  Mugen Train vs. Infinity Castle: A New Legacy

  Mugen Train still holds the title of Japan’s highest-grossing film with ¥40.43 billion ($275M). However, Infinity Castle is outpacing its early performance despite facing a more competitive box office landscape.

  Powered by stunning animation, emotional storytelling, and a passionate global fanbase, Infinity Castle is shaping up to be a once-in-a-generation cinematic phenomenon.

  Franchise & Cultural Impact

  Created by Koyoharu Gotouge, Demon Slayer has sold over 200 million manga copies globally. First serialized in Weekly Shōnen Jump from 2016 to 2020, it has become a cultural icon on par with Naruto, One Piece, and Dragon Ball.

  Infinity Castle adapts the manga's final arc across a trilogy, with fans eagerly awaiting the next two installments. If Part 1 is any indicator, this trilogy may redefine the ceiling for anime cinema.
  
  

  Cultural Phenomenon in the Making

  More than just an anime film, Demon Slayer: Infinity Castle Part 1 is a cinematic event rewriting the rules for Japanese movies in the global arena. Its early dominance in Japan and growing hype overseas suggests it may become the highest-grossing anime film of all time, further cementing Demon Slayer’s place in modern pop culture history.
