USDJPY stays below a downward trend line on 4-hour chart, and remains in downtrend from 84.17. As long as the trend line resistance holds, the price action in the range between 81.55 and 83.38 could be treated as consolidation of the downtrend, and one more fall towards 81.00 is still possible. On the other side, a clear break above the trend line will signal completion of the downtrend, then further rise could be seen to 83.80 area.
