2025 Tokyo prefectural election

Background

Movements by political party 2021–2025

Liberal Democratic Party and Komeito

• In the previous 2021 election, LDP became the largest party in the Metropolitan Assembly. Nevertheless, doubts have been cast on the funding parties held following the 2024 general election in which some of the lawmakers failed to declare part of its income. An investigation found that the total amount of money not accounted for in the party's Income Declaration over the past five years was 30 million yen. After this information was disclosed, the LDP group in the assembly decided to dissolve its political organisation, excepting the assembly group.
• The Tokyo branch of Komeito decided not to refer any LDP candidates in the assembly, regardless of whether or not undeclared income existed, after learning about the issues surrounding the LDP funding parties.

• Tomin First, for which Governor Yuriko Koike serves as senior advisor, lost its position as the main party in the assembly to the LDP. Regarding this election, it has collaborated with the DPFP since November 2024 in areas such as district redistribution of power.

Opposition Parties

• The branches of the JCP and CDP at the Tokyo Assembly re-edited their collaboration for the 2024 gubernatorial election, in which both parties backed Renho as their candidate. They also declared their plans to collaborate in one to three districts. The aim is to prevent the ruling parties from achieving a majority in the assembly.
• The JCP announced its aim to secure their current 19 seats in the assembly and increase them.

• On 15 January, Shinji Ishimaru, who came second in the 2024 gubernatorial election, announced the foundation of a new party called The Path to Rebirth, for which he is fielding candidates in every electoral district.
