WOWOW just locked The Aosawa Murders. Twenty years of offers, one Japanese screen first.

A Japanese mystery that spent two decades collecting adaptation offers finally has a broadcast date at home.

WOWOW is producing a six-episode live-action series from Riku Onda’s 2005 novel Eugenia, published in English as The Aosawa Murders, and will air and stream it weekly from Sunday, Nov. 8 at 10 p.m. Episode 1 is free.

Yukino Kishii takes her first WOWOW lead as Makiko Saiga, the girl who witnesses a mass poisoning at eleven and spends the next three decades letting the case rewrite how she speaks, listens, and writes.

First-look stills show her in both decades: a yellow-shirted 1980s interviewer with a pencil, and a bobbed 2000s Makiko on a flip phone when a freelance writer comes hunting for the truth.

Why this book waited

Onda’s novel won the Mystery Writers of Japan Award, has sold about 380,000 copies in Japan, and traveled in six languages after Alison Watts’s English translation.

It landed on the New York Times Notable Books list in 2020, made The Guardian’s recent crime picks the same year, and took first place in the international category of the German Crime Fiction Prize in 2022.

The plot opens on seventeen deaths by poison at a prominent family’s gathering in a coastal city, leaves a cryptic “Eugenia” note behind, and then refuses the comfort of a clean whodunit.

The question that sticks is how memory keeps damaging the living: the novelist who wrote the case into a bestseller, the blind sole survivor of the Aosawa household, and the writer still digging decades later.

Onda has said overseas and domestic offers piled up since 2005. Locking the adaptation in the book’s twentieth-anniversary year, with a complete edition also out, is the timing that finally stuck.

Kadokawa’s Takeo Kodera brought the project to WOWOW; Kadokawa Daiei Studio is producing. Chief producer Masaki Yamada has framed the draw bluntly: not “who did it,” but why people stay driven mad by the case.

The team, and the other adaptation

Naoko Adachi writes the scripts, reuniting with Kishii after NHK’s Farewell Hospital series and bringing the same multi-angle craft she showed on What Did You Eat Yesterday? and Welcome Home, Mone.

Go Furukawa leads direction; Hayato Kawai, with Disney+’s Gannibal on his résumé, also directs. Benjamin Bédusac scores.

WOWOW is calling it a stack of firsts: first Onda title on the channel, first Adachi script there, first Furukawa gig there, and Kishii’s first lead for the network.

Kishii arrives hot from Cannes Un Certain Regard title All the Lovers in the Night, plus Japan Academy Best Actress hardware for Small, Slow But Steady. She has said she read Onda since junior high, so the offer felt like joy and pressure in the same breath. Adachi’s name on the scripts is what made her willing to dive in.

Mark the other lane too. Upgrade Productions and Kadokawa pitched a separate English-language limited series from the same novel in 2024. That project is still the international remake conversation.

WOWOW’s Serial Drama W edition is the Japanese-screen first, and the network is taking international rights to TIFFCOM in Tokyo and ATF in Singapore later this year. Two pipelines can exist. Only one has a Nov. 8 start.

Our take

This is prestige crime soft power with a calendar attached, not another vertical-phone dopamine bet.

A NYT-noted Japanese mystery finally gets a home production built for long-form doubt, then goes shopping abroad while Kishii’s Cannes heat is still warm. Our Netflix Asia stack already argued Japan as durable inventory. WOWOW is making the same bet with a different shelf: literary noir that asks viewers to distrust what they saw.

Our verdict: put Nov. 8 on the watchlist, then watch which buyers show up at TIFFCOM and ATF. If the English Upgrade project moves in parallel, the novel’s real export win is dual-format demand, not a single streamer exclusive.

Memory is the product. The murder is only the door.
