The policy was carried forth in the North Court (Japan), which was established after the fall of Kemmu Restoration; when a family head, a legitimate son or an adopted child inherited the family estate, or when a new chiten no kimi (the retired Emperor who organized politics) appeared, the family reign and estate were approved as a whole; consequently, the 'family' itself, including the headman's estate, was stabilized.
この方針は建武政権崩壊後に成立した北朝(日本)においても継承され、当主もしくは嫡男・猶子が家督の継承時や新たな治天の君の登場時などに家門と家領の一括安堵を受けることになり、結果的には当主の家督を含めた「家」そのものの安堵の役割を果たすことになった。
