Comiket 70

Comiket is a bi-annual event that is held at the Tokyo Big Sight convention center in Japan. It's the world largest comic convention. Otakus come from all over Japan and around the world for this event to get a chance to buy doujinshi and other anime and manga related items.

Here's a Youtube link of Comiket 70, which was held from 11th - 13th August 2006. I was curious as to how far otakus in Japan would go... and now I know. O_O
