Yukio Mishima is the pen name of Kimitake Hiraoka , a Japanese author, poet, playwright, actor, model, film director, founder of the Tatenokai, and nationalist. Mishima is considered one of the most important Japanese authors of the 20th century. He was considered for the Nobel Prize in Literature in 1968, but the award went to his countryman Yasunari Kawabata. 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.
