Nobuhito, Prince Takamatsu

Emperor Taishō's four sons in 1921: Hirohito, Takahito, Nobuhito and Yasuhito

Nobuhito was born at the Aoyama Palace in Tokyo to then-Crown Prince Yoshihito and Crown Princess Sadako. His childhood appellation was Teru-no-miya (Prince Teru). Like his elder brothers, Prince Hirohito and Prince Yasuhito, he attended the boy's elementary and secondary departments of the Peers' School (Gakushuin). When Prince Arisugawa Takehito (1862–1913), the tenth head of the collateral imperial house of Arisugawa-no-miya, died without a male heir, Emperor Taishō placed Prince Nobuhito in the house. The name of the house reverted to the original Takamatsu-no-miya. The new Prince Takamatsu was a fourth cousin, four times removed of Prince Takehito.

Prince Takamatsu attended the Imperial Japanese Naval Academy from 1922 to 1925. He received a commission as an ensign on 1 December 1925 and took up duties aboard the battleship Fusō. He was promoted to sub-lieutenant the following year after completing the course of study at the Torpedo School. The prince studied at the Naval Aviation School at Kasumigaura in 1927 and the Naval Gunnery School at Yokosuka in 1930 - 1931. In 1930, he was promoted to lieutenant and attached to the Imperial Japanese Navy General Staff in Tokyo. He became a squadron commander of cruiser Takao, two years later and subsequently was reassigned to the Fusō. Prince Takamatsu graduated from the Naval Staff College in 1936, after having been promoted to lieutenant commander on 15 November 1935. He was promoted to the rank of commander on 15 November 1940 and finally to captain on 1 November 1942. From 1936 to 1945, he held various staff positions in the Naval General Staff Office in Tokyo.

On 4 February 1930, Prince Takamatsu married Kikuko Tokugawa (26 December 1911 – 18 December 2004), the second daughter of Yoshihisa Tokugawa (peer). The bride was a granddaughter of Yoshinobu Tokugawa, the last Shōgun of the Tokugawa shogunate, and a granddaughter of the late Prince Arisugawa Takehito. Shortly after the wedding, Prince and Princess Takamatsu embarked upon a world tour to Europe and then across the United States so as to strengthen the goodwill and understanding between Japan and those nations. Prince Tokugawa Iesato (also known as Prince Iyesato Tokugawa) was the uncle of Prince and Princess Takamatsu. Prince Tokugawa allied with Prince and Princess Takamatsu on many international goodwill projects.

Prince and Princess Takamatsu had no children.

From the 1930s, Prince Takamatsu expressed grave reservations regarding Japanese aggression in Manchuria and the decision to wage war on the United States.

After the Battle of Saipan in July 1944, Prince Takamatsu joined his mother Empress Teimei, his uncles Prince Higashikuni, Prince Asaka, former prime minister Konoe Fumimaro, and other aristocrats, in seeking the ouster of the prime minister, Tojo Hideki.

After the end of WWII, Prince Takamatsu became the honorary president of various charitable, cultural and athletic organizations including the Japan Fine Arts Society, the Denmark-Japan Society, the France-Japan Society, the Tofu Society for the Welfare of Leprosy Patients, the Sericulture Association, the Japan Basketball Association, and the Saise Welfare Society. He also served as a patron of the Japanese Red Cross Society (present day the Honorary President is Empress Michiko) and was a major contributor of the NBTHK (Nihon Bijutsu Token Hozon Kyokai or Society for the Preservation of the Japanese Sword). He also officiated the Honorary President of the Preparatory Committee for founding International Christian University (ICU) located in Mitaka, Tokyo.

In 1975, the Bungei Shunjū literary magazine published a long interview with Takamatsu in which he told of the warning he made to his brother Hirohito on November 30, 1941, the warning he made to him after Midway and that, before the surrender, he and Prince Konoe had considered asking for the emperor's abdication. The interview implied that the emperor had been a firm supporter of the Greater East Asia War (Japanese name of the Pacific War in those days) while the prince was not.

Prince Takamatsu died of lung cancer on February 3, 1987, at the Japanese Red Cross Medical Center (ja, located in Shibuya, Tokyo). His remains were buried at Toshimagaoka Cemetery located in Bunkyō, Tokyo.

In 1991 the prince's wife Kikuko, Princess Takamatsu and an aide discovered a twenty-volume diary, written in Prince Takamatsu's own hand between 1921 and 1947. Despite opposition from the entrenched bureaucrats of the Imperial Household Agency, she gave the diary to the magazine Chūōkōron, which published excerpts in 1995. The diary in full was published from 1995 to 1997, in eight volumes.

The diary revealed that Prince Takamatsu bitterly opposed the Kwantung Army's incursions in Manchuria in September 1931, the expansion of the July 1937 Marco Polo Bridge Incident into a full-scale war of aggression against China and in November 1941 warned his brother, Hirohito, that the Imperial Japanese Navy could not sustain hostilities for longer than two years against the United States. He urged Emperor Shōwa to seek peace after the Japanese naval defeat at the Battle of Midway in 1942; an intervention which apparently caused a severe rift between the brothers.
