Otorisou - Otori no sho

An imperial estate located in Otori County, Izumi Province (near Otori in the west of Sakai City, Osaka Prefecture). The area was originally called Otori-go. As the remains of a jori (grid-lined street) structure have been found and the Kumano Kaido road passed through the area, it is believed that development began early on. The circumstances surrounding the establishment of the estate are unknown, but it is believed to have been donated to Kitashirakawa-in, the mother of Emperor Gohorikawa, in the early 13th century, and thereafter passed down as Muromachi-in territory. In 1224 (Gannin 1), the Tashiro clan entered the area as newly appointed land stewards. They often fought with the Ryoke side over local control, but in 1311 (Ocho 1) they sought to settle the matter by dividing the land into smaller parts. However, even before the establishment of the manor, this land had been given to the Obantoneri (chief of the regent family) as a fief, and a new dispute developed between the Tashiro clan and the Obantoneri over how to treat it. From the end of the Kamakura period to the Nanboku-cho period, the Obantoneri allied with the powerful local village headmen (myoshu) and used their strength to oppose the Tashiro clan. The Tashiro clan consistently supported the Ashikaga side during the Nanboku-cho period, which gave them an advantage in the local dispute, and in the Muromachi period, they defeated the power of the imperial family and the Obantoneri and controlled the entire area.

和泉(いずみ)国大鳥郡（大阪府堺(さかい)市西部の鳳(おおとり)付近）にあった皇室領荘園。もともと大鳥郷とよばれた地。条里遺構が認められ、熊野街道も通じることから、開発は早くから進んでいたと考えられる。立荘の事情は不詳だが、13世紀初め、後堀河(ごほりかわ)天皇の母北白河院(きたしらかわいん)に寄進され、以後室町院(むろまちいん)領として伝えられたと考えられている。1224年（元仁1）田代(たしろ)氏が新補(しんぽ)地頭としてこの地に入部。現地支配をめぐって領家(りょうけ)側としばしば争ったが、1311年（応長1）下地中分(したじちゅうぶん)することで結着を図った。しかし、立荘以前からこの地には、摂関家の大番舎人(おおばんとねり)に所領が与えられていたため、その扱いをめぐって、新たに田代氏と大番舎人の争いに発展した。鎌倉時代末期から南北朝時代にかけては、大番舎人らが周辺の有力名主(みょうしゅ)と結び、実力で田代氏に対抗した。田代氏は南北朝時代には一貫して足利(あしかが)方に従ったこともあり、現地での争いを有利に導き、室町時代に入ると、皇室や大番舎人らの勢力を退け、一円支配を行った。
