新党さきがけ
The JSP then formed a grand coalition ("dai-renritsu") government with the LDP and the New Party Sakigake under JSP Prime Minister Tomiichi Murayama, who was leader of the party from 1993 to 1996. Most of the other parties from the anti-LDP coalition, now forced back into opposition, united to form the New Frontier Party (NFP), which overtook the JSP as second largest political party in Japan. The JSP suffered a defeat in the 1995 Japanese House of Councillors election.
