The district was created in the 1994 electoral reform from parts of the previous 1st district where six representatives had been elected by single-non-transferable vote. Representatives from the old 1st district included Kingo Machimura and his son Nobutaka Machimura.
Nobutaka Machimura (LDP, Machimura faction) safely won the new 5th district in the 1996 election and defended it against Democratic challenger Chiyomi Kobayashi in subsequent elections. However, the Democratic Party won the general election of 2009 handily, and Kobayashi defeated Machimura by 30,000 votes. In response to a political funds scandal, she resigned in June 2010. Machimura resigned from his seat in the Hokkaidō proportional block to run in the resulting by-election in October 2010 and defeated former construction ministry bureaucrat Shigeyuki Nakamae by a clear margin to regain his district seat.The Japan Times, Oct. 25, 2010: LDP vet clinches Hokkaido by-election
In the 24 April 2016 by-election, Machimura's son-in-law, Liberal Democrat Yoshiaki Wada (Kōmeitō, Kokoro, Daichi) defeated united opposition independent Maki Ikeda (DP, JCP, SDP, PLP).NHK News, 25 April 2016: 衆院補選 北海道5区は自民 和田義明氏が当選 Hokkaidō Shimbun, 24 April 2016: 北海道5区補選、自民新人の和田氏勝利 池田氏、猛追及ばず Wada held the seat until he lost to Ikeda in the 2024 election. Wada was accused of receiving 'dark money' in the 2023–2024 Japanese slush fund scandal. Subsequently, the LDP did not allow Wada to run in the Hokkaidō PR block and he lost his seat in the Diet.
