The market has been trying to get bullish on USD/JPY for the last few weeks but the overall range-trading bias seems to be winning the day again. I suspect that the speculative market is still long USD/JPY and some of the JPY crosses, and seeing as its Friday (usually risk-off in Asia) we may see a stop-loss hunt on the downside.
103.50 is the first level of support in USD/JPY and 136.30 is the first level of support in EUR/JPY.
