UfotableDemon Slayer: Infinity Castle has roared into cinemas across Japan with a historic box office debut that crushed the record once held by Mugen Train.
Infinity Castle, the newest film in the hit anime series, has stormed into Japanese theaters with a 9.3/10 rating on IMDb and glowing early reactions from fans praising its animation, emotion, and scale.
The film marks the start of the series’ climactic arc and is being hailed as one of Ufotable’s best productions to date. With the story picking up after the Hashira Training arc and launching the first of a trilogy that will close out the main saga, expectations were sky-high, and the box office numbers didn’t disappoint.
Demon Slayer Infinity Castle breaks records
According to Crunchyroll, Infinity Castle earned ¥7.31 billion, about USD 49.55 million, in just four days, with over 5.16 million tickets sold. Its opening three-day total hit ¥5.52 billion ($37.42 million), setting a new record for the biggest opening weekend in Japanese box office history.
It’s already the second highest-grossing film in Japan for 2025, trailing only Detective Conan: The One-Eyed Flashback. Premium formats also boosted the total, with Deadline reporting $3.5 million came from IMAX screenings alone.
While Infinity Castle has shattered opening weekend records, it’s still far from catching Demon Slayer: Mugen Train’s lifetime total in Japan. Mugen Train remains Japan’s all-time highest-grossing anime film, with a total of ¥40.4 billion worldwide (about $507 million USD).
Infinity Castle premieres in Southeast Asia starting August 12, hits Latin America, Australia, and the Middle East on September 11, and lands in the US, UK, Canada, and India on September 12. European markets follow soon after, with France on September 17 and Germany on September 18.
