2021 Japanese general election in Shikoku

The 2021 Japanese general election in Shikoku were held on October 31, 2021, to elect the 17 representatives, one from each of 11 Electoral districts and 6 proportional seats.

Tokushima 1st district
Masazumi Gotoda, an incumbent member of the Liberal Democratic Party, was at odds with Tokushima Governor Kamon Iizumi and members of the LDP's Tokushima Prefectural Assembly. The Tokushima prefectural branch of the Liberal Democratic Party asked the LDP headquarters not to nominate Goto-ta as a candidate, but the headquarters nominated him as a candidate. But because of the split, Gotoda lost his seat to Hirobumi Niki, an independent opposition party, after failing to receive no support from the Tokushima prefectural branch. Later, Goto won a proportional representation seat and maintained his seat in the House of Representatives, but resigned to run for governor of Tokushima Prefecture in January 2023.

In April 2023, Gotoda was elected governor of Tokushima Prefecture for the first time, defeating incumbent Kamon Iizumi and Tōru Miki, who is former LDP member of the House of Councillors. About six months later, Niki, who ran as an independent opposition party, joined the LDP and LDP eventually regained the seat in this constituency.
