Aichi at-large district

The Aichi at-large district is a constituency of the House of Councillors in the Diet of Japan that represents Aichi Prefecture. From 1947 until 2013 it has elected six Councillors, three every three years by single non-transferable vote (SNTV) for six-year terms. A 2015 revision of the Public Officers Election Law increased the district's representation to eight Councillors;^[1] the change began to take effect at the 2016 election, at which four Councillors were elected.

The Councillors currently representing Aichi are:

• Masahito Fujikawa (Liberal Democratic Party (LDP); term ends in 2022)
• Takae Ito (Democratic Party (DP); term ends in 2022)
• Kōhei Ōtsuka (DP; term ends in 2019)
• Yoshitaka Saitō (DP; term ends in 2022)
• Yasuyuki Sakai (LDP; term ends in 2019)
• Ryuji Satomi (Komeito; term ends in 2022)
• Michiyo Yakushiji (elected as a Your Party candidate, independent since the party's 2014 dissolution; term ends in 2019)
