"There is no better opportunity than now to completely get out of deflation. Talking about the limits of monetary policy does not help at all," Kuroda said in a speech to business leaders in Osaka, western Japan.

The BOJ made an abrupt shift last week to targeting interest rates on government bonds to achieve its elusive inflation target, after years of massive money printing failed to jolt the economy out of decades-long stagnation.
