On the weekly this FX pair has been in a downtrend for many weeks, on the daily the USDJPY has been barely tradable. Sometimes the higher timeframes just prove to have the smoother trend. Apply it to your style of trading.
Hold on to USDJPY shorts, next support at 105 and 100 will follow.
May actually not hit 105, I dont know. Overall this is a reaction, therefore the trend on this TF is choppy. Who knows when this will bounce back up into balance zone and turn back to be a long.
