The USD/JPY pair has broken its upward trend line on a 30 minute time frame. This shows a weakness for the uptrend. The upward trend line may act as a resistance now. However, the pair is trading above the 50 day moving average (shown in green) and below the 100 day (shown in yellow) moving averages which confirms that the bulls are losing their control. The volatility for the pair is low, as the price is trading within the Bollinger band and close to its 20 day moving average.
The RSI is trading in line with the price action which means that the bias could be to the upside.
