Kazuo Umezz is the subject of two ongoing projects: a limited-time immersive horror event based on The Drifting Classroom, and the first English-language release of his Ultraman manga, scheduled for July 2027.
Kazuo Umezz, best known for horror manga such as The Drifting Classroom and Reptilia, is currently in the spotlight through two distinct projects. The first is an immersive event based on The Drifting Classroom, run by NO MORE Inc. and Coamix Inc. The event, titled 'UMEZZ HORROR HOUSE ~Drifting Classroom and Thought Experiment Exhibition~ Scariest ver.', opens August 19 at GALLERY ZENON in Kichijoji. It adds new cast horror performances and enhanced spatial staging to deepen the immersion of entering the manga's world. Tickets went on sale August 14 at 20:00.
The second project is a licensing announcement from Seven Seas Entertainment. On July 17, 2026, the publisher acquired the rights to Umezz's Ultraman manga, which originally ran in Japan from 1966 to 1967 alongside the debut of the Ultraman tokusatsu television series. The release, titled Ultraman by Kazuo Umezz: The Classic Manga Collection, will be a large-trim hardcover priced at $42.99 in the United States and $57.99 in Canada, arriving in July 2027. This is the first English-language edition of the manga.
Seven Seas described the release as timed to the franchise's 60th anniversary. A documentary film, The Origin of Ultraman, produced by Tsuburaya Productions, opened in Japanese theaters on July 3, 2026, also celebrating the anniversary. Together, these stories show Umezz's work being presented in new formats, from an interactive horror exhibition to a premium collected edition of his tokusatsu adaptation.
