Tokyo’s Comiket, not Comic-Con, is the biggest fan convention in the world
From August 10-12, around 500,000 people will gather for for the 94th Comiket (also know as the Comic Market).
Held at the Tokyo Big Sight venue, the biannual Comiket is the biggest fan convention in the world. But this is no corporate marketing extravaganza.
Comiket is a celebration of doujinshi, Japanese for self-published comics, novels, and magazines. The convention is a not-for-profit, and run by volunteers.
