Incumbent Prime Minister Ryutaro Hashimoto of the coalition of the Liberal Democratic Party , New Party Sakigake and the Social Democratic Party won the election . This is the first election under new elections rules established in 1993 with single non-transferable vote , single - member districts , and some seats being distributed according to proportional representation . Before this election , each district was represented by multiple members , sometimes from the same party , causing intra-party competition . Under the new rules , each district has only one representative now representing a wide range of interests for his or her district . A separate party - list was introduced for voters to choose their favored party ( in addition to votes for individual candidates ) as a way to more accurately approximate the seats in the House of Representatives of Japan to the actual party votes in an effort to achieve more proportional representation . With only a single member in each district , this change allows for more district - wide benefits . This is opposed to the old multi-member districts where each representative appeals to either policy or geographic - based benefits to narrow interests in their constituencies , who in turn help their member 's campaign in their reelection efforts . - Early political life. Hashimoto was born on 29 July 1937, in Sja in Okayama Prefecture. His father, Rygo Hashimoto, was a cabinet minister under Prime Minister Nobusuke Kishi. Following his father's lead, Ryutaro received his degree in political science from Keio University in 1960, and was elected to the House of Representatives of Japan in 1963.
