USDJPY is testing 100.75 support, a breakdown below this level will indicate that the long term uptrend from 75.57 (Oct 31, 2011 low) had completed at 105.44 already, then deeper decline to 97.00 area could be seen. On the other side, as long as 100.75 support holds, one more rise to 110.00 area is still possible.
