The 30-year-old Japanese actress and model has been steadily pushing her image away from pure fashion-girl territory. She did a (non-nude) sex scene in Sensei’s Pious Lie back in 2024, then gave fans a shower scene with some side boob in Honshin last year. Now she’s gone further.
In the South Korean crime film Tazza: The Song of Beelzebub (the fourth entry in the long-running Tazza gambling series, released in Korea on September 23), Miyoshi appears to have done her first full nude sex scene. A grainy photo of a theater screen has been circulating online showing her with costar Byun Yo-han. It looks like she briefly flashes her surprisingly full breasts and nipples despite her usual slender frame.
This wasn’t a total surprise. The director later talked about the bed scene in interviews, noting that Miyoshi was cool about the nudity when asked how far she was willing to go — she basically said she was fine with all of it. She plays a yakuza-linked femme fatale named Kaneko who helps design a global gambling circuit. Miyoshi is popular in Japan, but she’s arguably even bigger in other parts of Asia (she speaks fluent Korean), which explains the casting.
As she settles into her thirties, she’s clearly comfortable raising eyebrows. Between revealing outfits at fashion events, a sexy back tattoo, and now this, the former innocent-looking model is leaning hard into more adult roles. The Tazza series itself has a history of nude scenes (Kim Hye-soo and Shin Se-kyung both went there in earlier films), so the franchise isn’t shy about this stuff either.
Whether the circulating screenshot is 100% confirmed or still a bit blurry is up for debate, but the reports and director comments line up. Miyoshi fans who’ve been waiting for her to fully commit to a nude sex scene seem to be getting what they wanted.
