Demon Slayer: Kimetsu no Yaiba Infinity Castle Ranks as 10th Highest-Grossing Film in Japan Within 17 Days
In a record-setting box office achievement, Demon Slayer: Kimetsu no Yaiba Infinity Castle has officially become the 10th highest-grossing film of all time in Japan after just 17 days in theaters. As of August 3, 2025, the film has earned 17.63 billion yen (approximately US$119.26 million), driven by over 12.55 million ticket sales across Japan, according to official sources. The anime film also secured its place as the highest-grossing movie of 2025 at the Japanese box office, surpassing major titles and solidifying the Demon Slayer franchise’s ongoing popularity.
Infinity Castle Surpasses Expectations at the Japanese Box Office
Released on July 18, 2025, Demon Slayer: Kimetsu no Yaiba Infinity Castle quickly climbed the charts. Within just over two weeks, it overtook Detective Conan: One-eyed Flashback, which previously held the top spot for the year with a box office total of 14.4 billion yen. With its current performance, Infinity Castle also overtook Bayside Shakedown 2, which had remained in Japan’s Top 10 since 2003, to take the number ten position in the all-time rankings.
This latest installment in the Demon Slayer film saga now holds the distinction of being the seventh highest-grossing anime film in Japanese history. It currently trails behind major Studio Ghibli classics such as Howl’s Moving Castle (19.6 billion yen) and Princess Mononoke (20.1 billion yen).
Building on the Legacy of Mugen Train
The box office trajectory of Infinity Castle draws comparisons to 2020’s blockbuster success, Demon Slayer: Kimetsu no Yaiba – The Movie: Mugen Train. Notably, Mugen Train reached the same milestone—10th highest-grossing film in Japan—in 17 days as well, but with lower earnings of 15.79 billion yen during that period. Infinity Castle has outperformed Mugen Train by nearly 2 billion yen within the same timeframe, underscoring the continued strength of the Demon Slayer brand.
