Moves to launch a new party have emerged among three opposition parties in Japan, sources said Sunday.

The idea arose in the course of talks on the possible integration of the Constitutional Democratic Party of Japan and Komeito into the Centrist Reform Alliance.

The CRA and Komeito are keen about the new opposition party option. Some senior members of the CDP and officials of a major labor union supporting the initiative are also positive, according to sources familiar with the matter.
