Katsura Tarō, Japanese general and politician, 6th Prime Minister of Japan (b. 1848)

Prince Katsura Tarō (桂 太郎, 4 January 1848 – 10 October 1913) was a Japanese politician and general of the Imperial Japanese Army who served as the Prime Minister of Japan from 1901 to 1906, from 1908 to 1911, and from 1912 to 1913.

Katsura was a distinguished general of the First Sino-Japanese War and a genrō of the Meiji government who served as Governor-General of Taiwan and Minister of War. Katsura was appointed Prime Minister in 1901 as a military candidate and positioned himself as a conservative outside party politics. Katsura's first and second premierships oversaw several major events in modern Japanese history, including the Russo-Japanese War and the annexation of Korea. Katsura's third premiership triggered the Taisho Political Crisis, and he resigned three months later after a vote of no confidence.

Katsura is the second-longest serving Prime Minister of Japan, after Shinzō Abe, and served for 2883 days over his three terms from 1901 to 1913.
