Mike had the response from Japan's finance minister Aso over the weekend "US monitoring will not constrain Japan on FX" (yeah, I bet what he really said was a bit stronger than that, thankfully we'll never know, as ForexLive is a family website and I wouldn't like to post up such language :-D)

Check out Mike's post from more (link above) and Bloomberg have more here on the US concerns.
