Me and a Japanese friend were talking about this the other day actually.
Japanese Yen Rate Forecast
Dollar reduce it value against japans yen.
Exchange rates are a tricky thing... When I came to France from England a couple of years ago to study, I was living it up with the exchange rate. I thought things could only get better, so I didn't exchange all my money. Now, I'm losing so much whenever I exchange that I've basically gotta find a job soon or get a loan to finish my studies! These things happen, and you just gotta get through it!
