by 2026 is turning into a remarkably strong year for animated films in Japan. From the unexpected blockbuster success of Chiikawa: The Secret of Mermaid Island to the continued strength of the Detective Conan franchise and the return of Puella Magi Madoka Magica, anime and animated movies are attracting audiences across a wide range of genres.
The biggest recent headline comes from Chiikawa: The Secret of Mermaid Island, the first feature film based on Nagano’s popular Chiikawa franchise. Released in Japan on July 24, 2026, the movie has earned more than ¥15.84 billion at the domestic box office after 59 days, with approximately 10.857 million admissions. It is currently the highest-grossing film released in Japan in 2026.
The success is particularly notable because Chiikawa is very different from traditional blockbuster anime franchises. Its characters are small, cute, and seemingly simple, but the stories often combine comedy, emotional drama, and unexpectedly harsh situations.
At the same time, other animated films have demonstrated that major box-office success in Japan is no longer limited to one particular type of anime. Detective Conan: Fallen Angel on the Highway crossed the ¥10 billion mark, while Disney and Pixar’s Toy Story 5 also became a major theatrical hit. Meanwhile, Puella Magi Madoka Magica the Movie -Walpurgisnacht Rising- opened at No. 1 during its first weekend, showing strong demand for a franchise that had not received a new theatrical installment for approximately 13 years.
Chiikawa Becomes the Biggest Japanese Movie of 2026 So Far
The biggest development is undoubtedly Chiikawa: The Secret of Mermaid Island.
The movie opened in Japan on July 24, 2026, and has continued to perform strongly throughout its theatrical run. As of September 20, the film had attracted 10,857,000 viewers and generated ¥15.84 billion in box-office revenue over 59 days. That result puts it at the top of the domestic 2026 box-office chart.
The film adapts the popular Siren Arc from Nagano’s original Chiikawa manga. Rather than simply adapting short television episodes, the movie expands the story into a feature-length adventure specifically created for the big screen.
The story follows Chiikawa, Hachiware, and Usagi, who are invited to an island where they become involved with a mysterious mermaid-related incident.
The island initially appears to be an exciting destination, but the characters soon discover that its inhabitants are hiding a secret.
That combination of cute character designs and a surprisingly serious storyline has become one of the defining characteristics of Chiikawa.
Why Chiikawa’s Success Is So Interesting
For newcomers, Chiikawa may not initially look like the kind of franchise that would produce a ¥15 billion theatrical hit.
The characters are tiny and adorable, and many of the original stories are extremely short.
However, the franchise has gradually built an enormous audience.
The manga began as illustrations posted by Nagano on social media, eventually developing into a major multimedia franchise. The series follows Chiikawa and friends such as Hachiware and Usagi as they experience everyday adventures, work, eat, make friends, and occasionally find themselves in surprisingly dangerous situations.
The contrast between the cute visual style and the harsher elements of the world has become one of the franchise’s biggest attractions.
The anime adaptation also expanded the series’ audience. The television anime began airing in 2022, and its official YouTube catch-up videos have accumulated more than 500 million views, according to Fuji TV.
The franchise has also received the Japan Character Award Grand Prix multiple times, further demonstrating its popularity beyond anime viewers alone.
Chiikawa’s Movie Success Comes From a Different Formula
One of the interesting aspects of the 2026 Japanese box office is that the biggest animated movies are not all successful for the same reason.
Detective Conan has decades of franchise history behind it.
Toy Story has a worldwide audience and three decades of character recognition.
Chiikawa, meanwhile, grew from a social-media manga and character brand.
That makes the film’s current box-office performance particularly notable.
The movie has also continued to receive additional theatrical events and special screenings, helping maintain interest after its initial release.
Its strong performance demonstrates how a character franchise that originally grew through short-form online content can eventually become a major theatrical property.
Detective Conan Continues Its 100-Billion-Yen Era
Another major anime success story in 2026 is Detective Conan: Fallen Angel on the Highway.
The 29th Detective Conan theatrical film opened in Japan on April 10, 2026.
Within just 27 days, it had attracted more than 7.4 million viewers and earned approximately ¥10.88 billion.
