According to an on-line article I just read, electrical voltage in Japan is @ 100 VAC vs 120 VAC as used in the USA. Also in Tokyo, the cycles are 50 Hertz per this article and not 60 hz as in the USA. But what you want to do is check the specs on the electrical power supply of this particular component you want to purchase. It's certainly possible that Yamaha could produce two differnt units, one for use in Japan and one for export to the USA. It's very possible the Japan unit may not work correctly here. Just be careful and check this out thoroughly before having it shipped here. You never know.
