Kosaburo Eto

was a Japanese nationalist, thinker, social activist, Japan Ground Self-Defense Force official, and member of a leading Japanese political family. He is best known for committing suicide through self-immolation as a nationalist protest in front of the Japanese Houses of Parliament.

Early life Kosaburo Eto was born in Saga prefecture on 20 April 1946, the great-grandson of Eto Shinpei, a statesman during the Meiji restoration (remembered chiefly for his role in the unsuccessful Saga Rebellion), the grandson of Eto Shinsaku, a member of the House of Representatives of Japan and close adviser of Inukai Tsuyoshi and the third son of Eto Natsuo, a member of the House of Representatives of Japan. He left Japan Ground Self-Defense Force Cadet School in Yokosuka without a diploma.

Ritual suicide and an impact on Yukio Mishima On 11 February 1969 (the National Foundation Day of Japan) aged 22, he committed suicide through self-immolation next to the Memorial Hall of Constitutional Politics, located in front of the Houses of Parliament.

Aftermath On 11 February 1975, a memorial ceremony in honour of the life of Kosaburo Eto took place at Nogi Shrine, in Akasaka, Tokyo.

Jisei no Uta (death poem) Eto's kakuseisho ended with the following jisei or death poem, a common element in Japanese ritual suicide.:

「あらあらし 空にこみとり大楠の 大御心を誰ぞ知るらん」 Under the silhouette of the big camphor tree swinging in the stiff wind against the sky, I think - who knows the Mikado's will, perhaps nobody knows it. 「かくすれば かくなるものと知りつつも やむにやまれぬ 大和魂」 I know if I take risks, it makes no difference to me, but I dare to act with a Yamato Spirit.

He wrote three kakuseisho and sent them to Shintaro Ishihara, Yukio Mishima, and Kiyoshi Oka.
