That might not be a common view, yet I believe USDJPY is back to the uptrend now. Support line of 100 seems to be really well defended and each time after it is attacked USDJPY makes higher highs. I believe the pair will go up to about 106 level as it is close to fibo 261,8%.
On the longer time period (here shown on daily, though 4h chart shows it even better) it looks like downtrend is going to reverse. After trying to break the descending downtrend line retracements tend to be really strong…
