Yep, just Drift teks....
I've been to Omori factory 3 times now, first time was about 3 years ago, and they had the showroom right at the front. Was quite good, lots to look at, but then they moved it into a kinda side room, and they only have a limited supply of stuff, i think you have to order stuff from them, cant just get it right then and there.
Shinagawa is the main station to get to, which is a pretty big station, and easy to find on the toyko rail map, then change at shinagawa, cant remember the line, but Omori kaigan is the station you want, its only 2 or 3 stations away. You cant miss the Nismo sign!
