After the Jyokyu War in the early thirteenth century, the Shinpo rippo (the regulation regarding new Jito appointments) was established to give 1 cho of kyuden per 11 cho of shoen koryo to newly appointed jito, but in actuality, there were many cases where two or even three cho of kyuden were given, strongly pushing the invasion of newly appointed jito into shoen koryo.
13世紀前半の承久の乱以降、新補地頭に対して荘園公領11町当たり1町の給田を与える新補率法が成立すると、実際には1町にとどまらず2町・3町の給田を設定する例が多く見られ、新補地頭による荘園公領侵出を強く後押しした。
