Ryūnosuke Akutagawa (芥川 龍之介 Akutagawa Ryūnosuke, 1 March 1892 – 24 July 1927) was a Japanese writer active in the Taishō period in Japan. He is regarded as the "Father of the Japanese short story" and Japan's premier literary award, the Akutagawa Prize, is named after him. He committed suicide at the age of 35 through an overdose of barbital.
Akutagawa wrote over 150 short stories during his brief life. The final phase of Akutagawa's literary career was marked by his deteriorating physical and mental health. Much of his work during this period is distinctly autobiographical, some even taken directly from his diaries. His works during this period include Daidōji Shinsuke no hansei ("The Early Life of Daidōji Shinsuke", 1925) and Tenkibo ("Death Register", 1926).
