im not sure but i think the japanese one uses a different voltage but then again i could be wrong.
if anyone knows if it would work it will be greatly appreciated
From what I understand there are 3 different power supplies (voltage wise) it depends on which voltage yours needs. I have a rather low seriel US aes (14xxx) and it requires a 5 volt power supply. You can pick up a generic mulitivolt one at Radio Shack for cheap and it'll work just fine.
