Prime Minister from 1916-1918
Tenure as Prime Minster: 721 days.
Born in Yamaguchi (Choshu).

Terauchi was born to a low-ranking samurai family in Yamaguchi (Choshu). As the first inspector general of military education (1898), he worked to systematize military training in the Imperial army. Terauchi served as army minister during the Russo-Japanese War (1904-05) and remained in the post until 1910, when he was appointed the first governor-general of Korea (朝鮮総督), having directed its annexation by Japan. (Treaty of Annexation) His assimilation policies in the following years caused a lot of resistance in Korea, finally leading to a uprising in March 1919.
In 1916 Terauchi was named prime minister with the backing of Yamagata Aritomo, whose faction Terauchi belonged to. Terauchi increasingly became considered the future leader of the Yamagata faction after the dead of Katsura Taro and Kodama Gentaro.
The main foreign policy events of Terauchi's premiership were the so-called Nishihara loans to shore up the government of Duan Qirui (Tuan Ch'i-jui) in China; the Lansing-Ishii Agreement between State Secretary Lansing and Japanese vice foreign minister Ishii Kikujiro, recognizing Japan's special interests in China; and Japanese participation in the Siberian Intervention (シベリア出兵) by Allied forces during World War I. Terauchi was forced to step down with the outbreak of the nationwide rice riots (米騒動) of 1918 that resulted from wartime inflation.
