WASHINGTON, Oct 7 (Reuters) - Bank of Japan Governor Haruhiko Kuroda said on Friday it was difficult to achieve balanced economic growth with monetary policy alone.

Kuroda said there has been a shared understanding among Group of 20 major economies that policymakers must use monetary, fiscal and structural policies to achieve balanced economic growth.

"I don't think there was a strong feeling shared among (G20 nations) that monetary policy was reaching its limits or that an over-reliance on monetary policy was causing big problems," he told a news conference.
