Seppuku

Seppuku (切腹 or せっぷく, "stomach- or abdomen-cutting") or harakiri (腹切り, "cutting the belly") is a form of Japanese ritual suicide by disembowelment. It was originally reserved for samurai. Part of the samurai bushido honor code, seppuku was used either voluntarily by samurai to die with honor rather than fall into the hands of their enemies (and likely suffer torture) or as a form of capital punishment for samurai who had committed serious offenses, or performed because they had brought shame to themselves. The ceremonial disembowelment, which is usually part of a more elaborate ritual and performed in front of spectators, consists of plunging a short blade, traditionally a tantō, into the abdomen and drawing the blade from left to right, slicing the abdomen open.
