Some Bank of Japan policymakers think the recent rise in consumer prices is likely to slow, and there are calls to provide a thorough explanation of how the BOJ intends to achieve its 2 percent inflation target, the minutes of their November policy meeting released Thursday said.

"One member pointed to the possibility that it might take some time until the narrowing of the negative output gap is reflected in prices, and that the pace of the increase in inflation expectations might become moderate," the minutes of the central bank's Nov. 20 to 21 meeting said.

Another said the year-on-year rises in the consumer price index "would gradually lessen" in pace, the minutes show. It also said one member was "closely monitoring" whether Japan can continue to see inflation rise amid a global deflationary trend.
