Sponsorship and Advertising

Altonimbus Entertainment is proud to present Kumoricon, the largest anime, manga, and Japanese culture convention in Oregon. Altonimbus Entertainment is an Oregon nonprofit public benefit 501(c)(3) organization, dedicated to creating an environment for fans of anime, manga, and Japanese culture to share and learn from one another. Altonimbus Entertainment’s primary event, Kumoricon, is the annual gathering and realization of this commitment.

As the oldest anime convention in Oregon, Kumoricon is an opportunity for people of all ages to explore and share their enthusiasm for Japanese media and Asian culture. Kumoricon has been hosted in the beautiful Oregon Convention Center since 2016, and has reached the 10,000 paid members milestone as of the 2019 event. Kumoricon 2026 will take place November 13–15, 2026.

We greatly value our previous sponsors’ continued support, and the new relationships we hope to build with new sponsors and advertisers. Our 2026 sponsorship and advertising packet will be available closer to the convention. If you have any questions, please email our Industry and Sponsorship Manager. We look forward to working with you to host the best Kumoricon to date.
