The box office momentum of Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle continues to accelerate, with the film crossing the $200 million milestone worldwide. The first entry in the planned Infinity Castle trilogy has already broken records across Asia, outperforming the landmark success of Mugen Train in several markets.
According to industry estimates, Infinity Castle earned approximately ¥3.6 billion ($24.5 million) internationally over the recent weekend, bringing its overseas total to about ¥5 billion ($34 million). The film’s explosive performance in Southeast Asia—already surpassing Mugen Train in Thailand, Vietnam, Malaysia, and Indonesia—has fueled its rapid climb. Globally, the cumulative box office now stands near ¥31 billion ($209 million), positioning the film well ahead of expectations.
In Japan, Infinity Castle remains dominant as it moves into its fifth weekend. The film grossed an estimated $12.3 million over the three-day frame, a 4 percent increase from the previous weekend, while Sunday’s Obon holiday added another $3.7 million. With a total of ¥25.86 billion ($175.5 million) and more than 18.6 million admissions to date, it has overtaken Disney’s Frozen to become the fourth highest-grossing film of all time in Japan. In admissions, it is projected to surpass Your Name within the coming week, securing a place among the top six most-watched films in Japanese history.
Directed by Haruo Sotozaki and produced by Ufotable, Infinity Castle – Part 1: Akaza Returns adapts one of the most dramatic arcs of Koyoharu Gotouge’s manga. The project is designed as a multi-film narrative, echoing the approach taken with Mugen Train. Released domestically on July 18, 2025, the film is set to expand its international rollout through August in select Asian markets, before reaching audiences in the United States, Latin America, and Europe in September via Crunchyroll and Sony Pictures Releasing.
While critical responses have been mixed, audience enthusiasm has propelled the film to the top of the 2025 box office in Japan and made it the country’s fourth highest-grossing film in history. With its trajectory still outpacing Mugen Train by more than 10 percent after 31 days, analysts suggest that Infinity Castle could ultimately finish above ¥35 billion ($240 million), or even approach ¥40 billion ($270 million) if its late run proves strong.
For a franchise that has already redefined modern anime cinema, Infinity Castle appears poised to extend Demon Slayer’s legacy as one of the most dominant cultural forces in contemporary Japanese entertainment.
