Kishi was born Nobusuke Sat in Tabuse, Yamaguchi Prefecture, but left his family at a young age to move in with the more affluent Kishi family, adopting their family name. His biological younger brother, Eisaku Sat, would also go on to become a prime minister. He is also the grandfather of the current prime minister of Japan Shinz Abe. Kishi attended Tokyo Imperial University (now the University of Tokyo) and entered the Ministry of Commerce and Industry in 1920. As a young man, Kishi was a follower of the Japanese fascist Ikki Kita whose writings called for a sort of monarchical socialism for Japan., A general election took place in Japan on October 20 , 1996 . 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.
