trace the Atsumori lyric — “man’s fifty years under heaven” — through the rest of Nobunaga’s life and it lands, accurately, at forty-eight. He got two years short of the verse. The dance before Okehazama was not prophecy, but it was a pattern: the willingness to go anyway, at the odds offered, at speed, without waiting for the council to agree. He burned Mount Hiei that way. He crossed the Kiso at Nagashino that way. He refused the three offered imperial titles in May 1582 that way. And he stayed at Honnō-ji with a hundred men on the night of 20 June 1582, fully aware that an attack was possible and choosing to sleep there anyway, that way. He died in a fire he set himself.

The current Honnō-ji cenotaph is about the size of a footlocker and sits in a back garden that you can walk past in thirty seconds. The original site — the corner of Aburanokoji-dōri and Rokkaku-dōri — is a stone marker embedded in commercial-district paving that you will walk past twenty times before you see it. If you are in Kyoto in mid-June, go and find both. It is the kind of weather the Imagawa came across Owari in. And the dawn comes up through the same sky he watched as a 26-year-old, on the morning he rode out to do a piece of work that no one in his war council believed he could do.
