The leader of Your Party said Sunday that he will consider joining forces with the new party to be launched by Tokyo Gov. Shintaro Ishihara.

"I want to hear Mr. Ishihara's strategy for defeating centralization of power," Yoshimi Watanabe said on a television program. Watanabe had apparently been lukewarm about collaborating with Ishihara.

Watanabe said cooperation is possible as long as the parties' key policies and principles are compatible.
