The anime film Mononoke the Movie: Chapter 3, The Serpent God, which opened in Japanese theaters in May 2026, will be exclusively streamed worldwide on Netflix starting Tuesday, September 29. This installment is the concluding chapter of a new theatrical trilogy based on the 2007 TV anime Mononoke, which itself originated from the Bakeneko arc of Ayakashi: Samurai Horror Tales. The trilogy is set in the Ooku, the inner chambers of the shogun's palace, and follows the Medicine Seller, voiced by Hiroshi Kamiya, as he exorcises vengeful spirits. Each chapter shifts perspective to a woman of higher status: a new maid in Chapter 1, The Phantom Rain; an elite senior maid in Chapter 2, The Fire Rat; and the Midaidokoro, the highest-ranking woman, in Chapter 3. The third film centers on Sachiko, voiced by Atsumi Tanezaki, whose newborn son dies, triggering a conspiracy tied to the Ooku's founding 150 years earlier. The theme song is No Epilogue by Aina The End. Chapters 1 and 2 are already streaming on Netflix, so the full trilogy will be available at once.
- Miyuki Sawashiro voices the Third Midaidokoro, a character whose connection to Tenkyoku and the Mizorogi family secret is revealed in Chapter 3.
- Kenjiro Tsuda plays Mizorogi Hokuto, the priest of the Ooku's faith "Omizusama," who watches the events with a solemn expression.
- The Emperor is voiced by Miyu Irino, and the cast also includes Yoshiko Sakakibara, Tomoyo Kurosawa, Rie Takahashi, Haruka Tomatsu, Yuuki Kaji, Jun Fukuyama, and Yukana as Tenkyoku.
- Kenji Nakamura serves as general director, with Tomoaki Koshida directing. The screenplay is by Shinhakkaku, and the music is by Taku Iwasaki.
- Animation production is by Studio Kafka EOTA, with production and distribution by Twin Engine.
- The box office revenue for the first three days of release surpassed the pace of Chapters 1 and 2, a strong start for the series finale.
- Fan reactions quoted in the announcement include "a sense of speed like riding an attraction" and "so dense you wouldn't think it's under 90 minutes."
- A new Mononoke project was announced in July 2026, introducing a third Medicine Seller named Ken, following the TV series' Ri and the theatrical films' Kon.
- Three completely new novels, each starring one of the three Medicine Sellers, will be published by Kadokawa Bunko.
