Potential USDJPY short - Ichimoku and Williams %R confirmation

Potential short on USDJPY, breaking out of the Ichimoku cloud and awaiting close with Chikou below price and Kijun & Tenkan confirmation. 75 period Williams %R below the 50 SMA, I use this on most of my algo based trades as a confirmation of the trend bias. Also dollar looking weak after 4.8% fall in GDP during first quarter.
