You could always use one of the Japanese auto manufacturers. Almost all of them do business internationally. Honda is in Minato, Nissan is down in Kanagawa, Toyota's in Aichi, and Subaru is a bit further away in Gunma. When I was in Japan the first time, I made a presentation on Subaru, but I was unable to actually visit the plant because we were way down in Hirakatashi at Kansai Gaidai and that would've been one heck of a long train ride. Good luck, whatever you decide.
