Resistance for the USDJPY is at 100.50 / 101; which is the November 4 high / 61.8% of the decline from 110.71. RSI is rolling over from above 70, which warns of a top. Still, short term structure suggests that one more is needed before a more permanent top is in place. Expectations this week are for a push above 100. 101-103 is the reversal zone.
