The Japan Masses Party (Japanese: 日本大衆党, Nihon Taishūtō) was a proletarian political party in Japan.
History
The Japan Masses Party was established in December 1928 by a merger of the Japan Labour-Farmer Party (which had won one seat in the 1928 elections), the Japan Farmers Party, the Proletarian Masses Party and four other working-class parties. With both parties from the right and left having joined the new party, tensions soon arose, resulting in the expulsion of several MPs in May 1929.
With a campaign based on tenancy and unemployment issues, the party nominated 23 candidates in the February 1930 elections, winning two seats. In June 1930 it merged with the National Conference for a United Proletarian Party and the National People's Party to form the National Masses Party.
