The conclusive victory of the Liberal Democratic Party (LDP) in Japan has sparked off discussions on election system reform. Riding on a wave of popularity, the LDP now holds a solid supermajority. This power shift is prompting rigorous debates on potential changes to the election process aimed at promoting more fair and balanced representation. Details around when and what specific changes are yet to be determined.

In Japan, political stability is highly valued, and the recent LDP victory is seen as a sign of this stability. However, it also brings potential changes to the foreground. Japan has a parliamentary system where the party with the majority forms the government. Although the LDP's control is secure, there is public sentiment pushing for more representation from other parties. Hence, election reform is a topic of high interest.

In the US, the two-party system is the norm, unlike Japan’s multi-party system. Changing election systems is a contentious issue in both countries, with each harboring factions advocating for reforms and against them. The EU, with its diverse member states, showcases a variety of election systems, many of which are proportional representing multiple parties, much like Japan.
