## History

Before 1996, the amendment of Public Offices Election Act that introduced FPTP “small” voting system, this area had been part of former Niigata 1st district where three representatives had been elected by single non-transferable vote. The two candidates contesting the former 1st district, Rokuzaemon Yoshida (LDP) and Nobuyuki Sekiyama (DPJ), had continued to run until 2000.
In the 2003 general election, the Democratic Party of Japan fielded Chinami Nishimura, former Member of Niigata Prefecture Assembly, who defeated Yoshida in the 2003, 2005 and 2009 elections. In 2012, when the Democratic Party lost the reins of government, Tooru Ishizaki, a new LDP candidate, defeated Nishimura. In 2014, Nishimura was defeated again, but elected through the proportional representation block.
In the 2017 general election, Nishimura joined the Constitutional Democratic Party, and defeated Ishizaki. Ishizaki was elected through the proportional representation block. In 2020, after Ishizaki was indicted for verbally and physically assaulting his secretary, he left the LDP and ran as a Nippon Ishin no Kai candidate in the 2021 elections.
