The official teaser trailer, released on April 29, 2025, showcases the film's main heroine, Princess Scarlet, embarking on a quest for revenge.

This film represents a departure from Hosoda's previous works, focusing solely on fantasy elements and utilizing full CG for its visuals.

The film's release is strategically timed during the peak holiday and awards season, maximizing its potential audience.

This release under Columbia Pictures, rather than Sony Pictures Classics, suggests a bold strategy to attract a wider audience to anime films.

Leading up to 'Scarlet's' debut, three of Hosoda's previous films will be re-released in theaters in 4K format, further building anticipation.

He aims to explore the emotional complexities surrounding revenge and the choices made in desperate situations, reflecting on the fragility of life and peace.

Acclaimed director Mamoru Hosoda is set to release his new anime film 'Scarlet' in Japan on November 21, 2025, with a worldwide release following on December 12, 2025.

Produced by Yuichiro Saito and Nozom Takahashi of Studio Chizu, alongside Toshimi Tanio from Nippon TV, 'Scarlet' marks a significant collaboration between Sony Pictures and Studio Chizu, which Hosoda co-founded in 2011.

The announcement of the release date was accompanied by a teaser trailer and promotional visuals, generating excitement among fans.

The narrative follows a warrior princess in the Land of the Dead, where she confronts her sworn enemy, and promises to delve into themes of revenge and existential questions.

Hosoda's inspiration for 'Scarlet' stemmed from the societal upheaval observed during and after the COVID-19 pandemic, particularly the resurgence of global conflicts.

The trailer features intense action scenes, including duels and fireballs, positioning 'Scarlet' as Hosoda's most violent work to date.
