Japan's largest opposition party appears to be in danger of falling apart, as some of its core members prepared Thursday to officially demand that their leader dissolve the party and create a new force with Ishin no To (Japan Innovation Party).

Democratic Party of Japan policy chief Goshi Hosono and former President Seiji Maehara held talks with former Ishin President Kenji Eda on Wednesday night and agreed to work for the dissolution of the two parties and the formation of a new opposition force powerful enough to challenge Prime Minister Shinzo Abe's Liberal Democratic Party in next summer's Upper House election.

Maehara is set to put the demand to DPJ President Katsuya Okada "sometime soon," according to Kyodo News.
