Yes, I know that Japan is a country not a city. Kimbo, not so much.
Kimbo was in Japan to commentate ringside at the K-1 Grand Prix finals. A couple of times he referred to Japan as a city. No biggie. It happens to a lot of American tourists. I think it's something in the wasabi.
Here's a pic of Kimbo and his manager Icey Mike arriving in Japan. Pic is courtesy of Sports Navi.
