Japanese Prime Minister Shinzo Abe faces a tough decision on whether to hike the consumption tax to 10 percent next year given the nation's nascent economic recovery, the governor of Tokyo told CNBC on Wednesday.
"The GDP (gross domestic product) figures are going down, [so] it's a very, very difficult question," Governor of Tokyo Yoichi Masuzoe said in an interview with CNBC's Kaori Enjoji.
Japan raised its sales tax to 8 percent from 5 percent in April, a move that's dragged on the world's third-largest economy. The economy shrank an annualized 7.1 percent in the second quarter, revised GDP figures showed on Monday.
Markets are questioning if Abe should forge ahead with a further hike to 10 percent scheduled for October 2015, and risk unraveling the traction in 'Abenomics' – his radical policies to kickstart the economy.
"I think Mr. Abe should decide to raise this [consumption tax] up to 10 percent. But, he has some risks," Masuzoe said, adding that he expects the economy to withstand the effects of the hike.
"As far as Tokyo is concerned, the economy is going up. Given the Olympics games which will be held in six years, Tokyo is working so hard. So we can help pull up the economy," he added.
Beyond reining in Japan's snowballing public debt, which is more than twice the size of the $5 trillion economy, the consumption tax hike can provide Abe with leeway for his pledge to cut corporate taxes to 30 percent from 40 percent to spur growth.
