Stories of the Japanese 01354 [Muromachi/Yoshinori Period] Outbreak of the Yamato Eikyo Conflict

　Although the era name was changed to "Eikyo," the Kamakura-fu continued to use "Shocho," so I will proceed with the story while using both era names.
　Immediately after the change to the Eikyo era, a conflict known as the "Yamato Eikyo Conflict" broke out in Yamato Province.
　In Yamato Province, the Southern Court-aligned Ochi clan and the Northern Court-aligned Tsutsui clan had originally been engaged in fierce fighting. Eventually, the Northern Court side won and the Tsutsui clan came to control the key parts of Yamato Province, but the Ochi clan also maintained a certain level of influence, mainly in the southern part of the province, and the conflict continued.
　In June of the 1st year of Eikyo / 2nd year of Shocho (1429), an incident occurred in which the Northern Court-aligned local warrior, the Ido clan, killed a Southern Court-aligned monk named Tonshobo (?-1429). This was a conflict that could be called a proxy war between the Northern Court-aligned Tsutsui clan and the Southern Court-aligned Ochi clan.
　In July, the Southern Court-aligned Ochi, Toyota, and Hashio clans attacked the Tsutsui clan to avenge Tonshobo. Kofuku-ji Temple and the Shogunate advised both sides to cease fire, but neither side complied, and the fighting did not stop.
　As the fighting escalated, in February of the 2nd year of Eikyo / 3rd year of Shocho (1430), the Shogunate issued an order to Kofuku-ji Temple to suppress the Southern Court-aligned Toyota clan.
　The Shogunate also promoted appeasement policies to prevent the Southern Court from regaining momentum. They recognized the succession of the family headship to Noritomo (1423-1471), the orphaned son of Kitabatake Mitsumasa, who had rebelled and been suppressed. It is said that this was thanks to the mediation of Mansai and Akamatsu Mitsusuke, but it was likely out of fear that he would join forces with the Ochi, Toyota, and Hashio clans.
　As the situation in Yamato deteriorated, the relationship between the Shogunate and the Kamakura-fu remained tense as ever. In July, Nasu Taro, who served the Shogunate as a Kyoto O-fuji-shu, and Yuki Tomotomo of Shirakawa holed up in Nasu Kurohane Castle (Otawara City, Tochigi Prefecture) to face Mochiuji. Sasagawa Kubo Mitsunao, who wanted to support the Nasu and Yuki clans and strike a blow against the Kamakura-fu, actively requested reinforcements from the Shogunate.
　Yoshinori, who wanted to destroy Mochiuji by any means necessary, was of course eager to send reinforcements, but because many of the various daimyo were cautious, the dispatch was postponed, and Mitsunao was given the following instruction:
"Do not take any rash actions and wait for the time being."
　However, Mitsunao seemed desperate to fight, and a letter dated August 10th still exists in which he wrote something that could be considered presumptuous to the Shogunate:
"(After Mochiuji is defeated,) please leave the administration of the Kanto region to me."
　The Yamato Eikyo Conflict did not easily subside, and on August 24th of the following 3rd year of Eikyo / 4th year of Shocho (1431), the Tsutsui clan burned down Hashio Castle (Koryo Town, Nara Prefecture), and in retaliation, the Hashio clan captured the Tsutsui-aligned Horai Castle (Nara City, Nara Prefecture), causing the conflict to escalate. This war continued until the 11th year of Eikyo (1439).
