Demon Slayer: Kimetsu no Yaiba Infinity Castle First Movie Becomes Fastest Film to Reach 10 Billion Yen in Japan
Since its release in Japan, Demon Slayer: Kimetsu no Yaiba Infinity Castle has been shattering box office records, surpassing expectations and making history within the Japanese film industry. The movie, produced by renowned anime studio ufotable, achieved the remarkable feat of reaching 10 billion yen in gross revenue in just eight days. This accomplishment establishes Infinity Castle as the fastest film ever to cross this significant milestone in Japan.
Record-Breaking Box Office Performance
According to official reports from the Demon Slayer: Kimetsu no Yaiba franchise’s social media accounts, as of July 27, 2025, Infinity Castle accumulated 10 billion yen within only eight days of release. This performance surpasses the previous record held by the critically acclaimed Mugen Train movie, which reached 10 billion yen in ten days back in 2020. Building on this momentum, by the tenth day, Infinity Castle grossed an impressive 12.87 billion yen (approximately US$87.03 million) across Japan, with ticket sales reaching 9.1 million seats.
These numbers position Demon Slayer: Kimetsu no Yaiba Infinity Castle as the 29th highest-grossing film in Japanese box office history. The movie surpassed the lifetime gross of the original 1993 Jurassic Park film, confirming its status as one of Japan’s biggest cinematic successes. Furthermore, Infinity Castle currently holds the position of the second-highest-grossing movie in Japan for 2025, second only to Detective Conan: One-eyed Flashback, which has amassed a total of 14.59 billion yen.
Comparisons to Previous Demon Slayer Releases and Box Office Trends
Industry data from Oricon highlighted Infinity Castle’s swift rise to the 10 billion yen mark as unprecedented, making it the fastest film in Japanese history to reach such earnings. Despite this impressive achievement, the previous Demon Slayer film, Mugen Train, continues to hold the record for the biggest second weekend by a large margin, earning 3.13 billion yen compared to Infinity Castle’s second weekend figure of 3.09 billion yen, as reported by Kogyo Tsushin.
The release timing has also played a significant role. Infinity Castle opened during Japan’s summer holidays, providing a more extended and steadier box office performance in contrast to Mugen Train, which premiered in October 2020. This strategic release window helped maintain audience attendance over a longer period.
