There, like I promised: JPY/EUR has risen today. It will rise again tomorrow, and could be quite a big rise. All those who shorted it will be given a weekend full of serious contemplations and reflections. On monday, it will fall, just when those sleepless shorters buy to cover their shorts.
JPY/AUD is not quite following, yet. But it is on notice to rise, maybe even in the coming asian session.
It's more a function of the EUR falling than the JPY rising, and this is primarily a Draghi driven event. Unless you've got some rabbit up your sleeve down under, I don't see how that's going to materialize.
