Oops. That's problematic now, isn't it? Hold on a sec, though. Japanese current is 100 V, while North American current is 120 V, which means that if you plugged your Japanese-made, Japan-bought cordless phone in your North American electric plug, you'd fry the power source of the phone. In other words, unless you by a voltage converter, your phone is useless. So, just as I thought, you'll have to buy domestic. I unfortunately can't help you there. Have you tried checking the Web sites of know Japanese makers, such as Panasonic, Sony, etc.?
