Kiuchi Jushiro (?? ???, 26 January 1866 – 9 January 1925) was a Japanese politician.
He was educated at Chiba Middle School and Chiba First High School, and later graduated from Imperial Tokyo University's Department of Political Science.
In 1906, while serving as a Japanese representative in Korea, Kiuchi made a bet with Durham Stevens, an American advisor to the Korean government, about the length of time before Japan would annex Korea.
Kiuchi expected it would only take three years; Stevens' guess of five years would prove to be more nearly correct, as the Japan–Korea Annexation Treaty was signed in mid-1910.
In January 1909, Kiuchi was one of a number of politicians who brought pressure to bear against Ito Hirobumi and his allegedly soft policies towards Korea, urging that Japan should exercise direct rule there; it was suggested that Kiuchi took this position due to his dissatisfaction with being shifted from Vice-Minister of Home Affairs to Vice-Minister of Agriculture.
He later served as a member of the House of Peers and then from 1916–1918 as governor of Kyoto Prefecture.Kiuchi's former residence, located in Ichikawa, Chiba, was maintained as a historical building and tourist attraction for some years, but was being considered for dismantling as of 2001.
