    Yukio Mishima is considered to be one of the most important authors of the 20th century in Japan, and was nominated for the Nobel Peace Prize three separate times. In 1970, Mishima, along with four members of the Tatenokai, attempted a military coup to restore the power of the emperor. They barricaded themselves inside the office of the commander of the Tokyo headquarters of the Eastern Command of Japan's Self-Defense Forces, where they tied the commander up, and Mishima stood out onto the balcony and delivered a manifesto that he'd written to all of the soldiers below. Hoping to inspire a coup d'etat, Mishima was mocked instead by his audience. After completing his speech, he went back into the commander's office where he committed seppuku. He had carefully planned his death for over a year. His biographer suggests that the coup was merely a pretext to Mishima's suicide.
