Bank of Japan Gov. Haruhiko Kuroda endorsed on Thursday government plans to compile a fiscal spending package for disaster relief and measures to help the economy stave off heightening global risks.

The challenges posed by a string of recent natural disasters and the potential hit to the economy from slowing overseas growth "should be better addressed by government with fiscal policy and structural policies," Kuroda said at a seminar.

"At the same time ... fiscal space for the Japanese government is somewhat limited, so wise spending is required," he said.
