The Japan Liberal Party (日本自由党, Nihon Jiyūtō) was a political party in Japan.
The Japan Liberal Party was founded on November 9, 1945, mainly by former members of Seiyukai Party, with Ichirō Hatoyama being its first leader.
From 1946-1954 the next party leader Shigeru Yoshida served as Prime Minister.
In 1948 the Japan Liberal Party merged with Kijūrō Shidehara's Dōshi Club (民主クラブ), and a faction of the Democratic Party led by Saitō Takao, to form the Democratic Liberal Party (民主自由党, Minshu Jiyūtō).
