Bank of Japan policymakers agreed that the amount of government debt purchases will fluctuate under its quantitative easing program, minutes of the central bank's April 26-27 policy meeting showed on Wednesday.
Members also said such fluctuations do not pose problems for the BOJ's guidance on its market operations, the minutes showed.
Policymakers also expressed more optimism about exports and industrial production, according to the minutes.
The BOJ kept monetary policy on hold at the meeting and offered its most optimistic assessment of the economy in nine years. The BOJ also trimmed its consumer price forecast as inflation expectations have struggled.
At a subsequent meeting on June 15-16 the BOJ upgraded its assessment of consumption but ruled out an early exit from quantitative easing.
