by Netflix anime film “THE RIBBON HERO”, a new adaptation inspired by Osamu Tezuka’s classic manga Princess Knight, will receive a limited two-week theatrical release in Japan beginning September 4, 2026.

After its worldwide Netflix debut on August 8, THE RIBBON HERO is now heading to select Japanese theaters.
The film will be screened for two weeks from Friday, September 4, although the exact participating theaters should be checked through the movie’s official website and social media channels.
The decision to bring the Netflix anime to theaters comes after viewers praised its animation and character designs and expressed a desire to see the movie on a large screen. According to the production announcement, the theatrical release was decided in response to this interest.
This makes the theatrical run a special opportunity for fans who have already watched the movie on Netflix, as well as viewers who want to experience its action sequences, fantasy world, and detailed animation in a cinema.
First-Week Theatergoers Will Receive a “Reborn” CD
One of the biggest attractions of the limited theatrical release is the first-week attendance bonus.

The group’s official comments explain that they wanted the music to connect with the beautiful world and emotional themes of THE RIBBON HERO, while leaving an emotional impression even after the movie ends.
For fans who enjoyed the song while watching the film on Netflix, the theatrical bonus provides a chance to own a physical copy.
What Is “THE RIBBON HERO” About?
THE RIBBON HERO is a fantasy anime film inspired by Osamu Tezuka’s legendary manga Princess Knight.
The story centers on Princess Sapphire, a young woman whose homeland has been destroyed by a devastating calamity known as Nergal.
After losing everything in her kingdom of Silverland, Sapphire eventually arrives in Goldland.
There, she encounters new people and begins to discover hope again. However, her peaceful new life is threatened when Nergal appears once more.
Having already lost her homeland, Sapphire refuses to allow the same tragedy to happen again.
She takes up her sword and becomes the Ribbon Hero, choosing to fight against the darkness threatening her new home.
Netflix describes the film as the story of Sapphire’s fight to save her new home from the same fate that destroyed her homeland.
A Modern Interpretation of Osamu Tezuka’s “Princess Knight”
The original Princess Knight is one of Osamu Tezuka’s best-known works and an important title in the history of Japanese manga.
The original manga began serialization in Shōjo Club in 1953 and was later published in magazines including Nakayoshi and Shōjo Friend.
The story’s central character, Sapphire, is a princess who possesses both a boy’s heart and a girl’s heart. She becomes the Ribbon Knight and faces numerous challenges while protecting her kingdom.
The story was adapted into a television anime that aired from 1967 to 1968.
In 1999, an original short anime was screened at Tezuka Osamu World, which later closed in 2011. THE RIBBON HERO therefore marks the first new anime based on Princess Knight in 27 years.
Rather than simply recreating the original story, the new film uses Tezuka’s work as its foundation while presenting a modern fantasy adventure with a new setting, characters and visual style.
A Story About Loss, Courage and Starting Again
The title THE RIBBON HERO reflects one of the film’s major themes: rebuilding one’s life after experiencing loss.
Sapphire begins the story after losing her homeland and everything she once knew.
Instead of allowing that tragedy to define her future, she gradually finds new connections in Goldland.
However, when Nergal threatens her new home, Sapphire is forced to confront her past once again.
Her decision to fight is not simply about revenge.
She wants to protect the people she has come to care about and prevent others from experiencing the same kind of loss.
This gives the film a straightforward emotional foundation that is easy for newcomers to understand, even if they have never read Tezuka’s original Princess Knight.
Yuki Igarashi Makes His Feature-Film Directorial Debut
The film is directed by Yuki Igarashi, a highly regarded animator whose previous work includes the Star Wars: Visions episode “Lop and Ocho.”
Igarashi also attracted attention for his work on the first ending sequence of Jujutsu Kaisen Season 1. THE RIBBON HERO marks his first feature-length directorial project.
Animation production is handled by OUTLINE, the studio founded by Igarashi.
