  • Prince Naruhiko Higashikuni entered the world on the 3rd of December 1887 in Kyoto. He was the ninth son of Prince Kuni Asahiko and court lady Terao Utako. His father descended from Prince Fushimi Kuniie, the twentieth head of the Fushimi-no-miya branch. This cadet line stood as the oldest of the sesshu shinnōke branches. Members of this family could become emperor if a direct heir failed to exist. The young prince grew up within these ancient imperial structures. Emperor Meiji granted him the title Higashikuni-no-miya on the 3rd of November 1906. Permission followed for him to start a new branch of the imperial family. He married Toshiko, Princess Yasu, on the 18th of May 1915. She was the ninth daughter of Emperor Meiji. The couple had four sons together.

  • Prince Higashikuni studied military tactics at the École Spéciale Militaire de Saint-Cyr in Paris. He also attended the École Polytechnique during his time abroad. These studies spanned from 1920 to 1926. While living in France, he became known as somewhat of a rebel. His behavior scandalized the Imperial Court back home. He maintained a French mistress while stationed there. Fast cars and high living defined his daily routine. He left his wife and children behind in Japan. The death of his second son did not prompt his return to Tokyo. The Imperial Household Ministry dispatched a chamberlain to Paris to collect him. He returned to Japan in 1926 after completing his education. Upon arrival, he was promoted to colonel in that same year.

  • He graduated from the Imperial Japanese Army Academy as a second lieutenant in 1908. Promotion to lieutenant followed in 1910. Captain rank arrived in 1913. Graduation from the Army War College occurred in 1914. Commissioned as captain in the 29th Infantry Brigade, he rose through the ranks steadily. Major promotion came within the IJA 7th Division in 1915. August 1930 brought his elevation to major-general. Command of the 5th Infantry Brigade lasted from 1930 until 1934. Lieutenant-general status arrived in August 1934. He led the IJA 4th Division between 1934 and 1937. The Second Sino-Japanese War began while he headed the Imperial Japanese Army Air Service. This tenure spanned from 1937 to 1938. He commanded the IJA 2nd Army stationed in China from 1938 to 1939. Full general rank was awarded in August 1939. He received the Order of the Golden Kite, 1st Class in 1940.

  • A memo discovered by historian Yoshiaki Yoshimi revealed a specific authorization date. Prince Higashikuni ordered poison gas use against Chinese forces on the 16th of August 1938. This decision occurred during his command of the IJA 2nd Army. He returned to Japan in January 1939 after this period. The evidence suggests direct involvement in chemical warfare decisions. His military career continued upward despite these actions. Promotion to full general had already been granted earlier that year. The Order of the Golden Kite recognized his service in 1940. These events remain central to historical analysis of his wartime record. No other source contradicts the existence of this memo or its contents.

  • Outgoing Prime Minister Fumimaro Konoe proposed Prince Higashikuni on the 15th of October 1941. Emperor Shōwa appointed him prime minister on the 17th of August 1945. This appointment replaced navy Admiral Kantarō Suzuki. The mission of the Higashikuni Cabinet focused on two goals. First, ensure orderly cessation of hostilities and demobilization of armed forces. Second, reassure Japanese people that the imperial institution remained secure. Emperor Shōwa chose him following the decision to accept the Potsdam Declaration. Konoe believed only an Imperial Family member could restrain pro-war factions. Generals Hajime Sugiyama, Hideki Tōjō, and Akira Mutō led those factions. Both Chief of Staffs of the Army and Navy supported his selection. The Emperor initially hesitated due to potential blame for war outcomes.

  • Higashikuni died of heart failure in Tokyo on the 20th of January 1990. He was 102 years old at the time of death. He outlived his wife, two sons, siblings, and nephew Emperor Shōwa. At his death, he remained the last surviving full general of the Imperial Japanese Army. From the 14th of May 1988 until his passing, he held the title of world's oldest living former head of government. His tenure remains Japan's shortest-serving prime minister period. He is one of the longest-lived premiers ever recorded. Antoine Pinay, Willem Drees, and Christopher Hornsrud share similar longevity records. He published wartime journals titled Ichi Kozoku no Senso

  • Nikki in 1958. Autobiographical memoirs followed under the name Higashikuni Nikki in 1968. He served as honorary chairman of International Martial Arts Federation starting in 1957.
