Chie Shinohara’s long-running shojo manga Red River will receive its first television anime adaptation, with the premiere scheduled for Summer 2026. The adaptation arrives 24 years after the manga concluded, marking a rare late-stage revival of a 1990s shojo property.
On Feb 15, the official website and X account of the upcoming series confirmed the adaptation with a teaser visual and commemorative artwork. In his statements, the original author Shinohara appeared deeply moved by the Red River manga adaptation initiative. He hoped that people who are unfamiliar with the manga would also enjoy the anime, along with the fans from the original serialization.
Chie Shinohara/Shogakukan
Originally serialized in Shogakukan’s Shojo Comic from 1995 to 2002, Red River (Sora wa Akai Kawa no Hotori) blends historical fantasy, romance, and political drama. Tatsunoko Production, the studio behind popular animated series Space Ace and Gatchaman, will be producing the adaptation.
However, the announcement hasn’t detailed the specific release date and cast for the anime. The Red River anime production committee has yet to announce the streaming platform and countries of release as well.
Red River Shojo Revival in an Isekai-Dominated Era
The Red River anime adaptation aligns with the continued industry appetite for narratives with isekai elements. However, the series is not an isekai in proper specification, and predates the modern isekai narratives, popularized by titles such as Re:Zero and That Time I Got Reincarnated as a Slime.
Isekai genre primarily focuses on the protagonist traveling into a fantasy world, whereas, in Red River, the protagonist is transported into an original historical empire. To keep the narrative historically grounded, the team includes two historical supervisors: Kimiyoshi Matsumura and Daisuke Yoshida.
Unlike many contemporary entries built around power-fantasy mechanics, Red River’s protagonist navigates her journey through a historically grounded political plotline. The series follows Yuri Suzuki, a modern Japanese teenager transported to the 14th-century BC Hittite Empire, where she becomes entangled in royal succession conflicts and wartime struggles.
Production details released alongside the announcement confirmed that Kosuke Kobayashi will helm the series, while Yoriko Tomita, writer of My Dress-Up Darling (2022-2025) and The Elusive Samurai (2024), will handle the series composition. Kenji Fujisaki, who has worked on the famed Detective Conan: The Fist of Blue Sapphire (2019) and Vampire Hunter D: Bloodlust (2000), will design the characters for the Red River anime adaptation.
Despite serialization ending in 2002, Red River has continued its legacy, with a strong 8.27 score on the MyAnimeList platform. The manga is compiled into 28 tankōbon volumes and has sold more than 20M copies in circulation, as of 2026. It also won the 46th Shogakukan Manga Award in the shojo category.
The narrative and reception are much similar to The Twelve Kingdoms, a politically driven isekai with a female protagonist, which achieved critical recognition in the early 2000s for its world-building and mature themes. Whether Red River can replicate that cross-generational impact will depend on production execution and global distribution strategy.
