The official "Demon Slayer" account has confirmed that all current episodes of the anime are now available on Prime Video. This update covers the series content only and does not include the latest "Infinity Castle" film.
The available series include the TV version of the "Mugen Train" arc. This arc was initially released as a film and later adapted into a TV series with additional scenes. The "Hashira Training" arc is currently the final arc of the anime series, while the subsequent "Infinity Castle" arc is being adapted as a film trilogy.
The anime seasons and films of "Demon Slayer" are also available on Crunchyroll and Netflix, though release times may vary by region. Prime Video's addition of full series access does not mean that the film trilogy or all movies in the series are now available on the platform.
The "Infinity Castle" film trilogy was announced in 2024, with only the first installment released so far: it premiered in Japan in July 2025 and globally in September of the same year. There is no official release date for the second film yet, and the production team has not provided any new specific updates. A Super Stage event will be held at Jump Festa 2027 on December 19–20; whether new information about the films will be announced remains to be confirmed by the officials.
