USDJPY is very close to a current daily high. To catch a pullback from the underlined red area, monitor a 4H time frame.
I see a nice rising channel there. Its support breakout (4h candle close below) will give you a strong bearish confirmation. A bearish movement will be expected to 150.9 level then.
Alternatively, a bullish breakout of the daily resistance will push the prices to 151.9 level.
