Niigata at-large district
The Niigata at-large district (Japanese: 新潟県選挙区, Hepburn: Niigata-ken senkyoku) is a constituency that represents Niigata Prefecture in the House of Councillors in the Diet of Japan. Since July 2019, it has two Councillors in the 242-member house, a decrease from its previous contingent of 3.
Outline
The constituency represents the entire population of Niigata Prefecture and has 1,925,565 registered voters as of September 2015.[1] Since the first House of Councillors election in 1947 Niigata has elected four Councillors to six-year terms, two at alternating elections held every three years. The district's number of voters is the third-lowest of the 10 prefectures that are represented by four Councillors; by comparison, the Hokkaido, Hyogo at-large district and Fukuoka districts each have more than 4 million voters but are represented by the same number of Councillors as Niigata.[1] To address this malapportionment in representation, a 2015 revision of the Public Officers Election Law decrease the representation of Niigata, Miyagi and Nagano districts to two Councillors while increasing Hyogo, Hokkaido and Fukuoka districts to six Councillors.[2] This change took effect at the 2016 election, after which time, Niigata will elect only one Councillor during every election.
The Councillors currently representing Niigata are:
- Kazhiro Kobayashi (LDP, first term; term ends in 2028)[3]
- Sakura Uchikoshi (CDP, first term; term ends in 2025)[4]
