What do you think would be the most appropriate yen-dollar rate for the Japanese economy, as a whole?

110.00

120 was good

Whatever the market says. My guess is it will go to somewhere closer to 200 before ll the money priniting is over.

@Wakarimasen: Sadly, the market doesn't always do the 'right' thing for the Japanese Economy, which was the question. It may well go to 200 (but I think there would be intervention LONG before then), but not many of us will be able to afford our energy bills at that level. Let alone imported cars, food etc. The market 'said' it was 75 in 2011. That was NOT good for the Japanese economy.

The Yen at 140 was very good - but if they really want to get the economy on the ball - make the Yen 200 - why not give China some real competition ?

I like it at 80, that my selfish answer. Cheap imported food, wine, fuel, etc and cheap trips abroad.

@meguroman: Of course, from a selfish point we'd all agree with you :) But, if you are looking for a little longevity in employment, then you know its better higher!

250 is fine with me.

I would say 120-130 ball park.

¥95-100
