was a Japanese imperial prince and general in the Imperial Japanese Army. He was the 9th head of the line of shinnà Âke cadet branches of the Imperial Family of Japan from 1871.
Prince Arisugawa held several government and military offices during the Meiji era, such as commander of the Imperial Army during the Boshin War and the Satsuma Rebellion, president of the Genrà Âin, Minister of the Left and chief of the army general staff.
Prince Arisugawa Taruhito was born in Kyoto in 1835, as the eldest son of Prince Arisugawa Takahito by Yà «ko (d. 1841), the eldest daughter of Saeki Yà «jà Â. He was adopted by Emperor Ninkà  as a potential heir to the throne, thus making Taruhito the adopted brother of Osahito Shinnà  (the future Emperor Kà Âmei). Arisugawa was a close advisor to both Emperor Kà Âmei and his nephew by adoption, Emperor Meiji.
Prince Arisugawa became engaged to Princess Kazu-no-Miya Chikako, the eighth daughter of Emperor Ninkà Â, on August 8, 1861. However, the engagement was cancelled by the Tokugawa bakufu so that the princess could marry the shà Âgun Tokugawa Iemochi, thus politically sealing the reconciliation between the Shogunate and the Imperial Court.
Arisugawa's first wife Sadako (1850âÂÂ1872) was the eleventh daughter of Tokugawa Nariaki, daimyà  of Mito Domain. His second wife was Tadako (1855âÂÂ1923), daughter of Count Mizoguchi Naohiro, the former daimyà  of Shibata Domain. Neither of these marriages produced any children.
After Emperor Meiji succeeded to the throne in 1867, he appointed Prince Arisugawa Sà Âsai (a position equivalent to chief minister), and placed him in command of the Imperial Army sent to combat the last partisans of the Tokugawa bakufu in the Boshin War of 1868âÂÂ1869. He fought at the Battle of TobaâÂÂFushimi and later travelled up the Tà Âkaidà Â, to accept the surrender of Edo Castle on 3 May 1867, from his former fiancée Princess Kazu. In 1871 he was appointed governor of Fukuoka. Prince Arisugawa later led the Imperial Army against the forces of Saigà  Takamori in the Satsuma Rebellion of 1877. He was given the rank of general in 1878.
From 1876 to 1880 he was the president of the Genrà Âin. From 1880 until the adoption of the Cabinet system in 1885, Arisugawa served as Minister of the Left (左大è£, Sadaijin). In 1882 he travelled to St. Petersburg, Russia, and met with Tsar Alexander III as the official envoy from Emperor Meiji.
From 1889 to 1895 the prince served as chief of staff of the Imperial Japanese Army and a member of the Supreme War Council. In that capacity, he was chief of staff to the Emperor in the Imperial General Headquarters after the outbreak of the First Sino-Japanese War in 1894. In September of that year, he was in charge of establishing the headquarters at Hiroshima Castle.
He contracted typhoid fever (or possibly malaria) and returned to the Arisugawa palace at Maiko near Kobe to recover, but he died there on 15 January 1895. On his death, Emperor Meiji awarded him the first ever Collar of the Supreme Order of the Chrysanthemum. He was accorded a state funeral in Tokyo on 29 January 1895. His half-brother, Prince Arisugawa Takehito, succeeded as the tenth head of the house of Arisugawa-no-miya.
The Arisugawa Memorial Park in Minami-Azabu, Minato, Tokyo occupies the site of the Arisugawa palace and its extensive gardens are open to the public. Although Imperial Prince Taruhito had intended to spend his last days in this palace, he died without ever occupying it. With donations by à Âyama Iwao, Saigà  Tsugumichi and Yamagata Aritomo, a statue of the prince on horseback was made and erected in 1903 by the gate of the Imperial Japanese Army General Staff headquarters; it was moved to this park in 1962.
