USDJPY - Awaiting for more confirmation for bullish bias

Nice 1 - 2 wave, down trend top line has been broken, not so much volume as I would like. I'll go long if it stays above the trend line.
Note: other JPY pairs e.g. EUR, AUD and GBP (in a lesser degree) are presenting the same pattern, it's as if the yen is ready to go lower?
