Sponsorship and Advertising

Altonimbus Entertainment is proud to present Kumoricon, the largest anime, manga, and Japanese culture convention in Oregon. Altonimbus is an Oregon nonprofit corporation, dedicated to creating an environment for fans of anime, manga, and Japanese culture to share and learn from one another. ANE'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. With over 7,000 members in attendance at Kumoricon 2017, the staff have high expectations for Kumoricon 2018. Arguably the largest step in Kumoricon's 16-year history, the convention moved back to Portland in 2016, hosted in the beautiful Oregon Convention Center. Kumoricon 2018 will take place October 26 - October 28, 2018, just in time for Halloween festivities.

Moving towards our largest event yet, we greatly value our previous sponsors' continued support, and the new relationships we hope to build with new sponsors and advertisers. Our 2018 sponsorship and advertising packet will be available soon. If you have any questions, please email our Industry Manager ( We look forward to working with you to host the best Kumoricon to date.
