Prime Minister Shinzo Abe vowed Wednesday to ensure the Liberal Democratic Party-New Komeito ruling bloc recaptures control of the Upper House in the July election, bringing an end to the divided Diet.

Boasting the achievements of his "Abenomics" economic policies, which, other than the Bank of Japan's massive monetary easing and vast purchases of Japanese government bonds have been basically verbal efforts to talk up the economy and talk down the yen, Abe pledged that if his ruling bloc can dominate both chambers of the Diet, politics will become stable.

"Every year a prime minister has been replaced, including me, and the national strength of Japan has considerably been damaged," Abe told reporters to mark Wednesday's close of this year's regular Diet session. "You need to put an end to this divided Diet."
