With the ink barely dry on HBO Max’s deal to bring BritBox content to their platform, the streamer has announced that they’re upping their partnership with Toho-owned Japanese animation distributor GKIDS.

Already the exclusive home of films from the world-renowned Studio Ghibli, the Warner Bros. Discovery service is adding further strings to their anime bow by bringing twenty new movies to subscribers, with some making their North American streaming debut. The first batch of eight films is set to land on September 1, with the remaining twelve arriving through the remainder of 2025 and into 2026, making HBO Max one of the best streaming services for fans of Japanese animation.
