In 1996 the seat was won by Democratic Party of Japan member Tadamasa Kodaira, who had been one of the representatives of the former 4th district since 1990. Kodaira retained the seat at the following four elections, until his loss to Komeito candidate Hisashi Inatsu at the 2012 general election. Inatsu retained the seat in subsequent elections until 2024.
