Originally not only a shugo but also his officials and emissaries acting as his agents had been empowered to enter domestic koryo and shoen to perform their duties of Taibon Sankajo (three major tasks of peacekeeping), but the Kamakura bakufu agreed to provide special areas in which a kokushi (regional lord), ryoke (lord of the manor), honjo (proprietor or guarantor of manor), or kenmon (an influential family) were not interfered with by shugo, in order to avoid a confrontation with them.
本来、守護には大犯三箇条の義務遂行のため、本人あるいはその代理である役人・使者の国内の公領・荘園への立ち入る権利が認められていたが、鎌倉幕府は国司や領家・本所（権門）との対立を回避するために、国司や領家・本所が守護による干渉を受けない特例地域を設ける事を承認していた。
