Japan's top banker has hinted a shift of policy is on the horizon
Industrial output also rebounded during the month, rising 1.2% in August from July, the government said.

Japan's unemployment rate fell to 4.2% in August, from 4.4% in July, raising hopes that an increase in the workforce could eventually lead to higher consumer spending.
"The unemployment rate crept up last month, but that was because of an increase in people coming into the labour market," said Kaori Yumoto, an economist with Mizuho Research Institute.
"The decline this month reconfirms the improving underlying trend."
Separate government figures showed that spending by households headed by salaried workers rose by 3.2% in August from July.
