Tokyo, 14 September 2025 — Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle, the first part of the much-anticipated anime trilogy adapting the manga’s final arc, has stormed the Japanese box office and is making waves internationally. With record-breaking opening day and weekend figures in Japan, the film is on track to claim new milestones in global anime film history.
Domination at Home
Released in Japan on July 18, 2025, Infinity Castle wasted no time setting new marks. Its opening day grossed ¥1.64 billion (approx. US$11.11 million), accompanied by 1.15 million admissions—making this the highest single day opening in Japan’s box office history. Over its first three days, the film raked in approximately ¥5.52 billion (US$37 million) from 3.84 million viewers. When the fourth day—a public holiday—was included, its total shot up to ¥7.31 billion (US$49.55 million) from around 5.16 million tickets sold.
This performance has elevated Infinity Castle above many high-water marks: it’s broken single-day and opening-weekend records, and it has overtaken Spirited Away to become the second highestgrossing film in Japan, now trailing only Mugen Train among domestic box office giants.
Overseas Momentum
Globally, Infinity Castle is showing strong commercial potential. Its U.S. and UK release on September 12, 2025, has been tipped to bring in an opening weekend that could challenge long-standing anime records set by films such as Pokémon: The First Movie. Projections vary, but estimates suggest a range between US$35 million and US$60 million in its U.S. debut. Meanwhile, markets across Asia and beyond, including Taiwan, Thailand, and India, have shown robust box office performance following earlier releases.
What Makes Infinity Castle a Phenomenon
Several factors appear to be fueling its success:
- Loyalty and excitement from an established fanbase for Demon Slayer.
- The scale and ambition of the adaptation: Infinity Castle is not just another anime film—it’s part one of a trilogy capturing the emotional and action-heavy crescendo of the source material.
- High production values, sweeping action sequences, and visual spectacle, which have drawn praise not only from fans but also from critics in Japan.
- Strategic rollout across international markets with strong advance ticket sales.
Challenges & Outlook
While the mood is bullish, the film’s global record will depend on continued box office strength outside Japan. U.S. and UK numbers will be closely watched, especially relative to other anime hits. The rise in ticket prices, competition from other releases, and market saturation in certain territories are risk factors. Additionally, sustaining momentum past opening weekends often proves difficult for anime films in Western markets.
Still, Infinity Castle appears well-positioned. If projections hold, it could surpass Mugen Train globally as the highest-grossing anime film ever, or at least come tantalisingly close. The film’s performance is more than commercial—it’s a barometer of anime’s growing influence on the global cinematic landscape.
