When does Demon Slayer: Infinity Castle Part 3 release? It is the trilogy's final ufotable film — no official theatrical day yet; circulating 2029 windows remain unverified.
Infinity Castle Part 3 is the announced trilogy closer after Parts 1 and 2. ufotable/Aniplex have not stamped an opening Friday; treat rumor years as speculation until Toho prints a real date.
When Is Demon Slayer Infinity Castle Part 3?
No official premiere day is confirmed. Bookmark this page — we add a countdown as soon as a date is announced.
Part 3 is the announced trilogy finale — still without a stamped opening day
Infinity Castle was sold as three movies. Part 3 is the closer that has to land Muzan’s last war after Parts 1 and 2. ufotable has not published that Friday. This page tracks the finale slot honestly: confirmed as film three, undated as a calendar event.
Do not merge Part 3’s countdown with Part 2’s rumor year
Search results mash “2027 Part 2 / 2029 Part 3” into one sentence. Even if those gaps were ever true, they would be different premieres. Part 3 is only the ending film; Part 2 is the bridge. Mixing them invents one fake date for two tickets.
Trilogy order on the record
- Part 1 — Japan theatrical July 18, 2025 (opened; cliffhanger start of the final battle).
- Part 2 — middle film; premiere day not announced.
- Part 3 — trilogy finale; premiere day not announced (this page).
- Rumor years (e.g. 2027 / 2029) — speculative; not Aniplex locks.
Part 3 has to carry the manga’s last pages — that is why the date stays the slowest stamp
Finale films freeze marketing until the middle chapter’s spoiler wall drops. Demon Slayer’s ending is already printed in the manga; the movie still needs ufotable’s schedule and Toho’s calendar. A blank Part 3 countdown is patience, not a missing leak.
Frequently asked questions
Quick answers about this release date.
1When does Demon Slayer: Infinity Castle Part 3 release?
No official theatrical day yet. Part 3 is announced as the trilogy’s final film, but Aniplex/ufotable have not stamped a premiere. Years like 2029 that circulate online remain unverified windows.
2Is Part 3 the end of the Demon Slayer anime?
It is framed as the Infinity Castle trilogy closer — the theatrical wrap of the manga’s final battle arc that Part 1 began. That is the ending path for this adaptation plan, separate from older TV cours.
3Why does this site sometimes show January 1, 2029?
That was a working year placeholder from rumor maps, not a Toho lock. Prefer “Not announced” until a real Friday appears — do not book travel on the placeholder.
4Should I watch Part 2 before worrying about Part 3?
Yes. Part 3 is the finale after Part 2’s middle chapter. Part 1 (July 18, 2025 Japan) is already out; Part 2’s date is also unset. Finale hype without the middle film is getting ahead of the trilogy order.
