日本众议院改选，高市早苗作“独狼”式豪赌

Group 1 - The Japanese Prime Minister, Sanna Takashi, submitted a resolution to dissolve the House of Representatives on the first day of the 2026 regular session, marking the first time in 60 years that the House was dissolved immediately after the session began [1] - Takashi has been active since taking office, pushing through an 18 trillion yen supplementary budget and facilitating a 550 billion USD investment from the U.S., resulting in a rare increase in her approval ratings, exceeding 70% overall and over 80% among younger demographics [1] - The dissolution aims to capitalize on her high approval ratings and force a re-election, similar to former Prime Minister Junichiro Koizumi's strategy 20 years ago, which significantly increased the ruling party's seats [1][2] Group 2 - The last election saw the ruling coalition fail to secure a majority, but a successful re-election could allow Takashi to gain control over legislative decisions, solidify her political base, and enhance her standing within the Liberal Democratic Party (LDP) [2] - Takashi's decision to dissolve the House was made without consulting key party figures, indicating a lack of internal support and complicating her position amid ongoing political scandals [2] - The establishment of the "Center Reform Coalition" by the largest opposition party, the Constitutional Democratic Party, in collaboration with the Komeito Party, aims to consolidate middle-ground voters and challenge the ruling party [3]
