USDJPY playing a dangerous game at 123.30

It looks like we're already in FOMC mode in USDJPY

USDJPY has been playing a tight range today but we keep coming back close to the 123.30 level and that could be a worry

USDJPY 15m chart

EURUSD has just tested and broken its upper range and so has the pound. If that move continues then this 123.30 level is likely to come under renewed pressure, and you know I don't like it when a level gets tested often in fairly quick succession

Should we break through then some mild support is likely at 123.20 and then at the Asia opening lows around 123.10
