国际观察｜26年政治联盟破裂 日本进入“多党化时代”？

Core Viewpoint - The Komeito party's decision to exit the ruling coalition with the Liberal Democratic Party (LDP) marks the end of a 26-year alliance, potentially leading Japan into a "multi-party era" due to ideological differences and electoral challenges [1][10]. Group 1: Reasons for the Split - The Komeito party's call for stricter regulations on political donations from businesses and organizations was not satisfactorily addressed by the LDP, prompting the split [2][4]. - The appointment of controversial figures within the LDP, such as former Prime Minister Taro Aso and Koichi Hagiuda, has contributed to Komeito's dissatisfaction and loss of trust [4][5]. - Fundamental ideological differences exist between the conservative LDP and the liberal Komeito, particularly regarding constitutional amendments and nationalistic sentiments [4][10]. Group 2: Political Implications - The upcoming prime ministerial election in the Diet is critical, as Komeito's withdrawal means the LDP can no longer rely solely on the Democratic Party for support to secure a majority [6][7]. - The potential for increased political maneuvering among opposition parties, particularly the Constitutional Democratic Party and the Democratic Party for the People, could reshape the political landscape [9][10]. - Analysts suggest that Japan may be entering a phase of political fragmentation, similar to the 1990s, where no single party can dominate, leading to instability and challenges in governance [10][12].
