As was popular some years ago with Japanese women, my girlfriend is telling me she's thinking about buying USD as the Yen is simply too strong and the dollar too weak to pass the opportunity up. Historically the yen is about 110 ish per dollar, but at the monent sits at around 81. Is there any particular not to do this? She thinks the government is is going to be taking action to raise the value of the dollar. To me it seems fairly benign as an investment. I can't really foresee the exchange rate becoming any less favorable than it is now, but I'm no expert (famous last words).