The achievement was significant because it extended an extraordinary run for the franchise.
Fallen Angel on the Highway became the fourth consecutive Detective Conan movie to surpass ¥10 billion in Japanese box-office revenue.
The previous three were:
- Detective Conan: Black Iron Submarine — 2023
- Detective Conan: The Million-dollar Pentagram — 2024
- Detective Conan: One-eyed Flashback — 2025
- Detective Conan: Fallen Angel on the Highway — 2026
The 2026 film therefore continued a four-year streak that had already established Detective Conan as one of Japan’s most reliable theatrical anime franchises.
The film follows Conan and other characters as they become involved in a dangerous mystery surrounding a black motorcycle and a motorcycle festival in Yokohama.
The story also gives significant attention to characters connected to the Kanagawa Prefectural Police, adding another layer to the long-running mystery franchise.
Toy Story 5 Shows That the Boom Is Not Limited to Japanese Anime
The animated-film boom in Japan is not restricted to Japanese anime.
Disney and Pixar’s Toy Story 5 has also become one of the country’s biggest animated releases of 2026.
The film opened in Japan on July 3, 2026, and crossed the ¥10 billion mark after only 34 days. By August 12, its cumulative Japanese box office had reached approximately ¥11.07 billion, with more than 7.92 million admissions.
It subsequently surpassed ¥12 billion in Japan, according to Disney’s August 27 update, making it the highest-grossing Toy Story film in the Japanese market and the highest-grossing Pixar film there at the time.
The worldwide performance has also been enormous. Disney reported that the film had passed $1 billion worldwide, making it one of the major global animated hits of 2026.
This is an important part of the broader 2026 story: audiences are turning out for both Japanese anime franchises and internationally produced animated films.
Madoka Magica Returns After More Than a Decade
Another major talking point is Puella Magi Madoka Magica the Movie -Walpurgisnacht Rising-.
The movie opened in Japan on August 28, 2026, marking the first new theatrical Madoka Magica film in approximately 13 years following Puella Magi Madoka Magica the Movie Part III: Rebellion in 2013.
The return generated significant interest from longtime fans.
During its first three days, Walpurgisnacht: Rising attracted approximately 530,000 viewers and earned more than ¥930 million, debuting at No. 1 in the Japanese weekend box office.
The film is a direct continuation of the story associated with the original Madoka Magica universe, making it particularly significant for longtime fans who have been waiting years for a new theatrical chapter.
Its opening performance also demonstrates that established anime franchises with a strong core audience can still generate substantial theatrical interest even after a long gap between releases.
Madoka Magica’s Success Is Different From Chiikawa’s
The contrast between Chiikawa and Madoka Magica is particularly interesting.
Chiikawa appeals to a broad audience through cute characters, merchandise, television anime, social-media popularity, and accessible storytelling.
Madoka Magica, meanwhile, is a darker fantasy series with a much more complex narrative and a strong long-term fanbase.
The two franchises therefore represent different paths to theatrical success.
One grew from social media and character culture.
The other built its audience through television anime, films, merchandise, games, and years of dedicated fandom.
Yet both have demonstrated that anime movies can attract substantial audiences in Japan.
Mobile Suit Gundam Hathaway Expands the Anime Movie Market
Another notable 2026 release is MOBILE SUIT GUNDAM HATHAWAY The Sorcery of Nymph Circe, which opened in Japan on January 30, 2026.
The film is the second installment in the planned Mobile Suit Gundam Hathaway trilogy and continues the story of Hathaway Noa.
The movie is directed by Shukou Murase, with Kensho Ono voicing Hathaway Noa.
It also performed strongly enough to surpass ¥2 billion in Japanese box-office revenue, with more than 1.2 million admissions reported in February.
For international fans, the film was also released in North American theaters in May 2026 and later arrived on Netflix.
The film’s performance is notable because Gundam Hathaway is aimed at a more established science-fiction and mecha audience than broad family-oriented animated films.
Its success adds another example of the increasingly varied audience for Japanese theatrical animation.
What Is Gundam Hathaway: The Sorcery of Nymph Circe?
