Japan's ruling parties agreed Wednesday to postpone deliberation on a bill to reduce the number of House of Representatives seats until the next Diet session [1].

The delay reflects a deadlock between the government and opposition parties over the timeline and conditions for the vote. Because the current session ends July 17 [2], lawmakers lacked a viable path to pass the legislation before the deadline.

Kajiyama, the Liberal Democratic Party's (LDP) director of committee affairs, reached the agreement with Shigenori Shigetoku, the director of committee affairs for the Japan Innovation Party [1]. The decision follows a series of meetings between Prime Minister Takaichi and party representative Yoshimura [3].

Opposition parties had conditioned their support on a guarantee of intensive deliberation. This friction made it impossible to secure the necessary consensus before the session closed [2].

"I responded by saying that we would make the maximum effort," Kajiyama said [1].

The proposed legislation targets a 10% reduction in the total number of seats in the lower house [2]. While there is general agreement on the scale of the cut, the specific method of implementation remains a point of contention.

LDP Secretary-General Suzuki said the party's internal preference is to achieve these reductions through proportional representation seats [4]. This approach seeks to minimize the impact on individual constituency boundaries, though it requires further coordination among party members to finalize.

The postponement highlights the difficulty the Takaichi administration faces in balancing a mandate for smaller government with the political realities of seat distribution. By pushing the debate to the next session, the LDP avoids a high-profile legislative failure on July 17, but it also delays a key structural reform that has significant implications for how proportional representation and single-seat districts are weighted in future elections.
