The is a constituency that represents Fukushima Prefecture in the House of Councillors in the Diet of Japan. It currently has two Councillors in the 248-member house.
From the first House of Councillors election in 1947 until the 2010 election, Fukushima elected four Councillors to six-year terms, two each at alternating elections held every three years. In September 2012 Fukushima had 1,627,518 registered voters, the lowest of the 12 prefectures that were represented by 4 Councillors at that time. By comparison, the three most populous districts of Hokkaido, Hyogo at-large district and Fukuoka districts each had more than 4 million voters but were also represented by four Councillors each. To address this malapportionment, a November 2012 amendment to the Public Offices Election Law reduced Fukushima's (and Gifu's) representation to two Councillors. This change began to take effect at the 2013 election, when only one Councillor was elected in Fukushima, and was completed at the 2016 election. The district has 1,607,908 registered voters as of September 2015.
The Councillors currently representing Fukushima are:
