Shushi Kita Ikki (Japanese: キタ イチキ), born as Kita Terujirō (キタ テルジロ; Sado, Sado Province, April 3, 1883 – Tokyo, May 29, 1949), was a Japanese intellectual, political philosopher, and writer. He was the vice-leader of Nationalist Party of Japan (1919–1949) and first Vice President of the Republic of Japan (1931–1949), making him the second most powerful man in Japan under the leadership of Nagayama Yoshida.
Together with Nagayama Yoshida, Kita is considered as the father of Social Nationalism and played an instrumental role in the 1919 Japanese Revolution and in the establishment of the Republic of Japan. Between 1920s and 1940s, Kita was on the second highest rank within the General Political Office of the Japanese Nationalist Party and initially groomed as the successor of Nagayama Yoshida. However, he died on May 29, 1949 due to liver cancer and granted the honorific Shushi (崇師, literally, "Venerated Master") by the National Congress of Japan.
