Yukio Edano, founder and president of the Constitutional Democratic Party of Japan, is taking the spotlight ahead of the general election.

The CDP, just two weeks old, is expected to become the second-largest opposition force after Sunday's election, media projections show. It is gaining great momentum from liberal voters who find themselves running out of options.

According to the latest forecasts, the conservative Liberal Democratic Party led by Prime Minister Shinzo Abe appears headed for a landslide victory as the conservative Kibo no To (Party of Hope) loses steam from disillusionment with Tokyo Gov. Yuriko Koike's publicity stunts. The upstart party was initially expected to be a powerful challenger after Koike’s success in the Tokyo Metropolitan Assembly election.
