Ishimaru's recently formed political party is facing a setback as multiple candidates for the upcoming Tokyo's Metropolitan Assembly elections have announced their departures. The party, renowned for its progressive stances, is now thrust into unexpected turmoil as it loses its most prominent players ahead of a crucial political event. The reasons behind the sudden defections remain unclear, signaling a possibly turbulent period in Tokyo's political landscape.

Political defections are often seen as a significant event in Japanese politics, stirring up public interest and debate. This is especially true when they occur before the Metropolitan Assembly elections, which are regarded as important indicators of public opinion toward national politics. In Japan's consensus-oriented society, such a wave of defections could potentially damage the party’s image, forcing it to reassess its strategies.

In the US or the EU, similar issues also generate significant interest. Political defections indicate disagreement within the party, reflecting on the party's leadership and its ability to garner support for its policies. It could affect a party’s prospects in upcoming elections and might trigger internal reforms or realignment of party stances.
