National Party (Japan)

The party was established in July 1946 as the Shinseikai (New Politics Society) by a merger of the Shinkō Club, some independent MPs and some MPs from the Preparatory Committee for the Japan Democratic Party,^[2] which was subsequently dissolved.^[3] It initially had 40 MPs, two of whom were amongst the eight MPs who voted against the new post-war constitution. Talks were held with the Cooperative Democratic Party about a merger in August 1946, and after they fell through, the party was renamed the National Party.^[2]

By September 1946 the party had been reduced to 33 MPs.^[1] In March 1947 another attempt was made to merge with the Cooperative Democratic Party, which this time was successful, resulting in the creation of the National Cooperative Party.
