USD/JPY dropped to as low as 104.63 last week and the break of 105.24 support confirms resumption of decline from 114.73. Such decline is viewed as the third leg of the medium term pattern from 118.65. Initial bias remains on the downside this week for 104.20 projection level first. Sustained break there will pave the way to 98.97 (2016 low). On the upside, break of 106.63 resistance is needed to indicate short term bottoming. Otherwise, outlook will remain bearish in case of recovery.
In the bigger picture, medium term down trend from 118.65 (2016 high) is still in progress and extending. Build up in downside momentum argues that it might be extending the whole corrective pattern from 125.85 (2015 high). 100% projection of 118.65 to 108.12 from 114.73 at 104.20 will be a key level to watch as firm break there could bring downside acceleration. And in that case, 98.97 key support level (2016 low) would at least be breached. This bearish case will now be favored as long as 108.12 support turned resistance holds.
In the long term picture, the rise from 75.56 (2011 low) long term bottom to 125.85 top is viewed as an impulsive move, no change in this view. Price actions from 125.85 are seen as a corrective move which could still extend. In case of deeper fall, downside should be contained by 61.8% retracement of 75.56 to 125.85 at 94.77. Up trend from 75.56 is expected to resume at a later stage for above 135.20/147.68 resistance zone.
