The Democratic Party of Japan (民主党, Minshutō) was a centrist[1][2][3] political party in Japan, and one of the forerunners to the Democratic Party of Japan formed in 1998.

Its two leading members, Yukio Hatoyama and Naoto Kan, subsequently and sequentially became Prime Ministers at the end of the first decade of the 21st century.

The party was founded on 29 September 1996 by sitting members of the Diet,[4] and was composed mostly of former Sakigake and Japan Socialist Party politicians who did not support an alliance with the ruling Liberal Democratic Party.
