Which Japanese anime film became the highest-grossing Japanese film of all time in 2025 with nearly $780 million worldwide?

The Japanese anime film that made history in 2025 by becoming the highest-grossing Japanese film of all time with a worldwide box office nearing $780 million is Demon Slayer: Infinity Castle. This cinematic event continued the phenomenal success of the Demon Slayer franchise, which has captivated audiences globally with its compelling storyline and stunning animation.

Released in July 2025 in Japan and later internationally, Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle adapted a crucial arc from the popular manga series by Koyoharu Gotouge. The film follows the Demon Slayer Corps in their climactic battle against the formidable Muzan Kibutsuji and the Upper Rank demons within the treacherous Infinity Castle. Its release was highly anticipated, building on the immense popularity of the anime television series and its predecessor film, Demon Slayer: Mugen Train, which itself was a record-breaker in 2020.

The film's incredible box office performance, including strong showings in North America and other international markets, solidified the Demon Slayer franchise's position as a global cultural phenomenon. It surpassed previous records set by acclaimed films like Spirited Away (Review) and even its own franchise's Mugen Train, showcasing the ever-growing international appeal and commercial power of Japanese animation, particularly when backed by the high-quality production of studios like Ufotable. The success of Demon Slayer: Infinity Castle underscores a significant shift in the global film landscape, where anime now regularly competes with major Hollywood blockbusters.
