No, I have not. I assume that any form of Tamatown that is compatible with this Japanese Tamagotchi will probably be in Japanese language, which I am not capable of translating. Its possible that there is a glitch or workaround on the English site, but I don't know and haven't heard anything about it. In fact, I have not used the English site for the American V5 at all, so I don't know if a Japanese Version would utilize the same features.
