Ozawa's insistence on a more assertive role for Japan in international affairs caused friction with members of the Japan Socialist Party in the coalition. Eventually, the Socialists left to form a coalition with the LDP, leaving Tsutomu Hata in charge of a minority government that fell in June 1994. Many, including Hata, blamed Ozawa for the loss. Ozawa himself began to move into the public eye, especially with the arrival of the New Frontier Party. Former Prime Minister Toshiki Kaifu had founded the New Frontier Party in 1994. After joining the coalition, it became a catch-all party for the merger of several smaller parties.