For newcomers, MOBILE SUIT GUNDAM HATHAWAY The Sorcery of Nymph Circe belongs to the Universal Century timeline of the Gundam franchise.
The story follows Hathaway Noa, the son of the legendary Federation officer Bright Noa.
Hathaway has become the leader of the anti-Federation organization Mafty, which is conducting a campaign against high-ranking government officials.
The film combines political science fiction, giant robot battles, espionage, and character drama.
Its more serious tone and connection to earlier Universal Century stories make it a different type of theatrical experience from Chiikawa or Detective Conan.
The Super Mario Galaxy Movie Also Becomes a Major Hit
Another important animated success story is The Super Mario Galaxy Movie.
Released in Japan on April 24, 2026, the film quickly became one of the year’s major theatrical attractions.
By June 14, Japanese box-office revenue had exceeded ¥7.5 billion, with more than 5 million admissions.
Its worldwide performance was even larger.
The movie passed $1 billion in worldwide box-office revenue during its theatrical run. By June 14, the worldwide total had exceeded $1.002 billion, according to the film’s official Japanese website citing Box Office Mojo data.
The success follows the enormous international popularity of the earlier Super Mario Bros. Movie and demonstrates the power of video-game adaptations in the animation market.
Milky☆Subway Shows That Smaller Anime Projects Can Also Reach Theaters
One of the more unusual films mentioned in connection with 2026’s anime movie landscape is Galaxy Express Milky☆Subway: Local Train to the Theater.
Its official Japanese title is Ginga Tokkyu Milky☆Subway Ekieki Teisha Gekijo-yuki, and it opened on February 6, 2026.
The film is a theatrical re-edit of the 12-episode short anime Milky☆Subway, with new scenes added for the theatrical version.
The story follows characters including Chiharu and Makina, who are ordered to clean the interplanetary train known as the Milky☆Subway as community service after being arrested for violating galactic traffic laws.
Naturally, the simple cleaning assignment does not go according to plan.
The train suddenly goes out of control, and the characters become involved in a much larger incident.
The film is a useful example of how the anime industry is experimenting with different production scales. A short-form web and television project can gain enough popularity to receive a theatrical release.
Why Milky☆Subway Stands Out
Milky☆Subway began as a short-form project with an unusual science-fiction setting and a deliberately quirky tone.
The anime developed a following through its distinctive dialogue, character interactions, and visual style.
According to Shin-Ei Animation, the original 12-episode series generated significant attention both in Japan and internationally, with its official YouTube channel surpassing 150 million total views before the theatrical film was announced.
The theatrical version therefore represents a different path to the big screen compared with major franchise films such as Detective Conan or Gundam.
The Variety of 2026 Anime Movies Is the Real Story
Looking at these films together reveals something important about the 2026 Japanese film market.
The successful animated releases are not all following the same formula.
There are:
Long-running anime franchises:
Detective Conan
Character-driven social-media franchises:
Chiikawa
Long-running science-fiction properties:
Mobile Suit Gundam Hathaway
Dark fantasy anime:
Puella Magi Madoka Magica
International family animation:
Toy Story 5
Video-game adaptations:
The Super Mario Galaxy Movie
Independent or short-form anime projects:
Milky☆Subway
This variety is arguably one of the most interesting aspects of the current theatrical animation market.
Three 2026 Releases Have Already Crossed ¥10 Billion
As of September 21, three films released in Japan during 2026 have crossed the ¥10 billion domestic box-office milestone:
- Detective Conan: Fallen Angel on the Highway
- Toy Story 5
- Chiikawa: The Secret of Mermaid Island
Detective Conan crossed ¥10 billion in May, Toy Story 5 passed the milestone in August, and Chiikawa followed with an even larger total by September.
Meanwhile, Zootopia 2, which originally opened in December 2025, also crossed the ¥10 billion mark during its run in Japan and therefore contributes to the broader 2026 box-office picture, but it should not be described as a 2026 release.
That distinction is important when discussing the year’s theatrical results.
Anime Is No Longer One Single Box-Office Category
The results of 2026 also show why it is increasingly difficult to describe “anime audiences” as one group.
A family might go to see Toy Story 5.
A longtime anime fan might choose Madoka Magica.
