Natsuki Hanae's Four Tips for Watching at Home
Natsuki Hanae (Tanjiro Kamado in Demon Slayer, Ken Kaneki in Tokyo Ghoul) voices Beam, the shark fiend who spends a good chunk of Reze Arc serving as Chainsaw Man's ride. On September 20, Prime Video's official YouTube channel posted a "home edition" viewing guide with Hanae as host. The label is a callback: a cheer-screening etiquette video for the film ran during its theatrical release, and this one adapts the idea for the living room.
According to Japanese anime news site Anime Anime, the video walks through four ways to get the most out of the film at home. Among them: shout at the screen without worrying about the people around you, rewind and replay your favorite scenes, and decorate your room to set the mood. The pitch is that streaming allows things a theater never could.
A Rental Shop Shelf Built Around "The Ultimate Shark Movie"
The bigger stunt starts September 21. Through September 27, the Metro Promenade at Shinjuku Station hosts a large display-style outdoor ad designed to look like a rental video store. The concept comes from the film's theatrical run, when shark-movie fans started calling Reze Arc "the ultimate shark movie." Prime Video ran with the joke and paired the film with 30 hand-picked shark movies.
Here is what goes on the shelf. Prime Video produced a special poster that restyles Reze Arc as an old-fashioned shark flick. There's a 3D panel of Chainsaw Man riding Beam, recreating the scene from the film. Then the main event: VHS cases for Reze Arc and all 30 shark movies, lined up the way a rental shop would stock them. The Reze Arc VHS comes in two case designs, and this display is billed as the only place to see them.
A corner of picks "recommended by Tatsuki Fujimoto," the manga's creator, rounds it out, complete with video-store-style shelf-talker cards. The rest of the space is covered in film stills, life-size character illustrations, the five key visuals used during the theatrical release, and a new visual drawn specifically for the Prime Video launch.
The Film Behind the Campaign
Reze Arc adapts the arc of Fujimoto's manga in which Denji, now a Public Safety Devil Hunter in Special Division 4, is giddy over a date with Makima when a sudden downpour hits. While sheltering from the rain, he meets a girl named Reze. She works at a nearby cafe, smiles at him, and the two get close fast. From that meeting on, Denji's daily life starts to change.
MAPPA (Jujutsu Kaisen, Attack on Titan Final Season) produced the film, with Tatsuya Yoshihara directing, Hiroshi Seko on the screenplay, Kensuke Ushio on music, and Kazutaka Sugiyama on character design. Kikunosuke Toya voices Denji, Reina Ueda plays Reze, and Tomori Kusunoki returns as Makima, alongside the TV series cast including Shogo Sakata as Aki Hayakawa and Fairouz Ai as Power. Kenshi Yonezu's "IRIS OUT" is the theme song, and Yonezu and Hikaru Utada share the ending theme "JANE DOE."
The film opened in Japan on September 19, 2025, distributed by Toho, and went on to pass ¥29.7 billion (roughly $200 million) at the worldwide box office. The TV anime that preceded it began airing in October 2022.
Looking Ahead
The Shinjuku Station display is a one-week affair, September 21 through 27, 2026. Anyone in Tokyo that week can walk the Metro Promenade and see the VHS shelf for free.
In Japan, the film is a Prime Video subscription exclusive as of September 19, 2026. International fans have had an easier time: a Final Weapon report from August notes the film was already streaming on Crunchyroll outside Japan with English subtitles and an English dub before the Japanese streaming launch. The Prime Video Japan announcement doesn't change that arrangement.
The source manga runs under Shueisha's Jump Comics label, and Viz Media publishes it in English. There's no word yet on whether the two exclusive VHS case designs will ever be sold, so for now the Shinjuku shelf is the only place they exist.
