Tetsuzo Fuwa (不破 哲三, Fuwa Tetsuzō, born 26 January 1930) is the pen name of Kenjiro Ueda (上田 建二郎, Ueda Kenjirō),[1] a member[2] and the former chairman of the Japanese Communist Party.

[1] In around 1972, Fuwa, replacing certain senior party members, was placed in higher positions within the JCP as part of the JCP's attempts at changing its image and courting younger voters, with the Asahi Shimbun commenting on Fuwa's "eloquency, gentle manner and good looks" in connection to the JCP's electoral strategy.

Fuwa was one of the figures in the party who were instrumental in the movement to change the JCP's general image from that of a violent revolutionary group to a reformist and democratic one.

[5] Fuwa was eventually selected to be the chairman of the JCP from 1982 to 1987; he held the position again from 1989 to 2000.

[6] He stepped down as a member of the party's executive committee as a result of the resignation of his successor as chairman, Kazuo Shii, in 2024.
