Recently Asahi News reportedly the following:
About 50 shops in the shopping street at Fussa City of Tokyo that was adjacent to the U.S. military Yokota base had started service that enabled shopping using the US dollar. The English flag was flied for the 10,000 American soldier and family members. In the street that line up with imported goods general stores, the procedure to exchange for yen was ridded, and thus could come to the store readily. It was full of wishes that it became the advertisement for the "town of the base" that depended on the increasing American customers for survival. It was said that there were a lot of Americans who completed their shopping within the base compound because of the yen's sharp rise against the dollar recently. For that purpose, Japanese guests were also called on "to shop using the US dollar taken home from traveling abroad".
The increase in the value of yen has made retailing business in Japan more difficult.
