Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle opened in Japan with a historic start. It has become the franchise’s most successful release since 2020’s record-smashing Mugen Train.
Demon Slayer: Infinity Castle arc has set multiple records in its just first four days. It saw massive success in Japan, with ticket demand so high that websites crashed and most showings sold out within hours. The first chapter of the trilogy surpassed the newly released Superman movie in Japan, which opened to a disappointing $2.5 million.
Demon Slayer: Infinity Castle Box Office
Released on July 18, 2025, Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle Arc Chapter 1: Akaza Returns drew over 1.15 million moviegoers on its first day, pulling in ¥1.65 billion (around $11.13 million). That figure marks the highest single-day box office gross in Japanese cinema history.
The momentum continued through the weekend. From July 18 to 20, Infinity Castle brought in $37.3 million from 3.84 million tickets sold. Including the Marine Day holiday on Monday, the four-day total climbed to $49.4 million from over 5.16 million admissions.
Its debut has now gone down as the biggest four-day opening ever in Japanese box office history.
Breaks IMAX Opening Record
The film also set a new domestic record for IMAX screenings. In its first three days, Infinity Castle brought in $3 million from 59 IMAX screens. By Monday, the total climbed to $3.5 million, averaging $48,000 per screen.
It now ranks as the biggest IMAX opening in Japan, surpassing both Mugen Train and Studio Ghibli’s The Boy and the Heron.
Final Arc Adaptation Begins with Part 1
Directed by Haruo Sotozaki and produced by ufotable, Demon Slayer: Infinity Castle adapts the final arc of Koyoharu Gotouge’s manga. The story follows the Demon Slayer Corps’ final mission inside Muzan Kibutsuji’s Infinity Castle.
The film features fan-favorite voices returning to their roles — Natsuki Hanae as Tanjiro, Akari Kito as Nezuko, Hiro Shimono as Zenitsu, and Yoshitsugu Matsuoka as Inosuke.
Rather than a TV season, the final arc is being adapted as a three-part film series. Infinity Castle – Part 1: Akaza Returns is the first installment, with sequels planned for 2027 and 2029.
Global Release Scheduled for September
The international release begins September 12, 2025, in North America and other regions, distributed by Toho, Aniplex, and Crunchyroll. Following its massive performance in Japan, the film is projected to do just as well internationally.
It is projected that Infinity Castle may record an estimated global box office total of up to $700 million, putting it in the same range as major blockbusters like Jurassic World: Dominion and Man of Steel. For comparison, Mugen Train grossed over $500 million worldwide.
Early Reviews Are Overwhelmingly Positive
Fans are already praising the movie’s visuals, emotional depth, and pacing. It currently holds a 9.4/10 rating on IMDb, an early sign of its strong reception ahead of international release.
With strong ticket sales, high audience scores, and two more installments on the way, Infinity Castle is on track to become the franchise’s biggest success, and one of the highest-grossing anime films ever made.
Demon Slayer: Infinity Castle is now playing in Japan and opens internationally on September 12, 2025.
