Yatsushiro-sho

Japanese: 八代荘 - やつしろのしょう

A manor in Yatsushiro County, Kai Province. It is believed to have been established in the area of Yatsushiro-go, Yatsushiro County, which is mentioned in the Wamyō Ruijūshō. The area of the manor is unknown, but it is probably the area centered around Kumano Shrine, located north of Yatsushiro-machi, Higashi-Yatsushiro County, Yamanashi Prefecture (now Fuefuki City). It was issued by Kai no Kami Fujiwara Akito during the Kyuan era (1145-1151) and donated to the Kii Kumano Sanzan Hongu Shrine for the purpose of holding lectures. Two or three years later, it was officially established with a letter from Toba-incho. There is also a theory that the development was involved with the Yatsushiro clan, a branch of the Kai Genji clan, and Hemmi Kiyomitsu's son Nobukiyo was called Yatsushiro Yoichi. In 1162, Fujiwara Tadashige, who became Kai no Kami, ordered the abolition of the newly established manor and dispatched Nakahara Kiyohiro, the deputy governor, to Kai Province. Kiyohiro broke into the manor together with the local government official Saegusa Morimasa and others, seizing the annual tax, taking away the boji, and arresting the deity. In response to a complaint from Kumano Shrine, the Imperial Court ordered Tadashige to return the lost property, but Tadashige, Kiyohiro, and Morimasa all denied the charges. This lawsuit led to the review of the Chokan Kanbun, which discussed whether Kumano Gongen was the same as the deity worshipped at Ise Grand Shrine, as Nakahara Gyorin, a doctor of law who was ordered to review the charges against Tadashige and others, based on the Honji Suijaku theory that Kumano Gongen was the same as the deity worshipped at Ise Grand Shrine. In the end, the theory that they were not the same seemed to prevail, and Tadashige was exiled to Iyo Province. This incident of the suspension and abolition of the manor led to the decline of the Saegusa clan, a clan that had existed since ancient times, and the power of the Kai Genji Yashiro clan grew. It seems that the Yatsushiro Manor was inherited by the Ogasawara clan after the Yatsushiro Nobumasa, and in 1383 it was passed on from Ogasawara Nagamoto to his son Nagahide via Ama Jōkei, and became the hereditary property of the Ogasawara clan, the guardian of Kai.

甲斐国八代郡にあった荘園。《和名類聚抄》所載の八代郡八代郷の地に成立したとみられる。荘域は不明だが，およそ現山梨県東八代郡八代町（現・笛吹市）北の熊野神社を中心とする地域であろう。久安年間（1145年−1151年）に甲斐守藤原顕遠により立券され，紀伊熊野三山本宮に八講用途として寄進された。その２，３年後には鳥羽院庁下文を得て正式に成立した。開発には甲斐源氏の一族八代氏が関わっていたとする説もあり，逸見清光の子信清は八代余一を称していた。1162年に甲斐守となった藤原忠重は新立荘園の停廃を命じ，目代中原清弘を甲斐国に派遣。清弘は在庁官人三枝守政らとともに当荘に乱入，年貢を奪い取り，【ぼう】示(ぼうじ)を抜き取り，神人を搦め取るなどの乱暴を働いた。熊野社からの訴えにより，朝廷は忠重に損物の返還などを命じたが，忠重・清弘・守政はいずれも罪状を否定。この訴訟は，忠重らの罪名の勘申を命じられた明法博士中原業倫が，本地垂迹説により熊野権現は伊勢大神宮の祭神と同体であるとし，これを根拠に刑を判定したことから，熊野権現は伊勢大神宮の祭神と同体であるかどうかを論じる《長寛勘文》の勘申に発展した。結果は非同体説が有力となったらしく，忠重は伊予国に配流となっている。この荘園停廃事件を契機に古代以来の氏族三枝氏は没落，甲斐源氏八代氏が勢力を伸ばした。八代荘は八代信清ののち小笠原氏に継承されたらしく，1383年には小笠原長基から尼浄契を経て子息長秀に譲られており，甲斐守護小笠原氏相伝の所領となっていた。
