Debates flare up among Japanese centrist parties over the preferential treatment given to Komeito Party under the proportional representation system. Critics argue that this favours one party unduly, skewing the political playing field. The friction underscores a wider conflict over electoral reform within Japan's political corridors, posing potential obstacles to consensus in the run-up to the next election.

The issue of proportional representation is hotly debated in Japan, with various parties advocating for different systems that would best represent their interests. The Komeito Party, being a part of the ruling coalition, receives favourable treatment which has been a source of contention among centrists. This taps into broader conversations about democratic representation, electoral fairness, and party politics in the country.

Unfair representation and gerrymandering are contentious issues in the U.S. and the EU as well. Debates are ongoing on how to ensure fair representation of the electorate. However, unlike Japan, the discussions in the U.S. and EU often revolve around geographical boundaries (redistricting) rather than preferential treatment of a certain party.
