Sony Is Reportedly Developing a Live-Action ‘Kaiju No. 8’ Adaptation with Unknown Details
Hollywood continues to show a strong interest in anime and manga adaptations, with studios eager to tap into franchises that come with established fan bases. Japanese properties are consistently at the forefront of this trend, and one of the latest hits may soon make its way to live action.
According to industry sources, Sony is reportedly working on a live-action adaptation of ‘Kaiju No. 8’. However, the report does not specify whether this will be a film or a series, nor does it mention any writers, directors, or producers involved. As of now, Sony has not confirmed these details, placing this news in the realm of speculation.
The development makes sense given Sony’s current position. The studio’s Crunchyroll division streams the anime, and Sony Pictures has previously managed theatrical releases for the franchise. A live-action adaptation would keep the property within the family as the anime nears its conclusion.

Created by Naoya Matsumoto, ‘Kaiju No. 8’ debuted on July 3, 2020, on Shueisha’s Shonen Jump+ platform. The story follows Kafka Hibino, a 32-year-old who cleans up monster remains for a living and gains the ability to transform into a kaiju. He subsequently joins Japan’s anti-kaiju Defense Force while concealing his secret and pursuing a promise made to a childhood friend.
The manga concluded with Chapter 129 on July 18, 2025, after a successful run of over five years, selling more than 18 million copies, with Viz Media publishing the English version. Matsumoto has mentioned that his own frustrations as a 30-year-old who hadn’t achieved his dreams inspired the story, along with influences from ‘Shin Godzilla’.
The anime adaptation, produced by Production I.G and featuring kaiju design supervision from Studio Khara, premiered in April 2024. Its first season aired throughout the summer, followed by a second season starting on July 19, 2025. A third season, dubbed the Final Chapter, was announced at Jump Festa and will adapt the manga’s conclusion, although a premiere date has yet to be revealed.
Sony has previously showcased the franchise on the big screen. In April 2025, Crunchyroll and Sony Pictures released ‘Kaiju No. 8: Mission Recon’, a compilation film that recaps the first season and includes a new episode titled ‘Hoshina’s Day Off’. This indicates that the studio sees theatrical potential in the property.
The timing aligns with Sony’s recent successes in the anime film market. Its ‘Demon Slayer: Infinity Castle’ opened to $70 million domestically in September 2025, marking the largest anime opening ever and becoming the highest-grossing anime film of all time. This success likely boosts executive confidence in adapting Japanese properties.
Live-action adaptations of anime are becoming increasingly common across various studios. For instance, Lionsgate’s live-action ‘Naruto’ movie is reportedly set to begin filming in early 2027. If the ‘Kaiju No. 8’ report holds true, Sony would be joining this expanding trend.
However, a live-action ‘Kaiju No. 8’ will face significant challenges. The narrative relies heavily on large creature designs and dynamic action sequences, necessitating extensive CGI. Subpar visual effects could jeopardize the entire project, and casting must balance fan expectations with broader appeal.
Additionally, the manga’s episodic format may require adaptation for a film or restructuring for a series. Fans have suggested potential directors, including Guillermo del Toro, known for his affinity for kaiju and anime, though this remains purely speculative.
Currently, there are no official details available. A formal announcement from Sony or Crunchyroll would clarify whether this project is a movie, a series, or something else entirely. Given that the report states the project is in development, it may be some time before production begins.
This uncertainty is typical for early-stage Hollywood projects, which can change rapidly or stall altogether. However, the rationale is compelling: a successful manga, a popular anime, and a studio that already controls the distribution pipeline. If anything, it’s surprising that it has taken this long to get to this point.
