Japan Supreme Court finds 2025 upper house vote disparity unconstitutional
Japan’s Supreme Court ruled on the vote gap in the July 2025 upper house election on Wednesday.
Voters in some parts of the country had up to 3.13 times the voting weight of voters elsewhere.
The court said the disparity put the election in a state of unconstitutionality, but it rejected requests to cancel the results.
Japan had previously reduced gaps by combining pairs of less-populated prefectures into constituencies, and the court had upheld disparities in the 2016, 2019 and 2022 elections.
The judges said efforts by parliament to reduce the gap had stalled, making the disparity hard to ignore.
The ruling raises concerns about equal voting power, but it does not change the 2025 election results.
Japan’s Supreme Court ruled that the vote-value gap in the July 2025 upper house election was in a state of unconstitutionality.
The maximum disparity was 3.13 to 1, the court said.
The court dismissed requests to nullify or invalidate the election results.
It said efforts by parliament to reduce vote disparities had stalled.
The ruling followed conflicting decisions by lower courts, most of which found the disparity unconstitutional.
