Item Overview
Political party requirements: (1) 5 or more Diet members, or (2) 1 or more Diet member plus 2% or more of the votes cast in the most recent lower house or upper house regular election.
Calculation framework of the amount The total amount of 31.53 billion yen (in 2025) is divided proportionally by "50% for the number of councilors" + "50% for the number of votes".
Percentage of number of councilors (50%) 1 out of 713 seats = approx. 22 million yen/year
Vote share (50%) If just above the 2% line, the weighted after-weighted share will be around 0.4-0.6% → approx. 50-70 million yen/year
Approximate annual total: 70-90 million yen
Six-year total (upper house term): 400-500 million yen or less (variable if the number of votes received increases or decreases due to lower house elections along the way)
TABLE:Actual examples show the range of "1 seat + 2-3% of the vote".
Fiscal year Political parties Seats per seat per year
2022 参政党（初選選） 1 77 million yen 77 million yen
2025 Conservative Party of Japan 3 172 million yen 57 million yen

Political party subsidies in 25 years, LDP ¥13.63 billion, 9 parties total ¥31.53 billion：Asahi Shimbun
It is a type of participatory budgeting in that the citizens vote to decide how much of the budget to distribute to which teams.
The hurdles are high where political parties are formed.
The more easily they are made, the closer we are to participatory budgeting.
