About Kenji Hatanaka
Lived 1912 – 1945 (aged 33). Kenji Hatanaka was a Japanese military personnel.
Major was a Japanese military officer and one of the chief conspirators in the Kyūjō incident, a plot to seize the Imperial Palace and to prevent the broadcast of Emperor Hirohito's surrender speech announcing the end of World War II.
Military career Hatanaka served in the Military Affairs Section of the Japanese Ministry of War at the end of World War II. As one of the leaders of a group of Japanese officers determined to prevent the acceptance of the Potsdam Declaration and therefore the surrender of Japan, Hatanaka attempted a coup d'état on 14–15 August 1945. Failing to obtain the support of the War Minister, General Korechika Anami, Hatanaka organised a number of other officers and succeeded in occupying the Imperial Palace and Imperial Household Ministry.
Still needing high-level support for his cause, he tried to enlist Lieutenant General Takeshi Mori, commander of the 1st Imperial Guard Division. Mori was non-committal and a frustrated Hatanaka shot and killed him. Hatanaka and his men then spent several hours searching for the recording that had been made of the Emperor's speech announcing the surrender of Japan, and which was meant for public broadcast. When he failed to locate the recordings, he occupied the NHK Building in an attempt to prevent the speech from being broadcast. However, still without high level support and the recordings, Hatanaka abandoned his coup after receiving direct orders to do so from Eastern District Army Headquarters.
Following the failure of the coup, Hatanaka traveled to the plaza fronting the Imperial Palace. Along with his fellow conspirator, Lieutenant Colonel Jirō Shiizaki, he shot himself. In Hatanaka's pocket his short death poem was found:
In popular culture In the 1967 film Japan's Longest Day, Hatanaka was portrayed by actor Toshio Kurosawa In the 2015 film The Emperor in August, Hatanaka was portrayed by actor Tori Matsuzaka
