The official website for Chainsaw Man – The Movie: Reze Arc has released a new promotional video, offering a sneak peek at the film’s ending theme song, “JANE DOE”. The track is a collaboration between popular artists Kenshi Yonezu and Hikaru Utada, generating considerable excitement among fans. The film opened in Japanese theaters today, September 19, 2025.
A Star-Studded Collaboration for the Reze Arc
The choice of Kenshi Yonezu and Hikaru Utada for the ending theme brings together two of Japan’s most prominent musical talents. Kenshi Yonezu previously contributed the opening theme “KICK BACK” to the Chainsaw Man TV anime, which achieved global success, becoming the first Japanese-language song to be RIAA Gold-certified in the U.S.. Yonezu is also performing “IRIS OUT,” the official theme song for Chainsaw Man – The Movie: Reze Arc.
The collaboration for “JANE DOE” was initiated by Yonezu, who felt Utada’s melancholic yet sweeping voice was uniquely suited for the song as it began to take shape. Utada expressed their enthusiasm for the project, acknowledging the challenge and excitement of merging their distinct styles with Yonezu’s. The collaboration has been highly anticipated since its initial announcement in August, with a teaser video for “JANE DOE” released at that time. The full digital single for “JANE DOE” is set to be released on September 22.
The “Reze Arc” on the Big Screen
Chainsaw Man – The Movie: Reze Arc adapts a highly popular storyline from Tatsuki Fujimoto’s Chainsaw Man manga, focusing on Denji’s encounter with the mysterious girl Reze. Reina Ueda voices Reze in the film. MAPPA, the studio behind the acclaimed TV anime, is producing the movie, with Tatsuya Yoshihara directing and Hiroshi Seko returning as screenwriter.
The film’s plot follows Denji, now “Chainsaw Man” and a member of Special Division 4’s devil hunters. His life takes an unexpected turn after meeting Reze, a girl working in a café, leading him into an unpredictable destiny.
Global Release and Special Screenings
While the film premieres in Japan today, it will also receive a wide international release. Sony Pictures Entertainment (SPE) has acquired worldwide theatrical rights, with the film opening in the United States on October 24, and in the United Kingdom and over 80 other countries on September 24. Japanese screenings will include midnight showings in major cities and special MX4D, 4DX, and Dolby Cinema formats.
