A former government official of the Ishiba's regime has found himself at the bottom of the proportional representation list. Proportional representation is a pivotal part of Japanese elections and a politician's position can drastically influence their chances of election. The report does not disclose the name of the politician or the specific reason for his low position.

In Japan, the concept of proportional representation holds a significant value in political elections. It provides a fair and equal chance of getting elected to all the politicians irrespective of their political affiliations. However, being ranked low on this list is typically not seen favourably, as it significantly reduces a politician's chances for election.

In the US or the EU, there are different electoral systems. In the US, The Electoral College system is implemented, which is more candidate-based. In the EU, the voting process varies from member state to member state, with some implementing a proportional representation like Japan, and others favoring different systems.
