Bank of Japan Gov. Masaru Hayami reiterated Wednesday that the state of the economy and price trends will guide the BOJ's decision on whether to revive its "zero-interest-rate" policy and implement quantitative monetary easing.

Hayami's latest comments in a speech in Tokyo come amid calls by some coalition politicians for the BOJ to revive the policy and implement quantitative monetary easing to help the nation's fragile economic recovery.

Hayami said a decision on quantitative monetary easing "depends on our judgment of the economic situation and price trends."
