Quick answer

Demon Slayer: Infinity Castle Part 2 is officially slated for 2027 , with no exact month or day confirmed yet. The final film (Part 3) is currently planned for 2029.

What we know so far

Official release window

  • Crunchyroll has confirmed the trilogy’s staggered schedule:
    • Part 1 already released theatrically in 2025 (Japan) and 2025–2026 internationally.
* **Part 2** : **2027**
* **Part 3** : **2029**
  • As of mid‑2026, there’s still no specific date (no month/day) for Part 2, only the year window.

Production status

  • In June 2026, Crunchyroll stated that Infinity Castle 2 is “actively in production” , but again without a firm release date.
  • Industry commentary notes that the first film took roughly 3–3.5 years to develop, which supports a multi‑year gap between entries and makes a 2027–2028 timeframe plausible.

Likely rollout pattern (based on Part 1)

If the studio follows a similar pattern to Part 1:

  • Japan premiere first , then
  • International/North America a couple of months later.

Given Part 1’s Japan release in mid‑2025 and North America in late 2025/early 2026, a common fan estimate is:

  • Japan : sometime in 2027 (often speculated around mid‑year)
  • North America/UK : late 2027 (e.g., September–October window), though this is purely speculative until officially announced.

Why the long wait?

  • The Infinity Castle arc is being adapted as a three‑film trilogy , not a TV season, which means longer production cycles per entry.
  • High‑quality animation, fight choreography, and source‑material fidelity all contribute to longer timelines between films.

Where to watch when it drops

Based on Part 1’s distribution:

  • Theatrical release first (Japan, then international).
  • Streaming later via Crunchyroll in most regions, following the theatrical window.

Bottom line

  • Confirmed: Infinity Castle Part 2 = 2027 ; Part 3 = 2029.
  • Not confirmed: Exact month/day, or whether it slips to 2028.
  • Status as of July 2026: Actively in production, no concrete date yet.
