USD/JPY's recovery from 79.58 is still in progress and might extend further to 4 hours 55 EMA (now at 81.16) and above. But after all, break of 82.76 is needed to signal short term bottoming. Otherwise, outlook will remain cautiously bearish. Below 79.58 will bring another decline to retest 76.40 spike low.
In the bigger picture, persistent weakness in the pair after hitting 85.51 dampens the bullish view that an important bottom is formed at 76.40. Also, note that strong resistance has been seen from the falling 55 weeks EMA and long term falling trend line. That is, there is no confirmation of reversal yet. The break of 80.50 support indicates that rebound from 76.40 was likely just a correction and the long term down trend is still in progress for another low below 76.40.
