Japan's economy minister says speculative moves not reflecting fundamentals are not desirable

The economy minister says speculative moves in financial markets not reflecting fundamentals are not desirable

Japanese authorities usually say this sort of thing in two situations:

1. huge volatility
2. &/or the yen appreciating rather too rapidly for their liking

It won't be 1 I wouldn't think … I mean, c'mon dude ….

And as for 2, while the yen strengthened over the Christmas/NY period it has unwound some of that in the past 18 or so hours. Maybe he want's more (I'm certain he does).
