Famous in Japan?

The other day I was watching a show about strange and unique world records people had achieved, and there was a segment featuring Takeru Kobayashi, the renowned competitive eater who won the World Hamburger Eating title over the weekend (congratulations!). It was cool to see him getting some love from Japanese television, since he's almost completely unknown here in Japan for some reason, although he has lots of fans outside of Japan. To many who grew up in the Nintendo era, Mario and Donkey Kong creator Shigeru Miyamoto is a familiar icon, yet he's almost completely unknown over here, and even J-List's Yasu, a hardcore old-school gamer with a large collection of classic NES game cartridges, did not know his name or face since he's not part of the popular culture here. Some other examples of Japanese whose stature is larger outside of Japan than in include Takashi Murakami, the unique artist who has brought his colorful anime-influenced themes to the international design world; Heroes star and super-geek Masi Oka; artist Yoshitomo Nara; and the Japanese band Shonen Knife.

He created some of Japan's most famous cultural icons, but Miyamoto-san is unknown here.
