Junya Ogawa, a centrist and former Secretary General of the Constitutional Democratic Party, has likely won his eighth term in Kagawa District 1. His political visibility increased after the success of the documentary 'Why Can't You Become the Prime Minister?' released in 2020. However, this election was closely contested against a former member of the ruling Liberal Democratic Party, contrasting with Ogawa's previous win where he had a margin of over 30,000 votes.

In the current election, Ogawa campaigned on a centrist platform, which subsequently put him in a tight race with the incumbent from the Liberal Democratic Party. This shift in his candidacy from a more left-leaning to a centrist approach reflects the broader political dynamics in Japan, where centrist candidates may increasingly appeal to a changing electorate.

The Kagawa District 1 race symbolizes the ongoing challenges faced by the Constitutional Democratic Party as they seek to maintain their relevance against the dominant Liberal Democratic Party, particularly in light of shifting voter preferences. Ogawa's victory will likely have implications for the party's strategies in upcoming elections and its leadership roles, especially in light of potential upcoming changes in the political landscape.
