Nikkei 2.6% higher

A weaker yen helped Japan's benchmark index bounce off the previous session's six-week low. Dollar-yen rose above the 97 handle but still remains nearly 3 percent lower from a high of 99.9 hit earlier this month.

News of corporate tax cuts helped boost sentiment. The Nikkei newspaper reported that Abe has called for a study on lowering the current corporate tax rate as a way to attract foreign-capital and boost growth in an attempt to offset the impact of a sales tax-hike.

"It seems logical that traders have been a little surprised by the timing of the potential cut, and seems to back the idea that an increase in sales tax in April 2014 is looking promising; although we feel the real risk is it comes out in 1 percent increases over five years, as opposed to a two-tiered strategy," wrote Chris Weston, market strategist at IG.
