I'm skeptical of this. It looks from the picture that this person collects Xbox 360s. If you collect them then a Japanese one is essential to get those Japanese exclusives. I think that this is someone that doesn't live in Japan with a large collection of Xboxes, one of which is from Japan.
So until this Photo has a Japanese guy standing next to it with a sign saying "I own all of these, I'm that sad" I'm remaining a skeptic.
