Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle demonstrates extraordinary momentum in domestic and international markets, marking another milestone in the franchise’s already impressive history. Following a robust performance during the Obon holiday period, the film’s total Japanese box office earnings have climbed to an estimated ¥22.7 billion (US$153.2 million). This figure reflects a strong 74 percent increase in weekly revenue, driven by consistent audience turnout during its fourth week of release. To date, the film has attracted 16.2 million admissions, surpassing the lifetime audience figures for both Howl’s Moving Castle and Harry Potter and the Philosopher’s Stone, and securing the position of Japan’s eighth most-watched film of all time.
Industry projections suggest that Infinity Castle is on course to surpass Your Name’s ¥25.17 billion total, which would cement its status among the top five highest-grossing films in Japanese history. This achievement would place it alongside cultural juggernauts such as Frozen, Titanic, and the record-holding Mugen Train. The latter, also part of the Demon Slayer series, became a phenomenon in 2020, grossing over ¥40 billion and redefining what an anime film could achieve in global cinema.
The film’s international rollout is proving equally impactful. In Thailand, Infinity Castle debuted with an opening day gross of more than 70 million baht (US$2.2 million). This performance positions it as one of the strongest post-pandemic launches in the country and suggests a sustained demand for high-quality anime productions across Southeast Asia. Early forecasts indicate the film could dominate the regional weekend box office, contributing to an estimated US$20 million overseas total that includes strong holdover earnings from Taiwan.
Taiwan’s reception has been particularly noteworthy. The film recorded the largest-ever opening for a Japanese production in the market, generating NT$176.7 million (US$5.9 million) over its debut weekend. This figure surpasses the opening of Mugen Train by approximately 50 percent and ranks as the fifth-highest opening in Taiwan’s box office history, behind only select Hollywood blockbusters such as Avengers: Endgame and entries from the Fast & Furious franchise. Given its trajectory, analysts expect Infinity Castle to rank among Taiwan’s top three highest-grossing Japanese films by the end of its theatrical run.
Directed by Haruo Sotozaki and produced by Ufotable, Infinity Castle serves as a multi-part cinematic adaptation of the “Infinity Castle” arc from Koyoharu Gotouge’s internationally acclaimed manga. Unlike earlier theatrical releases, such as Mugen Train, which condensed a manga arc into a single feature, this trilogy aims to provide a full, detailed retelling of the narrative’s climactic events. The first installment, subtitled Akaza Returns, premiered in Japan on July 18, 2025, distributed by Aniplex and Toho.
The film’s regional release strategy is designed for maximum impact, with August rollouts planned for Hong Kong, Malaysia, Singapore, Indonesia, Vietnam, and South Korea. Its global debut in September will cover the United States, Latin America, Europe, and the Middle East, potentially expanding its commercial footprint to rival the franchise’s earlier worldwide records. Given the early data from Asia, industry observers are closely watching whether Infinity Castle can replicate or even surpass the unprecedented success of Mugen Train on a global scale.
With robust domestic earnings, record-breaking international openings, and a carefully staged worldwide release plan, Demon Slayer: Infinity Castle appears well-positioned to become one of the defining box office stories of 2025.
