USDJPY failed to break below the bottom support trend line of the price channel on the 4-hour chart, suggesting that the pair remains in the uptrend from 104.63. Further rise could be expected and a breakout of 110.03 resistance could trigger another bullish movement towards 112.00. Key support is now at 108.64, only a breakdown below this level would indicate that the upside movement had completed at 110.03 already, then the pair would find next support level at 108.00.
