4chan is a simple image-based bulletin board where anyone can post comments and share images. 4chan's collaborative-community format is copied from one of the most popular forums in Japan, Futaba Channel. Different boards are dedicated to different topics, from Japanese anime, manga, and culture to videogames, music, and photography. Users do not need to register a username before participating in the community. Feel free to click on a board that interests you, and jump right in—anyone can contribute!
