The Essay is focused on the new election system of Japanese House of Representatives' to find out the roles of election system in Japan democratic Progress. To perfect the electoral system, Japan had mended its election system of the House of Representatives 14 times since 1889 till 1994. In 1993, some political issues, included the reform of election system, eventually led Prime Minister Miyazawa Kiichi to resign and ended the Liberal Democratic Party' 38-year-old reign, as well as the so-call"55 system（the party system of 1955）".During the past century, Japan has tried small, medium and large sized district systems, currently "First past the post with Proportional Representation System", to constitute a fair and better system which is expected to improve Japan's political environments and make voters trust the politics.

中文摘要本论文系以日本众议院新选举制度为研究之核心，探讨日本在其民主化过程中，选举制度所扮演之角色，日本为让选举制度更臻完善，自一八八九年起至一九九四年止，共计针对其众议院选举制度进行了十四次之修改，甚至於一九九三年，因选举制度等政治议题之改革，导致自由民主党之宫泽喜一内阁下台，结束该党长达三十八年之长期执政，日本政治上所谓「五五体制」亦至此宣告结束，过去百余年来日本先后实施过小选举区制、中选举区制、大选举区制及目前实施之小选举区比例代表并立制，其主要目的系为建构一套更公正、公平、优质之选举制度，让其政治更清明，让选民对政治更有信心。
