The Demon Slayer hype train just doesn’t stop! After Mugen Train smashed every record imaginable, fans knew the Infinity Castle arc was going to be huge. The movie dropped in Japan on July 18, 2025, kicking off the final big battle of the series. This is only the first part of the Infinity Castle saga, and ufotable once again took charge of the animation (yep, the studio that makes every frame look like art). TOHO handled the Japan release, while Crunchyroll and Sony brought it overseas.
Here’s the fun part: Infinity Castle reportedly had a budget of around $20 million. Pretty modest when you compare it to Hollywood blockbusters — but the returns? Absolutely massive.
Japan: The film opened to a jaw-dropping $49.7 million (¥7.3 billion) in just four days. As of now, it’s pulled in over ¥31 billion (~$213 million), making it Japan’s second-highest-grossing film ever, right behind Mugen Train. Spirited Away? Yeah, it got pushed down the list.
Worldwide: Globally, the movie has crossed $550 million+, with some reports even pushing it closer to $800M. In North America alone, it scored about $70 million on opening weekend — the biggest anime opening ever there.
So yeah… from a $20M budget to hundreds of millions worldwide? That’s not just success, that’s a box office takeover.
The Good Stuff: Fans can’t stop praising the animation and fight scenes — ufotable really went all out to make every frame look like pure art. It’s the kind of spectacle you just have to see in a theater.
The Not-So-Good: A lot of people felt the movie was too heavy on backstories. Since Infinity Castle dives into the pasts of both the Hashira and the demons, some viewers thought it slowed down the pacing and stretched the runtime. As one reviewer put it:
“The film cannot commit to being an action movie due to the overuse of flashbacks … the pacing suffers.”
Overall though, the reception has been overwhelmingly positive. If you’re a Demon Slayer fan, this movie delivers.
