Chainsaw Man's Reze Arc film hits Prime Video in Japan
A year after its Japanese cinema run, Chainsaw Man – The Movie: Reze Arc is streaming exclusively on Prime Video in Japan, with new key art to mark the launch.

Chainsaw Man – The Movie: Reze Arc is now streaming in Japan. The film went live on Prime Video at midnight on 19 September, a year after it opened in Japanese cinemas, and the franchise's site marked the launch with a new piece of key art.
The film that became the franchise's biggest bet
The film adapts the Reze arc of Tatsuki Fujimoto's Chainsaw Man, the stretch in which Denji, the teenager with a chainsaw devil's heart, meets a girl called Reze and finds his carefully unambitious life demolished by what follows. It was MAPPA's first theatrical outing with the franchise, and the official site records that it passed 6.55 million admissions and 10 billion yen in Japanese box office revenue.
Japan only, for now
The launch is a Prime Video Japan exclusive and needs an Amazon Prime membership, and the Japanese release notes that availability can change without notice. No international streaming date has been announced, so a subscription in the UK, Europe or the US will not get anyone the film today. That is the established pattern for this franchise: the theatrical run stayed domestic for months, and the television series reached different territories on different timetables.
Our opinion
A year is a long time to make a film's audience wait, and the fact that the home release of the Reze arc is a Japanese streaming exclusive says most of what you need to know about how anime distribution still works. The film was a genuine phenomenon, with 6.55 million tickets sold in a country whose cinema attendance everyone keeps fretting about, yet the version most of the world can actually reach remains undefined. The new key art is a small detail, but it is the right signal: this is a launch rather than a quiet addition to a library. Expect announcements territory by territory, because that is how this franchise has always done it, and it is precisely the kind of delay that sends impatient audiences looking for less legitimate options.
