The Onin War refers to a battle that started in 1467 and continued for about a decade, fought in Kyoto by the eastern army and western army of military governors. It is recorded in “Nijuikku-kata Hyojo Hikitsuke” (Box Hiragana CHI, No. 19) that Toji Temple sent its treasures and documents to the Daigo-ji Temple (醍醐寺) for shelter in September 1467, shortly after the war started, for the purpose of protecting them from the fires of war. “Nijuikku-kata” (廿一口方) refers to an in-house organization of Toji Temple in medieval times, which consisted of 21 monks. “Hikitsuke” (引付) means minutes of meetings (“Hyojo”) held by such organizations.
When Toji brought disputes to court presided by Miyoshi Nagayoshi (三好長慶) in the Sengoku period, they concluded an agreement for consultancy with Yasui Soun (安井宗運), for the purpose of enabling efficient proceedings. Therefore, Soun, as the representative of Toji visited Matsunaga Hisahide (松永久秀) many times, a vassal of Miyoshi Nagayoshi who often handled trials involving Toji.
When a dispute occurred in the Sengoku period, the Toji temple asked Miyoshi Nagayoshi (三好長慶), a powerful figure who prevailed in the Muromachi bakufu (室町幕府, Muromachi shogunate) and across the Kansai and Shikoku regions, to preside over trials.
