Seppuku is a ritual form of suicide known more popularly as hari kari. It is a form of death which is concerned with notions of honor. It dates from the ancient samurai who feared dishonor worse than death. In their eyes death by their own hand was preferable to being humiliated by another. Yukio Mishima had often written about seppuku, suicide, and early death and he had told many people that he wished to die young. He had told his friends that when "Sea of Fertility" his four volume work,was completed, he wanted to die. He said that work on the four novels had drained him and that he felt empty. Seppuku is a theme in the book "Runaway Horses" which is the second book of the "Sea of Fertility" novels ,as well as being a recurring theme in some of his short stories.
