OSAKA – Japanese opposition party Osaka Ishin no Kai decided Tuesday to change its name by removing "Osaka," as the party tries to gain wider support from across the country. The party, which has its base in Osaka Prefecture, made the decision at a meeting of its executives in the city of Osaka. It will formally adopt a new party name at an extraordinary party convention to be held in the city on Aug. 23. In Sunday's election for the House of Councilors, in which half of the chamber's 242 seats were contested, Osaka Ishin won only seven seats -- three in prefectural constituencies and four under the nationwide proportional representation system. The three constituency seats it won are in Osaka and neighboring Hyogo Prefecture.
