Osamu Tezuka's properties are in active adaptation across film, television, and documentary, with The Ribbon Hero streaming on Netflix since August 8, 2026, an Astro Boy reboot set for 2027, and a live-action NHK special premiering in August.
Osamu Tezuka's work is being adapted across multiple formats in 2026, with each project drawing on a different facet of his legacy. The most recent is The Ribbon Hero, an animated film based on his 1953 manga Ribbon no Kishi, which began streaming on Netflix on August 8. Director Yuki Igarashi said he aimed to recreate the impact the original manga had in its time, updating its pioneering female hero concept for a global audience. The film is Igarashi's feature-length directorial debut, produced at his new studio OUTLINE with production by Twin Engine. Character designs come from Kei Mochizuki, with Mai Yoneyama as collaborator.
The film marks the first anime project in the Princess Knight franchise in 27 years. Its final trailer, released July 30, added five cast members and previewed the English dub. The cast includes Saya from comedy duo Lalande as Sapphire, in what Netflix says is her first leading role in a feature-length animated production. Three of the new cast members, Mito Tsukino, Lunlun, and Debidebi Debiru, are NIJISANJI VTubers taking their first roles in a feature-length anime.
Tezuka's other properties are also in motion. Astro Boy Reboot, a French-produced series presented at the 2026 Annecy Animation Film Festival, gives the robot hero a secret identity, a narrative addition that required Tezuka Productions' approval. The series is set for a 2027 release. NHK is producing a live-action special based on Tezuka's autobiographical manga Paper Fortress, titled Tezuka Osamu no Sensō, starring Kengo Kōra as Tezuka. It premieres in August. A documentary, TEZUKA! God of Manga, includes a clip where director Jorge Gutierrez recalls discovering Astro Boy on Mexican TV in the 1980s, arguing the serialized storytelling felt familiar to audiences raised on telenovelas.
