Synthesized from 4 Yomimono stories · updated Oct 3

Mayu Matsuoka's current credit is the Netflix series Downtime, in which she plays plastic surgeon Fumi Numata opposite Riisa Naka as cosmetic surgeon Rin Toyama. The two leads were announced together ahead of the series, and Netflix released 10 scene photos showing both actors performing surgery. The full eight episodes went to worldwide streaming on September 17.

Downtime is directed by Yuki Saito and written by Junya Ikegami, with a soundtrack by Yudai Bando that went to digital distribution on the same day as the series. Production was supervised by Takasu Clinic, which conducted detailed fact-checking and guidance for the cosmetic surgery depictions. Special makeup for patients was handled by a team led by Amazing JIRO, known for work on the Netflix series I'll Fall into Hell, using custom-made prosthetics applied to each actor.

After the release, coverage turned to how the series was made. Saito said he spent six months interviewing cosmetic surgery patients and doctors, a process that shaped both the script and a character. Saito also described the production demands behind Naoko Ken's role as Yuriko Sakashita, a 75-year-old widow seeking full-body plastic surgery: Ken sometimes arrived around 3 a.m. for three hours of special makeup before shooting, and Saito said a year of preparation made the makeup possible, something he called difficult for terrestrial TV dramas.

Netflix Drama Downtime Reveals Behind-the-Scenes Of Ken Naoko's Full-Body Surgery Role

Netflix's Downtime, starring Mayu Matsuoka and Riisa Naka, depicts the cosmetic surgery industry's hopes and conflicts. Ken Naoko plays Yuriko Sakashita, a 75-year-old widow seeking full-body plastic surgery. Director Yuki Saito said filming was grueling: Ken sometimes arrived around 3 a.m. for three hours of special makeup before shooting began. Ken stayed playful on set, keeping the mood light with jokes. Sakashita also has terminal cancer, so Saito told Ken to lower her voice and speak hoarsely. Special makeup was trial-and-errored to show the surgery's before-and-after. Before the operation, she looks so wrinkled that a character says, "You're all skin and bones." Cast members including Hana Amano and Yumi Adachi underwent transformations without dubbing. Saito said a year of preparation made the special makeup possible, something he called difficult for terrestrial TV dramas.
