Creative Vision and Production
Directed by Shingo Yamashita, “Cosmic Princess Kaguya!” marks his feature directorial debut. Yamashita is well-regarded for his work on opening sequences for popular anime series such as Jujutsu Kaisen Season 1 and Chainsaw Man. He co-wrote the screenplay with Saeri Natsuo.
The film is a joint production between Studio Colorido and Studio Chromato, the latter being Yamashita’s own studio, and Twin Engine also contributes to the production. Character designs are handled by Akihiro Nagae, who worked on Drifting Home, for the real-world aspects, and illustrator Hechima (known for My Oni Girl) for the virtual Tsukuyomi world designs.
The synopsis describes a story where Iroha Sakayori, a 17-year-old high school student in Tokyo, finds solace in the virtual realm of Tsukuyomi, administered by Yachiyo Runami. Her life takes an unexpected turn when she encounters a mysterious Kaguya, who emerges from a telephone pole. Their musical partnership unfolds within Tsukuyomi, but ominous forces seek to return Kaguya to the moon.
Beyond the film, a manga adaptation by Tarō Yoneda is slated to begin serialization in Kadokawa Shoten’s Comptiq magazine on January 9, 2026, with later chapters in Comic Comp. A novelization by Naruto Kiriyama, featuring illustrations by Asao Urata and additional scenes, is also set to be released by Kadokawa on January 30, 2026.
“Cosmic Princess Kaguya!” promises a unique fusion of traditional folklore, contemporary animation, and a rich musical soundscape, poised to captivate audiences worldwide when it launches on Netflix in January 2026.
