"The Bank of Japan argues that, "Japan's economy is likely to continue expanding and maintain growth at a pace above its potential, mainly through fiscal 2018, on the back of highly accommodative financial conditions and the effects of the government's large-scale stimulus measures, with the growth rates in overseas economies increasing moderately.”
