TOKYO, August 29 (Reuters) - Support for Japanese Prime Minister Shinzo Abe edged above 60 percent for the first time in almost two years, and nearly the same percentage want him to stay in the top job until Tokyo hosts the Summer Games in 2020, a media survey showed on Monday. Voters, however, were split over the premier's "Abenomics" growth recipe of hyper-easy monetary policy, fiscal spending and promised reforms, with 47 percent giving a thumbs down to the Bank of Japan's negative interest rate stance, the poll showed. Support for Abe's cabinet hit 62 percent in the Aug 26 to 28 survey by the Nikkei business daily, up four points from earlier this month. The paper suggested the rise could be due to Olympics fever, after a closing ceremony in Rio de Janeiro where Abe appeared dressed as popular video game character Mario.
