Following yesterdays chart and looking through the timeframes. It is possible that the USDJPY is running out of steam for now. There are many reasons here for a pull back:
RSI overbought on 4HR 1HR chart resisting further upsdide Trump and his general behaviour Upside rejection developing on daily chart Approaching end of the month - Profit taking 6 days of straight gains without consolidation or pull back
This is potentially a good combination for a short scalp followed by a longer term long entry setup
