USDJPY stays below a falling trend line on its 4-hour chart and remains in short term downtrend from 114.73. As long as the price is below the trend line, the downtrend could be expected to continue and deeper decline to test 112.95 support is still possible. A breakdown below this level could take price to next support level at 112.65, followed by 111.65. On the upside, a clear break above the falling trend line will indicate that the short term downtrend is complete, then another rise towards 114.73 previous high could be seen. Above here would aim 115.50 key resistance.
