TL;DR, Toei, Thai studio M Studio and South Korea’s Showbox are co-producing a live-action adaptation of Junji Ito’s The Long Hair in the Attic. Director Sitisiri Mongkolsiri is attached, with development finishing this year and filming scheduled for 2027.
The Long Hair in the Attic live-action film was announced by Toei, Thailand’s M Studio, and South Korea’s Showbox. Thai director Sitisiri Mongkolsiri is attached to helm. The companies say development will wrap this year, with filming scheduled for 2027.
The move brings Junji Ito The Long Hair in the Attic to a cross-border production model spanning Japan, Thailand, and Korea. Ito’s compact, brutal one-shots reward tight, director-led execution, which makes this partnership and director choice matter to horror fans. The story centers on Chiemi, a long-haired girl whose breakup curdles into body horror in an attic.
It previously reached screens in a 2000 Japanese film and a 2023 anime episode, so a new film will revisit the classic short.
Toei, Thailand’s M Studio, and South Korea’s Showbox jointly announced a feature adaptation of Junji Ito’s horror one-shot. Thai filmmaker Sitisiri Mongkolsiri will direct. The Long Hair in the Attic live-action film will finish development this year, according to the partners.
According to the announcement, filming 2027 is the target. No cast, locations, or distribution plan has been shared. The Toei M Studio Showbox collaboration sets a simple timeline, while keeping creative details under wraps until development closes.
Only core milestones are public, which keeps updates focused and verifiable. For comparison within recent page-to-screen moves, see the Tezuka live-action film. The teams did not disclose format specifics beyond this being a live-action film.
Director Sitisiri Mongkolsiri arrives with range across genre. His credits include The Red Line, Hunger, and Inhuman Kiss. The Sitisiri Mongkolsiri Junji Ito pairing points to careful atmosphere, measured rhythms, and attention to how fear creeps rather than crashes.
Translating Ito’s menace favors control, texture, and point of view over constant shocks. Mongkolsiri’s projects lean on sensory detail and mounting dread, traits that suit a Junji Ito live-action film. Expect clear blocking, lived-in spaces, and performances that carry the unease.
The producers have not outlined setting, language, or effects methodology, so specifics will follow development lock. What is clear is the director’s steadiness with intimate, character-led tension. That grounding can support hair-driven horror without smothering the human stakes.
Junji Ito published Yaneura no Nagai Kami in 1988 in Asahi Sonorama’s Monthly Halloween. The short follows Chiemi, dumped by her boyfriend after growing her hair to please him. When her sister fetches scissors to cut it, a scream leads to a decapitated body.
The Long Hair in the Attic manga has seen multiple screen versions. Japan produced a live-action film in 2000. The tale returned in 2023 as an episode of Junji Ito Maniac: Japanese Tales of the Macabre, keeping its unnerving premise in circulation.
English readers have encountered the story three times across publishers. The reprints track how a compact, cruel premise travels between markets and mediums without losing bite.
