Building on the phenomenal success of its predecessors, this latest installment in the beloved franchise has captivated audiences globally, setting new benchmarks for Japanese animation on the international stage.
The film, which premiered in Japan on July 18, 2025, and internationally on September 12, 2025, quickly demonstrated its immense drawing power. Within weeks of its global release, Infinity Castle – Part 1 amassed over $555 million at the worldwide box office, with some reports indicating totals as high as $665.8 million. This staggering performance not only secured its place as the highest-grossing anime film ever but also established it as the biggest Japanese movie of all time worldwide.
The New Apex of Anime Cinema
Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle – Part 1: Akaza Returns has not just performed well; it has redefined what’s possible for anime films in the global market. Its commanding performance includes breaking records across various territories:
- North American Dominance: The film secured the largest debut for an anime film ever in North America, with a $70 million opening weekend. It went on to become the highest-grossing anime film of all time in the United States, surpassing a 26-year record previously held by Pokémon: The First Movie.
- International Breakthroughs: Beyond Japan and North America, Infinity Castle – Part 1 achieved record-breaking anime launches in markets such as Germany ($8.2 million) and France ($8.6 million). It also became the number one anime film of all time in several countries, including Mexico, Hong Kong, India, Indonesia, Brazil, Thailand, Malaysia, and the Philippines.
- Japanese Box Office Titan: In its home country, the film quickly became the highest-grossing film of 2025 in Japan and the second-highest-grossing film in the country’s history.
This monumental success signifies a powerful shift in the global film landscape, demonstrating anime’s undeniable mainstream appeal and its capacity to compete with major Hollywood productions.
Surpassing a Predecessor: The Legacy of Mugen Train
The path to Infinity Castle‘s record-breaking run was paved by the groundbreaking success of Demon Slayer: Kimetsu no Yaiba – The Movie: Mugen Train. Released in 2020, Mugen Train was itself a cinematic phenomenon, grossing over $506 million worldwide from more than 41 million tickets sold. It famously became the highest-grossing film of 2020 globally, marking the first time a non-Hollywood production achieved this feat.
Mugen Train also set numerous records, including becoming the highest-grossing anime and Japanese film of all time worldwide, and the highest-grossing R-rated animated film ever. Its success showcased the burgeoning global appetite for Demon Slayer and set high expectations for future cinematic endeavors within the franchise.
Now, Infinity Castle – Part 1 has surpassed Mugen Train‘s impressive worldwide box office total in dollar terms, despite Mugen Train holding a higher yen gross in Japan. This highlights the increasing international reach and stronger global dollar conversions for the newer film.
Why Demon Slayer Resonates Globally
The extraordinary success of the Demon Slayer franchise, particularly its films, can be attributed to several key factors that have cultivated a dedicated global fanbase:

The decision to conclude the series with a theatrical trilogy, rather than a traditional anime season, underscores the franchise’s cinematic ambition and the significance of this final arc.
