Its idea was also introduced into bunkokuho (the law individual sengoku-daimyo [Japanese territorial lord in the Sengoku period] enforced in their own domain) in the Sengoku period (period of warring states) (Japan): Imagawa Kana Mokuroku (Kana List of Articles of the Imagawa) of the Imagawa clan laid down that 'those who engaged in an armed conflict were both to be executed, irrespective of the question of right or wrong,' and 'who having borne and controlled himself under the provocation... and peacefully settled the matter for the moment was judged as reasonable..., and was to be exempt from punishment' (Article 8).
こうした考え方は戦国時代(日本)の分国法にも取り入れられ、今川氏の今川仮名目録では「喧嘩におよぶ輩は理非を論ぜず双方とも死罪」「喧嘩を仕掛けられても堪忍してこらえ･･とりあえず穏便に振る舞ったことは道理にしたがったと･･して罪を免ぜられるべき」（第8条）とある。