The production team also includes Kei Mochizuki as character concept designer, with Issei Arakaki handling animation character design. Cedric Herole serves as art director, while Okamaa is credited with the design of Nergal.
The combination of Igarashi’s animation background and the modern character designs gives the film a distinctive visual identity.
Saya Voices Princess Sapphire
The protagonist Sapphire is voiced by Saya, a member of the Japanese comedy duo Lalande.
This marks an important milestone for Saya, as THE RIBBON HERO is her first feature-length anime voice role.
Saya has spoken about her respect for anime and the challenge of taking on the lead role.
She also connected with Sapphire’s personality, particularly the character’s ability to respond to difficult circumstances with determination and humor.
The rest of the cast includes Seiran Kobayashi, Koki Uchiyama, Mayumi Shintani, Haruhiko Jo, Banjo Ginga, Aya Hisakawa, Yoshimasa Hosoya, Yusuke Tezuka and Mito Tsukino, among others.
New Characters Add More Mystery to Sapphire’s Journey
The film introduces several characters who are not simply copies of the cast from the original manga.
Among them are Pine, voiced by Seiran Kobayashi; Velvet, voiced by Koki Uchiyama; and Zircon, voiced by Mayumi Shintani.
Velvet in particular is presented as an intriguing figure whose motives are not immediately clear.
Netflix’s promotional material has also highlighted the relationship between Sapphire and the people she meets after leaving her destroyed homeland.
These new elements allow longtime Princess Knight fans to approach the movie as a fresh interpretation rather than simply a remake.
The Film Has Already Attracted International Attention
Although THE RIBBON HERO is receiving a limited theatrical release in Japan, the movie is already available worldwide through Netflix.
Netflix’s official site lists the film as a 2026 Japanese anime movie and describes it as a fantasy and action-adventure title based on manga.
The production announcement also noted that the film reached No. 4 on Netflix’s domestic “Today’s Top 10 Movies” ranking the day after its streaming debut. It has also received attention from viewers overseas, including in Taiwan and South Korea.
This international response is particularly interesting given that Princess Knight itself is a landmark work from the early history of Japanese shōjo manga.
Why the Theatrical Release Is Special for Netflix Viewers
For many viewers, Netflix anime films are primarily experienced at home.
A limited cinema release changes that experience.
The large screen can make the film’s action sequences, background art, and character animation more impressive, particularly for a production built around fantasy battles and dramatic visual moments.
It also allows existing fans to watch the movie with other viewers and potentially collect exclusive theatrical merchandise.
The limited two-week schedule, however, means that fans interested in seeing THE RIBBON HERO in theaters should check the participating venues and screening times in advance.
What Makes This Release Worth Watching?
There are several reasons THE RIBBON HERO is attracting attention.
First, it brings a legendary Osamu Tezuka property back to anime in a completely new form.
Second, it is the first new Princess Knight anime in 27 years.
Third, the film represents the feature directorial debut of Yuki Igarashi, whose previous animation work has already attracted considerable attention.
Finally, the combination of modern animation, a classic heroine, an original fantasy setting, and a new music project gives the film an identity of its own.
The limited theatrical release also adds an extra incentive for collectors, particularly during the first week when the exclusive “Reborn” CD will be distributed.
Final Thoughts
“THE RIBBON HERO” is entering an interesting new stage following its worldwide Netflix debut.
Starting September 4, 2026, the film will receive a two-week limited theatrical release in Japan, giving fans a chance to experience the modern Princess Knight adaptation on the big screen.

With an exclusive jacket illustration drawn by character concept designer Kei Mochizuki. The bonus will be distributed from September 4 through September 10 while supplies last.
For longtime fans of Osamu Tezuka, the film represents the return of Princess Knight to anime after 27 years. For newcomers, it offers a self-contained fantasy adventure about a young heroine who loses her homeland, finds a new home and decides to stand up against the threat that follows her.
