Yukio Mishima's 1970 Seppuku as a Final Artwork

On November 25, 1970, Yukio Mishima completed the final novel of his tetralogy "The Sea of Fertility" and then committed seppuku at the Ichigaya headquarters of the Japan Self-Defense Forces. Mishima, born Kimitake Hiraoka in Tokyo in 1925, was a celebrated Japanese author, playwright, poet, film director, and kendo master, nominated for the Nobel Prize in Literature in 1968. That same day, he symbolically occupied the headquarters with members of his private militia, the Tatenokai, taking General Kanetoshi Mashita hostage. After addressing soldiers with a speech ending in three cries of "Tenno Heika Banzai!" he performed ritual suicide. The act was meticulously planned, echoing themes from his novels and his own film performances. The seppuku involved harakiri with a tantō knife, followed by decapitation by a kaishakunin. Mishima's decapitation was botched by Masakatsu Morita, who then also committed seppuku, with Hiroyasu Koga completing both decapitations. Mishima's death is interpreted as a fusion of his four essences—writing, theater, body, and action—into a final artwork. His life and work were deeply influenced by Western and Japanese traditions, with Guido Reni's painting of Saint Sebastian being a pivotal erotic and artistic inspiration. Mishima's suicide was a protest against Japan's post-war moral decline and materialism, viewing himself as a martyr for a heroic Japan. He left a note reading "Human life is short, but I want to live forever."
