When Cosmic Princess Kaguya! first hit theaters in Japan on February 20, 2026, nobody expected it to become the biggest original anime film event of the year. Now, as its theatrical run officially wraps up on June 18 with a staggering 2.526 billion yen at the Japanese box office, one thing is crystal clear.
This is the story of how a debut director, a classic folktale, and a virtual world tournament combined to create the first original Japanese anime film to cross the 1 billion yen threshold in 2026. And trust me, the numbers alone do not capture how wild this ride has been.
From Netflix Drop to Box Office Phenomenon
The film premiered on Netflix globally on January 22, 2026, with a limited theatrical release at Laemmle Glendale in California. Usually, when an anime film hits streaming first, theatrical performance suffers. Not this time.
The Japan theatrical release on February 20 sparked an unexpected surge. By March, it had already crossed the 1 billion yen milestone, becoming the first original Japanese anime film of 2026 to do so.
For comparison, even established franchises struggle to hit that mark. This was an original property — no manga source material, no built-in fanbase, no sequel advantage. Just a fresh story told by a passionate team.
The Creative Team Behind the Magic
At the center is director Shingo Yamashita, making his feature film debut. Yamashita co-wrote the screenplay with Saeri Natsuo, reimagining the ancient folktale The Tale of the Bamboo Cutter into a modern musical fantasy set in a virtual world called Tsukuyomi.
The film was produced by Studio Colorido alongside Studio Chromato and Twin Engine. The voice cast features Yūko Natsuyoshi, Anna Nagase, and Saori Hayami.

A Musical Soundtrack From Legends
The soundtrack was composed by Conisch, with songs from an all-star roster:
- Ryo of Supercell — the legendary producer behind early Vocaloid hits
- Yuigot — known for emotional, piano-driven compositions
- Aqu3ra — a rising star in the Vocaloid production scene
- HoneyWorks — one of the biggest names in Japanese anime music
- 40mP — a veteran Vocaloid producer with a massive following
- Kz of Livetune — the producer who helped bring Hatsune Miku to global audiences
This is a who is who of Japanese digital music production, and the fact that all of them contributed to a single film speaks to the creative magnetism of the project.
The Story: A Modern Folktale Meets Virtual Reality
The film follows Iroha Sakayori, a high school student who finds a baby inside a glowing utility pole. The baby rapidly grows into a girl from the Moon named Kaguya. Together they compete in a streamer tournament within the virtual world of Tsukuyomi, weaving themes of found family and identity.
At 142 minutes, the film takes its time building the world and relationships. The yuri elements add emotional depth that resonated far beyond typical anime movie demographics.
Why This Matters for Anime in 2026
In an era where anime films are increasingly tied to existing franchises, this proved that original stories still have massive commercial potential. The 2.526 billion yen total puts it among the top-grossing original anime films in recent years.
It is not just anime movies breaking records — My Hero Academia is teaming up with Japan national soccer team for the 2026 World Cup, and Solo Leveling Season 3 is confirmed for October. The anime industry is on fire in 2026.
What Happens Next
With the theatrical run ending on June 18, the film shifts focus to its Netflix streaming audience and potential home video release. The 2.526 billion yen total puts it among the top-grossing original anime films in recent years, and industry watchers are already speculating about whether Studio Colorido might consider a sequel or expanded universe.
