The new Demon Slayer Infinity Castle movie could become the highest grossing movie in Japan's box office history, but it's still got a Miyazaki film (and its own predecessor) to beat
As of now, Demon Slayer: Kimetsu no Yaiba – The Movie: Mugen Train is still the highest-grossing Japanese film of all time, followed by Hayao Miyazaki’s Spirited Away. But there's a chance that might change

As of this writing, we're still a few days away from the hotly-anticipated US release of Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle. But in Japan, where the movie has been out for about a month and a half, that anticipation has already turned into a cinematic event, which has in turn turned into a box office revelation. In fact, a recent report points to the possibility that Infinity Castle may soon become the most successful film in Japan's box office history...
If it can knock out its own predecessor and one of the most legendary animated films to ever hit Japanese cinemas.
The report we're talking about, specifically, is one published by Crunchyroll September 8. In it, Crunchryoll points to the fact that Infinity Castle has passed the 30 billion yen mark at the Japanese box office, one of only three films to have ever done so. Not only that, but Infinity Castle now holds the record for the fastest film to have reached that benchmark, passing it at only 46 days in the theater.
And yet, those aforementioned other two movies still hold strong above Infinity Castle's total earnings. The first of those is, unsurprisingly, another Demon Slayer movie - Demon Slayer: Kimetsu no Yaiba – The Movie: Mugen Train - which went on to pass the 40 billion yen mark at the Japanese box office, the only film to ever do so. To this day, it is the most financially successful film in the history of that box office.
Coming in just below it (but still obviously making Japanese cinematic history), was beloved Studio Ghibli film Spirited Away, which made a reported ¥31.68B when it came out in 2001. That record was held for nearly two decades, until Mugen Train came along and blew everyone away.
So will Mugen Train's follow-up take its coveted spot? Well, that's a question only time can answer, but at the speed with which Infinity Castle is raking in box office cash (Mugen Train took 59 days to reach ¥30B as opposed to Infinity Castle's 46), it's at least a distinct possibility. In other words, get ready to update those wikipedia pages, anime fans.
Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle slashes into US theaters September 12.
