The wait is almost over for fans eagerly anticipating the next chapter in the Demon Slayer saga. The upcoming Infinity Castle movie has been gaining massive buzz since it was first announced, and now an official trailer date has been confirmed. The main trailer for Demon Slayer: Infinity Castle Part 1 is set to premiere on June 28, marking a major milestone for the film’s rollout.

The trailer will debut during a special television broadcast of the Demon Slayer: Mugen Train arc in Japan. This highly anticipated reveal is timed perfectly to reignite excitement ahead of the film’s theatrical debut in Japan on July 18, 2025. While international fans may have to wait slightly longer, it is expected that the trailer will be uploaded online shortly after its television airing, likely appearing on YouTube and official anime platforms. For US audiences, the movie is slated for release on September 12, 2025.

Infinity Castle marks the beginning of Demon Slayer’s final arc and is being adapted into a trilogy of films. This format aims to deliver an immersive, cinematic experience that fully captures the scale and intensity of the original manga’s climactic storyline. While some fans may prefer the faster pace of a seasonal anime format, the movie approach promises higher production value, particularly crucial for animating the complex and visually rich Infinity Castle setting.

The first installment will follow the Demon Slayer Corps as they enter the Infinity Castle, where they are immediately separated and forced to face off against Muzan’s strongest demons. If the film remains faithful to the manga, viewers can expect emotionally charged battles, including Shinobu’s confrontation with Doma and Zenitsu’s long awaited duel against his former comrade Kaigaku. These scenes are some of the most impactful moments in the series and are sure to be enhanced by the movie’s cinematic treatment.

For fans worldwide, the confirmation of the trailer’s release is a much needed update and a signal that the journey to the series' finale is well underway. With breathtaking visuals, powerful character arcs, and a story that continues to raise the stakes, Infinity Castle is set to deliver one of the most talked about anime movie events of the year.
