was a member of the Japanese imperial family and general of the army who served as prime minister of Japan from 17 August 1945 until his resignation two months later on 9 October. He is the only member of the Japanese imperial family to head a cabinet, and Japan's shortest-serving prime minister, serving for only 54 days.
Born in Kyoto, Prince Higashikuni was a son of Prince Kuni Asahiko and married Toshiko, Princess Yasu, a daughter of Emperor Meiji, thus making him an uncle-in-law of Emperor Hirohito. He graduated from the Army Academy and War College, and studied military tactics in France from 1920 to 1926. Upon his return to Japan, he was promoted to general in 1930 and held several military posts, including as commander of the General Defense Command from 1941 to 1944.
Prince Higashikuni's appointment as prime minister following the war reflected a hope that his prestige as an imperial prince would help to unite the defeated country. He presided over the signing of the surrender on 2 September 1945 and the disbandment of the armed forces before resigning in opposition to an order by the Allied occupation authorities to abolish the Peace Preservation Law. He became a commoner after the abolition of the princely houses in 1947, and later formed a Buddhist sect. He is the longest-lived of Japan's premiers, dying in 1990 at the age of 102.
Prince Naruhiko was born on 3 December 1887 in Kyoto, the ninth son of Prince Kuni Asahiko (Kuni no miya Asahiko Shinnà Â) and the court lady Terao Utako. His father, Prince Asahiko, was a son of Prince Fushimi Kuniie (Fushimi no miya Kuniie Shinnà Â), the twentieth head of the Fushimi-no-miya, the oldest of the sesshu shinnà Âke or cadet branches of the imperial dynasty from whom an emperor might be chosen in default of a direct heir. Prince Naruhiko was a half-brother of Prince Kuni Kuniyoshi, the father of the future Empress Kà Âjun, the wife of Emperor Shà Âwa. His other half-brothers, Prince Asaka Yasuhiko, Prince Nashimoto Morimasa, and Prince Kaya Kuninori, all formed new branches of the imperial family (à Âke) during the Meiji period.
Emperor Meiji granted Prince Naruhiko the title Higashikuni-no-miya and permission to start a new branch of the imperial family on 3 November 1906. Prince Naruhiko married the ninth daughter of Emperor Meiji, Toshiko, Princess Yasu (11 May 1896 â 5 March 1978), on 18 May 1915. The couple had four sons.
Prince Higashikuni Naruhiko was a career officer in the Imperial Japanese Army. In 1908, he graduated from the Imperial Japanese Army Academy as a second lieutenant, was promoted to lieutenant in 1910 and to captain in 1913. In 1914, he graduated from the Army War College. He was commissioned a captain in the 29th Infantry Brigade and promoted to major in the IJA 7th Division in 1915.
Prince Higashikuni then studied military tactics at the ÃÂcole Spéciale Militaire de Saint-Cyr and ÃÂcole Polytechnique in Paris France, from 1920 to 1926, during which time he was promoted to lieutenant-colonel in 1920 and to colonel in 1926. Always somewhat of a rebel, Prince Higashikuni's behavior in Paris scandalized the Imperial Court. He had a French mistress, and enjoyed fast cars and high living. He left his wife and children in Japan, and the death of his second son did not prompt his return. In 1926, the Imperial Household Ministry dispatched a chamberlain to Paris to collect him.
Upon his return to Japan, he was assigned to the Imperial Japanese Army General Staff Headquarters. Promoted to major-general in August 1930 and appointed commander of the 5th Infantry Brigade (1930âÂÂ1934), he was promoted to lieutenant-general in August 1934 and given command of the IJA 4th Division (1934âÂÂ1937). After the start of the Second Sino-Japanese War, he headed the Imperial Japanese Army Air Service (1937âÂÂ1938), and the IJA 2nd Army stationed in China from 1938âÂÂ1939. He was promoted to general in August 1939. According to a memo discovered by historian Yoshiaki Yoshimi, Prince Higashikuni authorized the use of poison gas against the Chinese on 16 August 1938. Prince Higashikuni returned to Japan in January 1939. Promoted to full general, the prince was awarded the Order of the Golden Kite, 1st Class in 1940.
