See the post at http://www.exchange2000.com/~wsapi/investor/s-15208/reply-54. Japan has a very large trade surplus with the U.S., and April figures show the surplus doubled. U.S. is expected to push for measures to cut this surplus at the G7 meeting commencing June 20. The fastest way to reduce the imbalance in the amount of goods the Japanese sell to the U.S. versus the amount they buy is to reduce the buying power of the yen/increase the buying power of the dollar. In expectation of these measures plus the possibility of a narrowing of U.S. versus Japanese interest rates (Japanese going up, U.S. possibly staying the same for a while), the exchange rate is dropping i.e. it is taking fewer and fewer dollars to buy a yen. There is often enlightening commentary on the yen vs. U.S. dollar exchange rate at http://www.nikkei.co.jp/enews/. Good luck.
