sōsai

The Japanese word Sosai (Japanese:総裁, "Sōsai") means roughly "president" or "director-general". It is used in several ways:

==Political== Sosai, or president of the government, was only once the title of the imperial prime minister: from 1 January 1868 (before there was no cabinet, only chief advisers: Kampaku to the nominally reigning emperor and both Rōjū and Tairō to the de facto ruling shōgun) until 11 June 1868: Prince Arisugawa Taruhito (1835–1895); next the prime ministerial office is styled U Daijin "Ministers to the Right", in 1871 shortened to Daijin. Sosai also was the title of Tokugawa Admiral Takeaki Enomoto (1836–1908), the elected president (27 January 1869 – 27 June 1869) of the short-lived rebellious Ezo Republic on the present Hokkaidō Island, vanquished by Imperial troops. Sosai, or President of Liberal Democratic Party, is the office of the head of the LDP.
