I BELIEVE that this pair will make its way back down due to a couple of reasons.
First would be the dollar which has lost its power over the last couple of weeks which puts USDJPY in a chokehold.
Secondly would be the FVG imbalanced level(Green box drawn) that the USDJPY has touched on the 4 hour which i would recommend waiting on a BOS on the 1 hour for confirmation on further down movement
Lastly would be the fib retracement that is touching the last possible level it could touch(0.618) before possibly the retracement is finished
This isnt financial advice
