Mononoke the Movie: Chapter III – The Curse of the Serpent, the third and final film in the Mononoke Ooku trilogy, streams worldwide exclusively on Netflix starting September 29, 2026. Outside Japan, Netflix is the only announced viewing option, so an active subscription is required. Anime News Network reports the film opened theatrically in Japan on May 29, 2026, distributed by Twin Engine and co-produced by EOTA and Studio Kafka, in its December trailer coverage. The first two trilogy films are already streaming on Netflix, making a同一-night catch-up possible before the finale.

When and where can you stream it?
Netflix lists the film worldwide exclusively from September 29, 2026 as a Netflix Original anime film. Netflix Anime's trailer description identifies it by title ID 82012956, in the YouTube trailer listing.
For most readers, the practical path is simple. There is no separate theatrical or other streamer window announced outside Japan.
- Open Netflix and search the full title or ID 82012956.
- Confirm Phantom in the Rain and Ashes of Rage for catch-up.
- Keep an active subscription through September 29 for finale access.
Should you watch the first two films first?
Yes, if you want the Ooku storyline to land. Phantom in the Rain from 2024 and Ashes of Rage from 2025 precede this final chapter. Both are already streaming on Netflix.
Watch them in trilogy order rather than release-date guessing. That sequence establishes the inner-palace setting and the Medicine Seller's method. Then move directly to Chapter III on its streaming date.
What is Chapter III about?
The story returns to the Medicine Seller, voiced by Hiroshi Kamiya, inside Edo Castle's Ooku. He confronts the Serpent God, also called Hebigami. The focus is the Midaidokoro, the inner palace's highest-ranking woman.
That palace hierarchy drives the mystery and the haunting. New viewers should expect court intrigue tied to a supernatural force. Returning viewers get the trilogy's closing confrontation.
Who made it and what are the viewing limits?
Kenji Nakamura serves as chief director, with Tomoaki Koshida as director and Yasumi Atarashi as screenwriter. The film runs 87 minutes in Japanese and co-stars Haruka Tomatsu, Yoko Hikasa and Tomoyo Kurosawa. Animation Magazine notes the global limit in its September director interview coverage: outside Japan, access means Netflix, while the Ottawa International Animation Festival lists a September 23–27 screening just before streaming.
