On the 1-hour chart, USD/JPY has just broken through the important resistance zone at 154.50-154.80 and is retesting it as potential support. The current upside momentum is supported by both the 34 EMA and 89 EMA, with the 34 EMA acting as the nearest support.
I expect USD/JPY to continue rising in the coming session. The price is likely to test and surpass 155.00, with a short-term target at 155.50.
