With the overnight high just shy of 81.50 there is chatter around of good size USD/JPY to sell at 81.50 , layered up to 81.80.
On the day, 81.00 is said to be critical support for the short-term, though a quick glance at the charts would seem to suggest 80.90/95 is more important.
Be interesting to see how market reacts from 81.50/80 if Abe opens his gob again.
