Demon Slayer Infinity Castle Part 1, Akaza Returns was finally released in Japan on July 18, 2025, and fans were beyond excited. The movie didn’t just meet expectations; it broke several box office records on the very first day.
Theaters were full, tickets sold out in minutes, and fans had strong emotional reactions. This clearly shows that Demon Slayer is still one of the most loved and powerful anime series today.
Demon Slayer Infinity Castle Box Office Collection: Day 1
On its first day in Japan, Demon Slayer: Infinity Castle broke several box office records. The movie earned over ¥1.7 billion, which is around $12 to $13.4 million in U.S. dollars. This is more than what Mugen Train made on its first day, which was about ¥1.26 billion.
Some fans on Reddit even believe the real numbers could be even higher. According to Filmibeat, the movie made about $13.4 million, clearly beating Mugen Train’s opening.
When compared to other big anime movies, Mugen Train still holds the record for the highest total earnings, with over ¥40 billion in Japan and $507 million worldwide. But on day one, Infinity Castle had a stronger start.
Other popular anime movies like Jujutsu Kaisen 0, Suzume, The Boy and the Heron, and Detective Conan earned much less in comparison. The fan response was incredible. Midnight screenings sold out in just 10 minutes across 24 theaters. Many fans waited in long lines, full of excitement.
