Background

[edit]

In 2019 election, Kiyoshi Adachi, a independent recommended by four opposition parties, including the Former CDP, defeated Yōsuke Isozaki, a current member of the House of Councillors belonging to the Liberal Democratic Party, and was elected for the first time in Ōita at-large district.[1] Meanwhile, in the 2022 election, Shinya Adachi, a member of the opposition Democratic Party For the People and a current member of the Oita at-large district, lost to the ruling LDP candidate because of the division of the opposition camp.[2]

Adachi announced his candidacy for Ōita Prefecture gubernatorial election and resigned as a member of the House of Councillors on March 10, 2023.[3] With Adachi's resignation, by-elections will be held on April 28, 2023, under the Election Law.

The LDP has nominated Aki Shirasaka, the owner of Inaba, a club in Ginza, as its candidate.[4] On the other hand, main opposition party, the CDP, nominated Tadatomo Yoshida, a former leader of the Social Democratic Party who left the SDP and joined the CDP in 2020, as a candidate.[5]

After the assassination of Shuzo Abe, the LDP's collusion with the Unification Church was discovered, and the match drew national attention as it was a one-on-one battle between the ruling and opposition parties amid falling approval ratings of the Kishida administration.[6][7][8]
