Seppuku

Seppuku (切腹, lit. 'cutting [the] belly'), also called harakiri (腹切り, lit. 'abdomen/belly cutting', a native Japanese kun reading), is a form of Japanese ritualistic suicide by disembowelment. It was originally reserved for samurai in their code of honor, but was also practiced by other Japanese people during the Shōwa era (particularly officers near the end of World War II) to restore honor for themselves or for their families.

The practice dates back as far as the Heian period (794 to 1185), when it was done by samurai who were about to fall into the hands of their enemies and likely be tortured. By the time of the Meiji era (1868 to 1912), it had taken on an association with honor, and had also become a capital punishment for samurai who had committed serious offenses, sometimes involving a ritual imitation of cutting oneself (with a wooden dirk). 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 belly and drawing the blade from left to right, slicing the belly open. If the cut is deep enough, it can sever the abdominal aorta, causing death by rapid exsanguination.
