Japan witnessed cinematic frenzy on July 18, 2025, as Demon Slayer: Kimetsu no Yaiba The Movie – Infinity Castle Arc Part 1 hit theaters with explosive success. With early morning lines and midnight showings across the country, the movie has already earned a spot among the year’s most momentous anime releases. This highly anticipated entry in the Demon Slayer franchise saw fans queuing at dawn, eager to experience the latest visual feast from animation powerhouse Ufotable.

Demon Slayer Infinity Castle Movie: Record-Breaking Debut in Japanese Cinemas

From its very first screenings, the demon slayer infinity castle movie shattered expectations. On July 18, TOHO Cinemas Shinjuku dedicated 11 of its 12 screens solely to the film, hosting more than 40 showings on opening day alone. Fans lined up as early as 5 a.m. to secure a spot in one of the earliest morning screenings, while midnight showings also sold out rapidly in cities like Tokyo, Osaka, Kyoto, and Fukuoka.

The fervor extended beyond the theater halls. New exclusive Demon Slayer merchandise drew fans who were just as eager to grab collectibles as they were to catch the movie. Major urban centers such as Hokkaido, Kanagawa, and Aichi also saw packed screenings, reflecting the nationwide enthusiasm for the movie’s premiere.

What Sets the Infinity Castle Arc Apart?

This arc marks a critical turning point in the story of Tanjiro Kamado and his comrades. Set inside the enigmatic, gravity-defying Infinity Castle, the film plunges audiences into a labyrinth of surreal visuals and intense emotional battles. Critics and early viewers alike are lauding the animation, with many declaring it Ufotable’s finest work to date. According to Anime Mojo, fans describe the film as a “rollercoaster of emotions,” with battle sequences so intense that they surpass even the legendary Mugen Train installment.

With intricate character development, stunning backdrops, and seamless CGI integration, the Infinity Castle movie delivers a cinematic experience that is both heart-wrenching and exhilarating.

Early Box Office Numbers Show Strong Momentum

The numbers already speak volumes. According to Filmibeat, the movie earned $1.34 million USD on its opening day in Japan alone. Given its domestic-only release at the moment, analysts predict these figures will soar once the film hits international markets in September. For comparison, Mugen Train grossed over 40.43 billion yen worldwide and remains Japan’s highest-grossing movie of all time. The new release seems poised to follow in its footsteps.

Social media buzz also plays a significant role in its early success. Japanese netizens are flooding Twitter and TikTok with emotional reactions, battle analysis, and animation breakdowns. The film’s viral appeal makes it a prime candidate for global box office dominance once it hits Western theaters.

Upcoming Global Release and Fan Expectations

Demon Slayer: Infinity Castle Part 1 is set to release in North America on September 12, 2025. Expectations are sky-high as Western fans prepare for what many are calling the anime event of the year. Given Ufotable’s global reputation and the success of previous entries in the series, ticket sales are expected to spike as soon as pre-orders open.

In anticipation of the release, Ufotable has hinted at limited-edition merchandise drops and special fan events, further increasing the hype. Fans are encouraged to follow the official Demon Slayer channels for updates on screenings, promotions, and collaborations.
