Demon Slayer release timeline by format

Format guide:
- If you mean “When did the story begin?” use the manga debut (2016)
- If you mean “When did Demon Slayer first air?” use the anime premiere (April 2019).
- If you mean “When did the big movie releases start?” use Mugen Train (October 2020 in Japan).
Demon Slayer seasons and arcs release dates
Demon Slayer’s TV timeline is easiest to understand by arc, because streaming platforms may label seasons differently. The core release cadence is: Season 1 in 2019, a Season 2 era across late 2021 to early 2022, Season 3 in 2023, and Season 4 in 2024.
TV arc timeline (high-level but accurate):
- Season 1 (2019): the anime’s first full run begins April 6, 2019.
- Season 2 era (2021–2022): released in two parts for many viewers
- Mugen Train Arc (TV version) starts October 2021
- Entertainment District Arc runs December 2021 to February 2022

Demon Slayer movies: Mugen Train to Infinity Castle
Demon Slayer’s movie timeline begins with Mugen Train, which premiered in Japan on October 16, 2020, and later rolled out internationally.
The movie matters because it is not a side story; it continues the main plot and set a precedent for major story beats arriving in theaters.
The newest major theatrical milestone is Infinity Castle Part 1, which launched the finale as a planned trilogy. The first installment released in Japan on July 18, 2025, and in the U.S. and Canada on September 12, 2025.
This is why many current searches for “when do Demon Slayer come out” are actually asking about the newest Infinity Castle movie date rather than the franchise debut.
What is next after Infinity Castle Part 1?
The next confirmed continuation is Infinity Castle Part 2, but its broad public release dates are not consistently finalized across regions yet.
In practical terms, that means you should treat any specific year forecasts you see online as estimates until an official distributor announcement publishes a date for your market.
To stay updated without confusion, track two signals:
- Official distributor announcements in your country (these usually confirm month and day first)
- Local cinema listings once ticket sales begin (this confirms the date you can actually attend)
This approach keeps your timeline accurate even when theatrical rollouts differ between Japan, North America, and other territories.

The simplest watch order is to finish the TV arcs first, then move into the Infinity Castle movies. This keeps the story consistent even if your streaming service labels seasons in a different way.
