Sankaku Complex

Sankaku Complex (sankakucomplex.com) is a long-running anime and hentai imageboard and news aggregator originating from Japan. It combines a booru-style image gallery, where users tag and share anime and manga artwork, including explicit material, with a blog section covering Japanese pop culture, anime news, and media.

The basic gallery is free to browse without an account. Some features, such as removing image limits, disabling ads, or accessing certain filtered content, require a paid membership. The free tier is functional but limited in how many pages or results you can view per session.

Sankaku Complex is a well-established site with a large community. Risks are mainly ad-related on the free tier. Be aware the site hosts a wide range of content including some that may be deeply offensive to many users; you need to configure content filters to exclude material you don't want to see.

It uses a booru tagging system: images are uploaded by users or pulled from sources and annotated with detailed tags covering characters, art style, rating, and content type. You can search by combining tags to find specific characters, artists, or content categories. The news section is separate from the image board.

User-uploaded artwork on imageboards frequently includes fan art based on copyrighted characters, which the rights holders have not authorised. This is broadly tolerated across the anime fandom but is not formally legal. The site's content policies prohibit real-person non-consensual content and imagery depicting minors, though enforcement is imperfect.
