Leaders of Japan's ruling Liberal Democratic Party (LDP) are finding it difficult to address the issue of reducing the number of seats in the Lower House during the current parliamentary session. Such an initiative would require close scrutiny and consensus which appears tough to achieve in the congested agenda of the house. The goal to streamline the parliament needs to be balanced against various factions' interests, showing the complexities of democratic decision-making in Japan.

In Japan, reduction of seats in the Lower House is seen as a move towards efficiency and cost-effectiveness in the government, but it incurs resistance as it impacts the power distribution among political factions. Many Japanese citizens are increasingly becoming aware and supportive of political reforms that could lead to more efficient governance.

In the US or EU, the reduction in number of seats in a parliamentary house would also involve careful considerations, extensive debates and consensus building. Redistricting in the U.S., for example, often faces controversies over gerrymandering or preserving balance of representation. In the EU, member countries each have unique methods of seat distribution and adjustment.