Before Japan entered the Second World War, on 15 October 1941, outgoing Prime Minister Fumimaro Konoe proposed Prince Higashikuni to Emperor Shà Âwa as his successor for prime minister. Konoe believed that only a member of the Imperial Family with a distinguished military background could restrain the pro-war faction led by Generals Hajime Sugiyama, Hideki Tà Âjà Â, and Akira Mutà Â. Prince Higashikuni was also the choice of both Chief of Staffs of the Army and the Navy.
However, both Emperor Shà Âwa and the Lord Privy Seal, Kido Kà Âichi, believed that it would be inappropriate for a member of the Imperial Family to serve in that position, as he could be blamed for anything which went wrong in the war. Thus, two days later, the Emperor chose army minister General Hideki Tà Âjà  as prime minister. In 1946, he explained this decision: "I actually thought Prince Higashikuni suitable as Chief of Staff of the Army; but I think the appointment of a member of the Imperial house to a political office must be considered very carefully. Above all, in time of peace this is fine, but when there is a fear that there may even be a war, then more importantly, considering the welfare of the imperial house, I wonder about the wisdom of a member of the Imperial family serving [as prime minister]."
Six weeks later, Japan attacked Pearl Harbor. Prince Higashikuni served as commander of the General Defense Command from 1941 to 1944.
Prince Higashikuni remained steadfast in his opposition to the war with the Allied powers, and was part of the conspiracy (with Prince Yasuhiko Asaka, Prince Nobuhito Takamatsu, and former prime minister Konoe) which finally ousted Tà Âjà  in July 1944 following the fall of Saipan to American forces. The American researchers with SCAP also found out that he had planned towards the end of the war to depose Emperor Shà Âwa, placing the Crown Prince Akihito on the throne instead, governing the country with himself as regent.
After the course of the war turned against Japan, and the decision was made to accept the Potsdam Declaration, the Emperor Shà Âwa appointed Prince Higashikuni to be prime minister on 17 August 1945, replacing navy Admiral Kantarà  Suzuki. The mission of the Higashikuni Cabinet was twofold: first, to ensure the orderly cessation of hostilities and demobilization of the Japanese armed forces; and second, to reassure the Japanese people that the imperial institution remained secure. Prince Higashikuni resigned in October over a dispute with the Allied occupation forces over the repeal of the 1925 Peace Preservation Law. This law was largely intended to prevent the spread of Communism to Japan.
On 27 February 1946, Prince Higashikuni gave an interview to the Yomiuri-Hà Âchi newspaper in which he claimed that many members of the imperial family had approved Emperor Shà Âwa's abdication, with Nobuhito, Prince Takamatsu serving as regent until Crown Prince Akihito came of age. In the government, only Prime Minister Kijà «rà  Shidehara and the Imperial Household Minister Yoshitami Matsudaira opposed this. On 4 March 1946, Higashikuni gave a similar interview to the Associated Press (reported in The New York Times) indicating that he had proposed to the Emperor possible dates for abdication.
In 1946, Prince Higashikuni asked the emperor for permission to renounce his membership in the Imperial Family and become a commoner. The emperor denied the request. However, along with other members of the Imperial branch families (shinnà Âke and à Âke), Prince Higashikuni lost his title and most of his wealth as a result of the American occupation's abolition of the princely houses on 17 October 1947.
As a private citizen, Higashikuni operated several unsuccessful retail enterprises (including a provisions store, second-hand goods store, and dressmaker's shop). He even created his own new Zen Buddhism-based religious sect, the Higashikuni-kyo, which was subsequently banned by the American occupation authorities.
The former prince became the honorary chairman of the International Martial Arts Federation (IMAF) in 1957, and honorary president of several other organizations.
In 1958, Higashikuni published his wartime journals under the title, Ichi Kozoku no Senso Nikki (or The War Diary of a Member of the Imperial Family). He published his autobiographical memoirs, Higashikuni Nikki, in 1968.
Higashikuni died of heart failure in Tokyo on 20 January 1990 at the age of , having outlived his wife, two of his sons, his siblings, and his nephew, Emperor Shà Âwa. Higashikuni is today mainly remembered as the first postwar prime minister of Japan. He is the shortest-serving prime minister, resigning after eight weeks (54 days) and one of the longest-lived prime ministers of all time, along with Antoine Pinay, Willem Drees and Christopher Hornsrud. At his death, he was the last surviving full general of the Imperial Japanese Army. From 14 May 1988, when former Prime Minister of the Netherlands Willem Drees died, until his own death, Higashikuni was the world's oldest living former head of government.
