Kiri-sute gomen
Kiri-sute gomen (斬捨御免 or 切捨御免) is a Japanese expression regarding the feudal era tradition of right to strike: the right of samurai to strike and potentially kill with their sword anyone of a lower class who compromised their honour. This right was abolished in 1876 during the Meiji Restoration, when the samurai class was disenfranchised by the imperial government.
