A Bank of Japan policymaker said there is a need to further ease monetary policy to emphasize its commitment to the central bank's 2 percent inflation target, a summary of opinions from the June policy meeting said Friday.

There was a contradicting view, however, with one policymaker arguing the BOJ should change the current policy framework from one of achieving the target within a short period of time to one that is "suitable for a protracted duration."

At the meeting from June 15 to 16, the central bank refrained from further monetary easing despite a year-on-year drop in consumer prices in April. The yen climbed against the U.S. dollar and stocks plunged following the decision.
