USD/JPY is soaring after working through offers between 90.00 and 90.50. The move seems to have more of a macro shift in sentiment than a short-term reaction to firmer US equities today. Like GBP before it, the market sometimes gets tired of pushing a market in one direction and suddenly reverses for no good (fundamental) reason. I suspect that is what is underway at the moment.

90.97 and 91.31 are resistance above the market now that 90.74 has been overcome.
