The Battle of the Great Buddha Hall of Tōdai-ji — Matsunaga Hisahide, the Miyoshi Triumvirate, and the Half-Year Siege that Burned Nara

From Miyoshi Clan Infighting to the Battlefield of Nara

In the second month of Eiroku 10 (1567), Miyoshi Yoshitsugu, nominal head of the Miyoshi clan, suddenly fled Takaya Castle amid conflict with the "Miyoshi Triumvirate"—Miyoshi Nagayasu, Miyoshi Masayasu, and Iwanari Tomomichi—who held real power, and took refuge with Matsunaga Hisahide, who was then holed up in Yamato in opposition to the Triumvirate. Hisahide, once a senior retainer who had wielded great power in the Kinai region under Miyoshi Nagayoshi, had clashed fiercely with the Triumvirate within the Miyoshi house after Nagayoshi's death, and had also been locked in ongoing conflict with Tsutsui Junkei over control of Yamato Province. With Yoshitsugu now joining him, Hisahide regrouped around his stronghold of Tamonzan Castle and moved toward all-out confrontation with the Triumvirate–Tsutsui alliance. The Triumvirate, for their part, secured Tsutsui Junkei as well as reinforcements from Shinohara Nagafusa from Awa and Sanuki and Ikeda Katsumasa from Settsu, massing a large army in the Nara Basin.

A Half-Year Standoff Around Tōdai-ji and Hannya-ji

On April 18, gunfire erupted between the two sides around the Nandaimon Gate of Tōdai-ji, opening the conflict. On May 2, an Iwanari Tomomichi force of roughly 10,000 from the Triumvirate side encamped within the Tōdai-ji precincts, and by mid-May the combined 8,000-strong force of Shinohara Nagafusa and Ikeda Katsumasa had entered Yamato and taken up positions at Saihō-ji. The Tamon-in Diary records the Triumvirate-Tsutsui force at over 10,000, while the Tōdai-ji Zasshūroku puts it at 20,000. For nearly half a year, the two armies faced off and skirmished around Tōdai-ji and Hannya-ji, effectively turning the temple precincts into a vast field encampment. Monks and residents of Nara were forced to flee amid the fighting, and the temple economies of Tōdai-ji and Kōfuku-ji suffered severe damage. Throughout this standoff, Hisahide's side held Tamonzan Castle while watching for an opening, while the Triumvirate forces are said to have struggled with the logistical strain of prolonged encampment.

The Great Buddha Hall in Flames: The Night Raid of October 10

After roughly half a year of standoff, late on the night of October 10, the Matsunaga–Miyoshi Yoshitsugu alliance launched a surprise attack on the Triumvirate forces encamped at Tōdai-ji. Amid the chaos of the night raid, a fire broke out at a grain storehouse within the temple grounds; the flames spread to the Hokke-dō, then along the corridors to the Great Buddha Hall itself, and by the hour of the ox (around 2 a.m.) the hall had burned to the ground. The fire caused the head of the Great Buddha (Vairocana) to collapse, and numerous structures—including the temple complex, the Nenbutsu-dō, and the Great Bodhi Hall—were reduced to ashes. The Triumvirate's forces suffered a devastating blow, with over 300 killed in battle or burned to death, and retreated toward Settsu and Yamashiro. For centuries, the fire was popularly attributed to arson ordered by Matsunaga Hisahide, but recent scholarship favors the theory that it was an accidental fire sparked by gunpowder igniting amid the chaos of the night attack—a account echoed in the Edo-period war chronicle Yamato Gunki, which records that "fire spread from gunpowder for firearms." Whatever its cause, the destruction in a single night of the Great Buddha Hall, standing since the Nara period, shocked contemporaries profoundly.

