USD/JPY is stuck right in the middle of its medium-term consolidation so its pretty hard to get overly excited at current levels. Nevertheless, with some of the crosses like GBP/JPY starting to make interesting technical moves, the Yen bears will probably be hopeful that another bout of easing from the BOJ might get the market moving.
Risk-reward would seem to favour the USD/JPY bulls but be warned, the market will be somewhat long and there will be a stop-loss run if the BOJ disappoints.
