I agree. That's the only picture I could find of someone that claims to be Ainu. I've seen others that don't look asian at all.
I've read some speculation that the original Samurai were these tall, hairy and light skinned people and that they were the original 'royals.' ...and, that the Japanese custom of 'white face' was the Asian types way of emulating the appearance of the royals. Also, there are supposedly ancient paintings of the Samurai that depict these people and the Japanese keep these paintings in hiding. Even so, I've seen pictures of Samurai with full beards and real hairy leggs.
Try this one. I can't post it because it's copyrighted:

Realize that there are very few full-blooded Ainu left. They are vanishing through interbreeding with Japanese. Consider how few full-blooded African blacks remain in the U.S. or South America, and how often they exhibit mixed-race physical features.
The web site where you found the images of the Count and the Tocharians is...um...interesting. Given its rather obvious bias I'm inclined to give its objectivity a lot of Kentucky windage. But even it agrees with my point that the Ainu are called "hairy" only in contrast to the rather hairless Japanese.
