Izakuso - Izakunosho

A manor from the Kamakura and Nanboku-cho periods located in the Fukiage district of Hioki City, Kagoshima Prefecture. It was part of the Satsuma side of Shimazu Manor. Under the Ritsuryo system, it was part of Ishaku County in Satsuma Province, and in the late Heian period it became a Shimazu Manor Yosegoori (half-free), but in 1187 (Bun'ei 3), Taira Shigezumi, a member of the Satsuma Taira clan and the governor of the county, donated it to Shimazu Manor as an entire territory (free and free to enter). It was called Ishaku Manor, meaning Ishaku, an entire manor within Shimazu Manor. The head of the manor was the Konoe family, the lord was Ichijoin, and the lower rank was a descendant of Shigezumi. According to the 1197 (Kenkyu 8) "Satsuma Province Map of Fields," the land area was 200 cho. The Shimazu clan, the shugo (military governor), were appointed as land stewards, and later Hisanaga became the first of the Shimazu clan, the Ishaku clan. From the mid-Kamakura period, disputes arose between the lord (actually the lower rank) and the land stewards, and in 1324 (Shochu 1), the Shitajichubun (Dividing the Land) was carried out.

However, in 1346 (Shohei 1, Sadawa 2), the lord's position at Isakura Manor was entrusted to the local lord, Isakura Shimazu, as a military provision tax office, and became his private property, and the manor was dissolved under the manor system.

鹿児島県日置(ひおき)市吹上(ふきあげ)地区にあった鎌倉・南北朝時代の荘園。島津荘薩摩(さつま)方の一構成部分。律令(りつりょう)制下の薩摩国伊作郡の地で、平安末期に島津荘寄郡(よせごおり)（半不輸）となったが、当郡郡司で薩摩平氏一族の平重澄(しげずみ)が1187年（文治3）島津荘一円領（不輸不入）に寄進して成立。島津荘内の一円荘である伊作、の意味で伊作荘と呼称された。本所は近衛(このえ)家、領家(りょうけ)は一乗院(いちじょういん)、下司(げし)は重澄の子孫。1197年（建久8）「薩摩国図田帳(ずでんちょう)」で田地200町。地頭には守護島津氏が任命され、のち久長が伊作島津氏初代となる。鎌倉中期より領家（実際には下司）と地頭の相論が生じ、1324年（正中1）下地中分(したじちゅうぶん)をした。

　しかし1346年（正平1・貞和2）には伊作荘領家職が兵粮料所(ひょうろうりょうしょ)として地頭伊作島津氏に預けられて同氏の私領となり、荘園制上は解体された。
