Demon Slayer Infinity Castle Is the Biggest Anime Movie Ever but It Still Lost in Japan

Here's a number that should melt your brain a little: 39,710,774,400 yen. That's what Demon Slayer: Infinity Castle has earned at the Japanese box office as of March 2, 2026, across 228 days and 27.1 million admissions. The film is officially entering its "last run" this spring before leaving theaters for good. Globally, it's even crazier. Infinity Castle pulled in over $778 million worldwide during its initial run, making it the highest-grossing anime film of all time. It surpassed records in market after market and proved that anime isn't just a niche thing anymore. It's a full-on box office force.

So Close, Yet So Far

But here's the wild part. Despite all of that, Infinity Castle still couldn't beat Mugen Train in Japan. The 2020 film earned over 40 billion yen domestically, a record that seemed almost destined to fall. Infinity Castle came painfully close at 39.7 billion but is wrapping up just short of the mark. It's a strange kind of loss. The movie that became the biggest anime film in global history couldn't top its own franchise's earlier entry on home turf. Mugen Train had the once-in-a-lifetime pandemic recovery factor working in its favor, where people were desperate to get back into theaters. That's a tough thing to replicate. Still, being the second highest-grossing Japanese film ever is hardly something to be disappointed about.

The timing couldn't be better. Just as Infinity Castle enters its final stretch, Aniplex (Sony) and Kadokawa announced the formation of ANIMEC, a brand new company dedicated entirely to anime film distribution and promotion. The name combines "anime" and "cinema," and it's a clear signal that these two industry giants are going all-in on theatrical anime.

What ANIMEC Actually Does

The idea is straightforward. ANIMEC will handle everything from nationwide theatrical premieres to special screenings of TV anime. It's meant to be a bridge between content holders, theater operators, and fans, maximizing the reach of every anime release under its umbrella. For Demon Slayer specifically, this is massive. Aniplex already manages the franchise's production and distribution, and with ANIMEC in the mix, the remaining two Infinity Castle films are positioned for an even more aggressive global push. We're talking optimized release strategies, better marketing coordination, and a company whose entire reason for existing is to make anime films bigger. This isn't coming out of nowhere, either. Sony acquired a 10% stake in Kadokawa back in early 2025, becoming its largest shareholder. ANIMEC is the natural next step of that partnership, and Demon Slayer is clearly the franchise they're building it around.

Let's get this out of the way. Demon Slayer: Infinity Castle Part 2 is not releasing in 2026. Ufotable confirmed this in a recent promotional overview, and while it's not exactly shocking given the production scale involved, it still stings for fans who were hoping for a faster turnaround. The good news? Infinity Castle is returning to North American and UK theaters starting March 6, 2026 for special screenings. If you missed it the first time, or if you just want to experience Akaza's fight on the big screen one more time, this is your shot.

The Wait Will Be Worth It

Part 2 is expected to land sometime in 2027, and if Infinity Castle is any indication, the wait will be worth it. The Infinity Castle arc covers some of the most intense material in the entire Demon Slayer manga, and Part 1 only scratched the surface. The Upper Moon confrontations ahead are going to be absolutely massive. With ANIMEC now handling the distribution side, Part 2 and Part 3 are set to get the full theatrical treatment on a scale we haven't seen before. Demon Slayer isn't just ending. It's going out as the biggest anime franchise in theatrical history.
