USDJPY is facing the support of the bottom of the price channel on 4-hour chart. As long as the channel support holds, the uptrend from 105.32 could be expected to continue and next target would be at 120.00 area. On the downside, a clear break below the channel support will indicate that the uptrend had completed at 118.97 already, then deeper decline to test 115.45 support could be seen.
