Mamoru Hosoda's Oscar-Qualifying 'Scarlet' Drops New Trailer Featuring Theme Song 'Hateshinaki'

Acclaimed director Mamoru Hosoda has generated fresh excitement for his upcoming animated feature, Scarlet, by unveiling a captivating new promotional video. This latest preview not only offers a deeper look into the film's ambitious visual landscape but also prominently features the central theme song, "Hateshinaki," setting a powerful emotional tone for the highly anticipated release.

Adding a layer of unique personal involvement, the track is performed by Mana Ashida, the talented actress lending her voice to the titular heroine, Princess Scarlet. Furthermore, the creative synergy runs deep, as the lyrics for "Hateshinaki" were penned by Hosoda himself, reinforcing his singular vision across both the narrative and sonic dimensions of the project. Produced by the renowned Studio Chizu, Scarlet is positioned as a sweeping fantasy action adventure.

The film promises a time-bending narrative centered on a medieval princess driven by a fierce desire for retribution following the devastating murder of her father. The film delves into heavy, complex themes, primarily exploring the destructive nature of revenge and hatred, juxtaposed against the possibility of liberation and forgiveness. This thematic echo is loosely drawn from the foundations of Shakespeare's classic tragedy, Hamlet.

Despite its complex plot drawing some mixed critical feedback. Reviewers have praised the sheer ambition of the world-building while noting occasional structural convolution. Nevertheless, Scarlet has already made significant waves internationally. Earlier in 2025, the film achieved major recognition with screenings at elite film festivals, including Venice, Toronto, and New York, successfully qualifying it for potential Oscar consideration.

Fans in Japan can mark their calendars for November 21, 2025, when Scarlet opens in theaters, including premium IMAX formats. However, the wait for North American audiences has been slightly extended, with the U.S. theatrical debut now slated for early 2026.

Complementing Hosoda’s storytelling is an impressive creative team, featuring a score composed by Taisei Iwasaki and a vocal cast anchored by Mana Ashida and Masaki Okada. As a major highlight of the 2025 anime calendar, Scarlet stands as a testament to Hosoda’s enduring commitment to unique artistic expression and profound storytelling.