Matsunaga Hisahide's Victory, its Aftermath, and the Yamato Sword Tradition

The battle ended in victory for the Matsunaga–Miyoshi Yoshitsugu alliance; on October 21, Iimoriyama Castle, a Triumvirate stronghold, also surrendered, and Hisahide's authority over Yamato was restored. Yet the grave sin of the Great Buddha Hall's destruction sealed Hisahide's infamy, feeding the later legend that branded him a treacherous schemer guilty of "three great evils"—betraying his lord, murdering a shogun, and burning the Great Buddha Hall. Hisahide himself is remembered for the famous tea kettle "Hiragumo" and for the storied blade "Fudō Kuniyuki," which he presented to Oda Nobunaga as a token of submission—a man who skillfully wielded both tea utensils and swords as instruments of politics. Yamato Province had long been a major center of sword forging known as the "Yamato tradition," developed to meet the martial needs of the sōhei (warrior-monks) of great temples such as Tōdai-ji and Kōfuku-ji, represented by the "Five Yamato Schools": Tegai, Taima, Hōshō, Shikkake, and Senjuin. In a province where temples and armed force were inseparably intertwined, this battle—in which Tōdai-ji itself became a battlefield—stands as a symbolic end point for the temple-warrior sword culture that Yamato had long nurtured. The Great Buddha Hall was later rebuilt through the fundraising efforts of the Edo-period monk Kōkei, but the catastrophe Nara endured during the Sengoku period remains a poignant reminder of the intersection between temple life and the sword culture of the warring samurai.

The Long Rivalry Between Matsunaga Hisahide and Tsutsui Junkei over Yamato

The Battle of the Great Buddha Hall was not a sudden eruption but the culmination of a long-running struggle between Matsunaga Hisahide and Tsutsui Junkei for control of Yamato Province. Hisahide had first advanced into Yamato under Miyoshi Nagayoshi, building Tamonzan Castle and effectively bringing local lords and the powerful temple complexes of Kōfuku-ji and Tōdai-ji under his control, while Tsutsui Junkei, as the leading figure of local resistance, had clashed with him repeatedly. After Nagayoshi's death, as the conflict between the Triumvirate and Hisahide intensified, Junkei sided with the Triumvirate, seeing an opportunity to wrest control of Yamato back from Hisahide. In this sense, the Battle of the Great Buddha Hall was a composite conflict, overlaying the Miyoshi clan's internal strife in the Kinai with the regional struggle between Hisahide and Junkei for dominance over Yamato Province.

The Religious and Social Shock of the Great Buddha Hall's Destruction

That the Great Buddha Hall of Tōdai-ji, built in the Nara period at the behest of Emperor Shōmu, should be destroyed amid a conflict between warrior factions sent shockwaves through the court nobility and religious establishment of the time. The head of the fallen Great Buddha (Vairocana) remained covered by a makeshift bronze plate for nearly a century afterward, and full-scale reconstruction of the Great Buddha Hall was not achieved until the Genroku era in the mid-Edo period, through the fundraising campaigns of the monk Kōkei and the support of the Tokugawa shogunate. This prolonged neglect symbolizes the political turmoil and fiscal constraints spanning the late Sengoku through early Edo periods, and speaks to the depth of the scar the Battle of the Great Buddha Hall left on the history of Japanese Buddhism.

Matsunaga Hisahide's Later Years and Final Stand at Shigisan Castle

Having restored his authority over Yamato after the Battle of the Great Buddha Hall, Matsunaga Hisahide soon submitted to Oda Nobunaga and was confirmed in his control of the province. In Tenshō 5 (1577), however, Hisahide rose against Nobunaga a second time and holed up in his stronghold, Shigisan Castle, in what became known as the Battle of Shigisan Castle. Surrounded by Nobunaga's overwhelming forces, Hisahide is said to have refused to hand over his prized tea kettle "Hiragumo," smashing it before taking his own life—though some scholars note this episode likely contains later embellishment. Long remembered as one of the Sengoku period's most notorious schemers, guilty of the "three great evils" of betraying his lord, killing a shogun, and burning the Great Buddha Hall, Hisahide's historical reputation has undergone reassessment in recent scholarship, which increasingly favors the view that the Tōdai-ji fire was an accidental blaze rather than a deliberate act of arson.

Primary Sources on the Burning of the Great Buddha Hall

The Battle of the Great Buddha Hall and the circumstances of its destruction are recorded in detail in the Tamon-in Diary, a primary source kept by monks of Kōfuku-ji documenting the day-to-day course of the fighting, as well as in other sources such as the Tōdai-ji Zasshūroku and the Tokitsugu-kyō Ki. Cross-referencing these records preserves for us today a detailed account of the half-year course of events leading to the hall's destruction, along with the shock and bewilderment felt by contemporaries. A temporary hall was later attempted under Toyotomi Hideyori, but full reconstruction was not achieved until the mid-Edo period, through the fundraising campaigns of the monk Kōkei, finally restoring the Great Buddha Hall to the form seen today. The temple complex of Tōdai-ji that still stands in Nara preserves the memory of an era when the strife among warriors turned a great temple itself into a battlefield.
