Attempted Coup d'état (February 26 Incident)
The February 26 incident was an attempted coup d'état in Japan, from February 26 to 29, 1936, carried out by 1,483 troops of the Imperial Japanese army who believed that those around Emperor Hirohito were morally corrupt. Several leading politicians were killed, and the center of Tokyo was briefly occupied by the rebelling troops. The coup, however, was a failure, being rejected by the strong will of Emperor Hirohito.

Seicho Matsumoto and Kiyohara
Seicho Matsumoto (松本 清張, Matsumoto Seicho) was one of the influential writers of the history of modern Japan as well as mysterious novels. In his Showa Shi Hakkutsu 『昭和史発掘』,Matsumoto cited what Yasuhira Kiyohara later revealed in 1986, in characterizing the Incident, that Kiyohara led his group of soldiers to the front of the Imperial Palace without any machine guns or weapons. Matsumoto saw in this fact that they were so immature and misunderstood Emperor Hirohito. Kiyohara said in a round-table discussion that "it was our program that we enter the Palace with the permission of Emperor Hirohito through Military Officer General to his Majesty Honjo. However, Emperor Hirohito was very furious at our coup d'état."

Konpaku
He wrote a book titled Konpaku in which he describes the Coup and Chizuko Mifune, a younger sister of his mother.
