Jay Leno gets a taste of Tokyo's nightlife and meets the local Nissan GT-R club. Mr. Leno has the chance of driving the GT-R on its home turf, and he seems really impressed by the car. Currently, the GT-R is the most powerful supercar built in Japan, and apparently, it's the pride and joy of every Japanese car enthusiast. Jay’s host in Tokyo is Sam Mitani, who is one of the journalists who introduced the GT-R on the U.S. scene.
