Nautiljon is a French multimedia portal for fans of East and Southeast Asian entertainment and culture. Its extensive community-driven database and news coverage span anime, manga, dramas, Asian films, video games, music, artists and personalities. Visitors can explore character profiles, release calendars, episode schedules, lyrics, music videos, albums, soundtracks, conventions, cultural traditions, recipes and image galleries. The site also covers books and collectibles, including art books, light novels, photobooks, DVDs, Blu-rays and other merchandise, and provides practical directories for shops, restaurants and retailers.

Nautiljon combines reference content with an active community offering forums, reviews, quizzes, polls, contests, member pages and classified listings. Members can create and update entries, add images, lyrics, news and reviews, and help correct or complete existing records. Contributions are reviewed before publication. A free account is required to participate, while readers can browse articles and discover recommendations through the site’s discovery feature. Nautiljon presents itself as a platform written and enriched by its members rather than by an in-house editorial team.
