Emerging differences between the Liberal Democratic Party and the Japan Innovation Party over how to implement an agreement that reduces parliamentary seats could strain the ruling minority coalition¡¯s unity and test its ability to compromise.

An Oct. 20 agreement between the two parties included a promise, at the insistence of the JIP, to introduce legislation in the current parliamentary session that cuts the number of Lower House seats by 10%, and to aim for its passage.

There are currently 465 Lower House members, and a 10% reduction would mean about 50 fewer seats. The agreement doesn¡¯t specify whether the cuts should be made in the 289 single-seat district seats or the remaining 176 proportional seats.
