Demon Slayer: Infinity Castle I Hits Netflix September 28

Demon Slayer: Kimetsu no Yaiba Infinity Castle I is expanding to Netflix in the United States and additional regions on September 28, 2026. The film also began streaming on Crunchyroll on July 28, subject to regional licensing. The quickest way to answer “where can I watch it?” is to check the movie’s title page in your own country on each service; neither announcement promises a worldwide catalog.

When does Demon Slayer: Infinity Castle I come to Netflix?

Netflix Anime’s official teaser names September 28 for the expansion to more regions. Netflix’s U.S. announcement specifies the same date for the United States. The Netflix title page identifies the film, but what it displays can vary by location and account. In some territories it may say the movie is unavailable even though viewers elsewhere can watch it. That is a regional rights difference, not evidence that the September 28 rollout applies everywhere.

Netflix has not provided a complete public country-by-country list in the sources used here. Availability and the exact hour a title appears can depend on the territory. If the title page does not offer playback where you are, use your local Netflix catalog rather than a date quoted for another country.

Is Infinity Castle I already on Crunchyroll?

Yes, in licensed territories. Crunchyroll announced a July 28, 2026 streaming premiere and explicitly warned that availability could vary by region. Its current film page is the direct place to check whether the movie plays in your territory. Netflix’s September expansion is therefore not the movie’s first streaming release.

The two services are separate options where each holds rights. A Netflix listing does not, by itself, establish that Crunchyroll has removed the film; nor does the Crunchyroll announcement guarantee access in every country.

Which movie is this?

This is Infinity Castle I, the first film in the planned Infinity Castle story sequence, rather than a new season of the television anime. Its official synopsis begins with Muzan Kibutsuji attacking the Ubuyashiki Mansion as Tanjiro and the Hashira prepare for their final confrontation, sending them into the Infinity Castle. This guide avoids what happens after that setup.

If you are checking language options, use the film page for your own region. Netflix’s displayed audio and subtitles and Crunchyroll’s announced dub and subtitle list need not be identical in every market. Neither platform announcement here establishes a date for another Infinity Castle movie.

For readers new to anime generally, our beginner’s anime guide offers broader starting points. This film itself follows earlier Demon Slayer story arcs, so the title page is a streaming answer rather than a watch-order shortcut.
