USDJPY remains in uptrend from 79.69, the price action from 81.26 is treated as consolidation of uptrend. Support is at the uptrend line on 4-hour chart, as long as the trend line support holds, we'd expect uptrend to resume, and one more rise to 81.60-81.80 area is still possible. However, a clear break below the trend line will indicate that the rise from 79.69 had completed at 81.26 already, then the following downward move could bring price to 78.00 zone.
