"Harakiri. Also known as disemboweling yourself. Seppuku was honorable, ritual suicide typically practiced by samurai. Not only does it require enormous balls of steel, but also a steady, skilled hand, as the samurai plunged the sword into his own stomach, then made a deep, horizontal cut. Traditionally, a second swordsman was present to decapitate the samurai, preventing prolonged suffering.
In 1970, famous Japanese author Yukio Mishima tried to instigate a military coup. When he failed, he committed seppuku, but one of his followers, Morita, failed to decapitate him after four tries. Which is really awful. So another dude had to step in and finish the job. Ashamed of his failure, Morita too committed seppuku."
