Japanese broadcaster Wowow has unveiled its first-look images and casting details for a six-episode live-action adaptation of Riku Onda's best-selling mystery novel The Aosawa Murders (published in Japan as Eugenia). The series stars Yukino Kishii, who gained international recognition through her Cannes Un Certain Regard title All The Lovers In The Night, in what marks her first role for the broadcaster. The announcement matters as another high-profile literary adaptation from Wowow, following a string of internationally-facing Japanese drama projects, and brings a celebrated crime novel to screen for the first time.

Kishii plays Makiko Saiga, who witnessed a mass poisoning at a prominent family's home as an eleven-year-old and later wrote a novel about the case, portraying the character across two timelines in her twenties and forties. The script is written by Naoko Adachi, with Go Furukawa as lead director alongside Hayato Kawai, known for Disney+'s Gannibal. The series premieres on 8 November 2026, airing weekly on Wowow. Onda's 2005 novel has sold 380,000 copies in Japan, been translated into six languages, won the Mystery Writers of Japan Award and Germany's international crime fiction prize, and was named a New York Times Notable Book in 2020.