A Gundam fan might see Hathaway.
A child may discover Chiikawa through its television anime and then see the movie with their family.
A longtime Detective Conan viewer may return to theaters because the annual movie has become part of their routine.
These films can all succeed for completely different reasons.
Why Theatrical Anime Continues to Grow
One reason for the continued strength of anime movies is the connection between theatrical releases and other forms of media.
A successful anime can have:
- Television episodes
- Manga
- Light novels
- Video games
- Character merchandise
- Music
- Social-media communities
- Streaming releases
- Special theatrical screenings
A movie can therefore become an event that brings together several parts of a franchise.
Chiikawa is a particularly clear example. Its manga, television anime, character merchandise, social-media presence, and theatrical film all reinforce one another.
Gundam has an even longer multimedia history, combining anime, games, Gunpla, music, merchandise, and live events.
The Importance of Word of Mouth
Another factor behind many of these films is word of mouth.
Audiences can discover a movie through social media, clips, fan discussions, trailers, merchandise, or television coverage.
This can be particularly important for films that do not initially appear to be conventional mainstream blockbusters.
Chiikawa is an excellent example of this phenomenon.
The franchise’s characters are already widely recognizable, but the movie’s combination of humor, adventure, emotional storytelling, and the popular Siren Arc has encouraged audiences to experience the story on the big screen.
What Makes Chiikawa’s ¥15.84 Billion Result Significant?
The ¥15.84 billion result is important not simply because of the number itself.
It places a character franchise that began with short social-media illustrations at the top of Japan’s 2026 domestic box office.
As of September 21, Chiikawa: The Secret of Mermaid Island has overtaken every other 2026 Japanese release in total domestic gross.
It also means the movie has moved beyond being merely a successful adaptation.
It has become one of the year’s defining theatrical releases.
The film’s current total is also above the ¥15.8 billion domestic gross previously recorded by Detective Conan: The Million-dollar Pentagram in 2024, placing Chiikawa among the strongest-performing Japanese animated films in recent years.
What Comes Next for Anime Movies?
The strong performance of animated films in 2026 could have an impact beyond the current year’s box-office rankings.
Studios and publishers have increasingly demonstrated that theatrical animation can support projects with very different target audiences.
The success of a character-focused movie such as Chiikawa alongside major franchise films such as Detective Conan, Gundam, and Madoka Magica suggests that theatrical anime is becoming increasingly diverse in terms of genre, audience, and production style.
The remaining months of 2026 will also determine how the final annual rankings develop, with several major films still scheduled or continuing their theatrical runs.
2026 has become a standout year for animated films in Japan, not because one particular genre or franchise dominates the market, but because so many different kinds of animated productions are finding audiences.
Chiikawa: The Secret of Mermaid Island is the clearest example of the year’s unexpected theatrical strength. After 59 days, it has reached ¥15.84 billion and 10.857 million admissions, making it the highest-grossing film released in Japan in 2026 so far.
Detective Conan: Fallen Angel on the Highway continued the franchise’s extraordinary run by becoming its fourth consecutive ¥10 billion film, while Toy Story 5 crossed ¥10 billion in Japan and later surpassed ¥12 billion.
At the same time, Puella Magi Madoka Magica the Movie -Walpurgisnacht Rising- demonstrated the continued theatrical appeal of a darker, long-running anime property, while MOBILE SUIT GUNDAM HATHAWAY The Sorcery of Nymph Circe showed that serious mecha science fiction can also attract substantial audiences.
Even Galaxy Express Milky☆Subway: Local Train to the Theater represents an important trend: smaller and unconventional anime projects can move from short-form online or television releases to the big screen when they develop a strong audience.
The result is a much broader anime movie landscape than the traditional idea of a theatrical hit being limited to one or two giant franchises.
From cute character-driven adventures to mystery, dark fantasy, mecha, family animation, video-game adaptations, and experimental short-form projects, 2026 is showing just how wide the audience for animated movies has become.
And with Chiikawa currently leading the 2026 Japanese box office at ¥15.84 billion, the year’s biggest anime-movie story may be coming from one of the smallest-looking heroes of them all.
