Demon Slayer: Tanjiro and friends didn’t just slay demons—they slayed Japan’s box office records.
Demon Slayer: In a plot twist more shocking than Zenitsu staying calm for five minutes, Demon Slayer: Kimetsu no Yaiba – Infinity Castle has officially carved its way to #4 on Japan’s all-time box office chart—and it only took one month. That’s right, folks: swords, emotions, and upper-rank villains are once again proving to be a deadly combo… for the competition.
The Numbers: Demon Slaying and Record Breaking
In just 30 days, Infinity Castle earned more yen than Muzan has mood swings. With fans pouring into theaters like Inosuke into a fight, the film has now overtaken some of the country’s biggest cinematic heavy-hitters. Sources say ticket sales skyrocketed due to a mix of jaw-dropping animation, powerful storytelling, and the sheer need to emotionally suffer together in Dolby Surround Sound.
What’s the Secret to Its Success?
Besides the usual mix of:
- Sword-fighting choreography so sharp it could slice onions (and your feelings),
- Emotional flashbacks that require mandatory tissue boxes,
- And villain monologues that deserve their own Oscar campaigns,
It’s also thanks to a passionate fanbase willing to buy tickets faster than Tanjiro can sniff out danger.
Also, limited-edition merch. Let’s be honest: that doesn’t hurt.
Tanjiro, The Box Office King We Didn’t Know We Needed

If this keeps up, Tanjiro might need to add “film industry icon” to his résumé—right between “demon-slaying prodigy” and “professional brother protector.” Some insiders are even speculating that Infinity Castle could sneak up further in the rankings if fans continue their noble mission of repeat viewings (a.k.a. suffering beautifully for the 4th time in IMAX).
Final Thoughts: The Only Thing Higher Than the Stakes Is the Revenue
In a world full of cinematic giants, Demon Slayer: Infinity Castle has proven that anime films aren’t just for niche audiences anymore—they’re big business with big swords, big emotions, and even bigger box office numbers.
So what’s next? Global domination? A musical adaptation? Tanjiro-themed popcorn buckets? (Actually, yes to that last one—please make it happen.)
One thing’s for sure: Demon Slayer isn’t just slaying demons—it’s slaying expectations. And frankly, we’re here for every dramatic sword swing and tear-stained flashback.
