On the 8th, a group of lawyers filed a nationwide lawsuit seeking to invalidate the House of Representatives election, claiming that the disparity in the value of one vote, which was as large as 2.1 times, violated the Constitution.

In this House of Representatives election, there was a 2.1-fold difference in the value of one vote between Tottori 1st District, which had the fewest number of voters, and Hokkaido 3rd District, which had the most.

On the 9th, a group of lawyers filed lawsuits in 14 high courts and their branches across the country, seeking to invalidate the elections in all single-seat constituencies, claiming that they "violate the equality of voting value and are unconstitutional."

In the last House of Representatives election in 2024, the "Adams Method," a method of allocating seats that is more proportional to population, was applied for the first time, and changes were made to the electoral districts, such as "adding 10 and subtracting 10" single-seat districts, resulting in a maximum disparity in the value of one vote of 2.06 times.

The Supreme Court ruled last year that this was not unconstitutional.

At a press conference, Hidetoshi Masunaga, a lawyer for the group that filed the lawsuit, said, "Unlike the United States and France, Japanese elections are unique in that there is a one-vote disparity and they are not proportional to the population. They should be brought into line with international standards."

Another group of lawyers also filed suit

Also on the 9th, another group of lawyers filed lawsuits in the Tokyo and Hiroshima High Courts seeking to invalidate the election.

Attorney Michihiko Misao held a press conference in Tokyo and said, "In order for the majority vote in the Diet to properly reflect the will of the people, each member of parliament must be elected from the same population. I would like the courts to seriously consider whether the current law, which has so many electoral districts where the disparity is nearly double, is appropriate."
