The Liberal-Kokuto Party increases its seat share, calculated based on a proportional decrease of 31 seats in the House of Representatives.

Regarding a bill by the Liberal Democratic Party, Japan Restoration Party, and Democratic People's Democratic Party that would reduce the number of proportional representation seats in the House of Representatives by 31, Jiji Press calculated the number of seats each party would gain based on the results of the February House of Representatives election, and found that the three parties and the Communist Party had a slight increase in their share of seats. In terms of proportion, the Liberal Democratic Party decreased by 4.6 points, while the Democratic People's Democratic Party increased by 1.5 points.

House of Representatives reduced by 31, bill submitted; Liberal-Kokuto aims to pass in the current Diet session

The estimate is to reduce the proportionality constant from the current 176 to 145 and integrate the Chugoku and Shikoku blocs. In addition, the seat allocation system was changed from the previous ``D'Hondt system'' to the ``modified Sanlag system,'' which is said to be advantageous to small and medium-sized parties. They focused only on the seats they had originally won, and did not take into account the fact that the Liberal Democratic Party, which won by a landslide in the House of Representatives election, had lost seats to other parties.

According to the results, the Liberal Democratic Party lost 21 seats to 60, the Centrist Reform Alliance lost 5 seats to 30, Team Mirai lost 2 to 9, and the Ishin, Democratic People's Democratic Party, and Participating Parties lost 1 to 12, 17, and 13 seats each. The Communist Party remained in four seats.

The proportional share rate decreased only for the Liberal Democratic Party. In addition to the People's Democratic Party, the increase was 1 point for the Suffrage Party, 0.9 point for the Meiji Restoration, 0.8 point for the Centrist Party, and 0.5 point for the Communist Party, leaving the future unchanged.

However, looking at the overall number of seats, the weight of single-seat constituencies where the number of seats was maintained increased, and the Liberal Democratic Party increased by 0.2 points. Meiji Restoration, National Democratic Party, and Communist Party also increased by 0.3 points, 0.2 points, and 0.1 points, respectively.

On the other hand, centrists who did not increase their seats in the constituency decreased by 0.5 points. New political parties that emphasize proportionality were also offset by the effect of the modified sunlag formula, with Mirai decreasing by 0.3 points and suffrage remaining unchanged.
