im not so sure that is japan......unless in japan there are yellow and blue signs that look EXACTLY LIKE the ones i see here in the states, called NAPA. im shocked no one else saw this.
I did talk to a guy on the street that traveled alot to japan on business, and he said that he saw a GN in Japan once, and he talked to the guy with it and said he had bought it from an american business man in the mid 90's. The GN is bone stock and was sold to Japan guy for 50,000. But i have no way to confirm this.
That sign in the backround is so the napa sign!!!
