Movie or TV Version of Mugen Train?
Both tell the same story. The movie is the cinematic version that broke box-office records in Japan. The TV arc splits it into episodes and adds a new prologue episode. Pick whichever you can access — you don’t need both.
What Is “To the Hashira Training”?
A theatrical special released in early 2024 that combined the last episode of Swordsmith Village with the first episode of Hashira Training. Optional — the TV episodes cover the same content.
Infinity Castle Films
The final arc of the manga is adapted as a film trilogy. Part 1 released in 2025 and became a global box-office hit. Watch Season 4 first — Infinity Castle starts right where Hashira Training ends.
Where to Watch
The TV seasons stream on Crunchyroll, Netflix (many regions) and Hulu. The films come to cinemas first, then to streaming later.
