Overview
- The coalition agreed to reduce seats elected from both single-seat constituencies and proportional representation in the House of Representatives.
- The bill will include a clause that automatically enacts a total 10% cut if a detailed cross-party plan is not finalized within one year.
- Negotiations are anchored to a baseline reduction of 45 seats, comprising 25 from single-seat districts and 20 from proportional lists.
- The parties intend to submit the bill as early as this week and are seeking enactment during the current extraordinary Diet session.
- Passage will require opposition cooperation because the ruling camp holds only 233 seats in the lower house and lacks a majority in the upper house.
