Human Vapor (Japanese: ガス人間, Hepburn: Gasu Ningen; Korean: 가스인간; RR: gaseuingan; lit.'Gas Man') is an upcoming Japanese-South Korean science fiction thriller television series based on the 1960 tokusatsu film The Human Vapor directed by Ishirō Honda. Written by Yeon Sang-ho and Ryu Yong-jae, and directed by Shinzo Katayama, the series stars Shun Oguri and Yu Aoi in their first live-action collaboration in 23 years.[1] It is a co-production between Toho Studios and South Korea's WOWPOINT, marking the first collaboration between Netflix and Toho. The eight-episode limited series[2] is scheduled for release on Netflix in 2026.[3]

Production

Development

The series originated from discussions between Toho producers and Yeon Sang-ho in 2018, during which Yeon selected The Human Vapor from Toho's "Transforming Human Series" for its blend of speculative science and human drama.[1] Yeon, known for global hits like Train to Busan (2016) and Netflix's Hellbound (2021), emphasized the original film's "skillful sci-fi expressions" and emotional core, stating: "While it is a sci-fi thriller, at its core, it is a story about people. We focused on treating human emotions with care and portraying the characters’ humanity."[1][4]

Script development took three years, with Ryu Yong-jae—Yeon's collaborator on Parasyte: The Grey (2024)—joining as co-writer.[5] Shinzo Katayama, acclaimed for Gannibal (2022), was selected as director for his ability to merge genre elements with intimate storytelling. Katayama, upon revisiting the original, noted: "I was intrigued by its blend of human drama and romantic elements, despite featuring an absurd creature like the Human Vapor."[1][6]

The project represents Netflix's first partnership with Toho, aiming to revive the studio's tokusatsu legacy for global audiences using cutting-edge VFX.[7] WOWPOINT, the production company behind Parasyte: The Grey, co-produces, infusing Korean expertise in genre storytelling.[8]

Casting

Casting announcements began in August 2024, with Shun Oguri and Yu Aoi confirmed as leads—reuniting after their last live-action project, the 2001 TV movie Ao to Shiro de Mizuiro (also known as 24 Eyes).[9] Yeon specifically envisioned Aoi for her role, citing her performances in Hana & Alice (2004) and Wife of a Spy (2020). Oguri, known internationally for Godzilla vs. Kong (2021), was selected for his star power and versatility.[6]

Filming and post-production

Principal photography commenced in September 2024 at Toho's Stage 9 in Tokyo, with additional location shoots in Shizuoka Prefecture from February to April 2025.[10] Filming wrapped in April 2025 after a brief pause in December 2024 due to Aoi getting a high fever, however, she returned to work after being discharged from the hospital.[3] The production incorporated practical effects alongside CGI to modernize the gaseous transformations, drawing from the original's tokusatsu roots.[11]

Open casting calls for extras ran through March 2025, offering non-commercial memorabilia as incentives.[12]

Release

Human Vapor is slated for a global Netflix premiere in April 2026.[3] Netflix co-CEO Ted Sarandos highlighted it as a flagship upcoming title during the company's 2025 earnings call, alongside anticipated returns like Bridgerton and One Piece.[13]
