Speaker Mori of the House of Representatives postponed a scheduled vote on a bill to reduce the number of Diet seats on Wednesday.

The delay reflects a deepening deadlock between ruling and opposition parties. The shift in priority underscores the urgency of resolving imperial succession laws before the current legislative session expires.

The decision follows a period of tension where opposition parties reacted against the ruling coalition's attempt to push through both the seat-reduction bill and a separate bill regarding the vice-capital. Speaker Mori said that all parties should work toward the normalization of the Diet to ensure critical legislation is handled properly [1, 2].

Central to the current legislative priority is the amendment of the Imperial House Law. A representative from the Democratic Party for the People said the speaker expressed a strong will that the revision of the Imperial House Law is an urgent issue that cannot be postponed and must be given top priority [1].

While some reports indicated a general agreement to cut 45 seats from proportional representation [4], the formal vote was ultimately delayed to make room for the succession debate. This maneuver comes as the clock ticks toward the end of the session on July 17 [3].

The House of Representatives continues to struggle with balancing administrative reforms and constitutional traditions. By pausing the seat-reduction vote, the speaker aims to prevent a total parliamentary freeze that could leave the imperial succession issue unresolved [1, 2].

Speaker Mori said that all parties should work toward the normalization of the Diet.

The postponement indicates that the ruling coalition is willing to trade immediate administrative wins, such as the seat-reduction bill, for a consensus on the Imperial House Law. Because the session ends on July 17, the window for legislative action is narrow. If the parties cannot normalize relations quickly, Japan risks entering a period of instability regarding the legal framework of the imperial succession.
