His works include the novels "Confessions of a Mask" and "The Temple of the Golden Pavilion", and the autobiographical essay "Sun and Steel". His avant-garde work displayed a blending of modern and traditional aesthetics that broke cultural boundaries, with a focus on sexuality, death, and political change. Mishima was active as a nationalist and founded his own right-wing militia, the Tatenokai. In 1970, he and three other members of his militia staged an attempted "coup d'état" when they seized control of a Japanese military base and took the commander hostage, then tried and failed to inspire a coup to restore the Emperor's pre-war powers. Mishima then committed ritual suicide by "seppuku". The coup attempt became known as the "Mishima Incident".
