Ueda told parliament on Friday that corporate price-setting behaviour was showing changes that could work to push up inflation more than expected.
While the BOJ will not produce fresh inflation forecasts next week, it may signal that inflation is overshooting initial projections - possibly at Ueda's post-meeting briefing, the sources said.
"The BOJ must be vigilant to both the risk of an inflation overshoot, and the risk of a deep overseas slump hitting Japan's economy."
With droves of companies continuing to hike prices, the BOJ is widely expected to upgrade its inflation forecasts at its next quarterly review in July, analysts say.
