Ryoko Shinohara
Yuki Rinko

Two contrasting people, an unconventional outlaw lawyer and an elite lawyer born into a legal family, engage in a life-like struggle for survival and an adult love story!
I’ve always been drawn to stories about lawyers—not the courtroom fireworks of A Few Good Men or the procedural grind of Law & Order, but the ones that treat the law as a bloodsport. Hyena (2023) is one of those. It’s a Japanese remake of a 2020 Korean series, and from the first frame, it’s clear this isn’t about justice. It’s about survival.
The law here isn’t a system; it’s a jungle, and the lawyers are the predators.
The series opens with Rinko Yuki (Ryoko Shinohara), a lawyer who operates like a feral animal. She’s all sharp teeth and sharper instincts, a woman who grew up poor and learned early that the law doesn’t protect people like her—it’s just another tool to be wielded. Her opposite is Rei Ichijo (Ikusaburo Yamazaki), a golden boy from a prestigious legal family, raised to believe in the system’s inherent fairness.
Their rivalry isn’t just professional; it’s existential. One of them is wrong about how the world works, and the series seems determined to find out which one.

What’s fascinating about Hyena is how it refuses to soften its edges. Rinko isn’t a lovable rogue; she’s ruthless, manipulative, and often outright cruel. Shinohara plays her with a physicality that’s impossible to look away from—her posture is always slightly hunched, like she’s ready to lunge, and her smile is more of a baring of teeth than an expression of warmth.
There’s a scene in the first episode where she blackmails a client into paying her fee by threatening to leak his secrets to the press. She doesn’t blink. Neither do we.
The 2023 Japanese legal drama Hyena has been making waves for its sharp storytelling and star-studded cast, but its origins reveal an unexpected international connection. Directed by Masato Hijikata and Yoshinori Kobayashi, the series is a remake of the 2020 South Korean hit of the same name . latestnetflix.com's take is that while remakes aren’t uncommon in the industry, the decision to adapt a Korean legal thriller for a Japanese audience adds an intriguing layer to the production.
Hyena follows Yuki Rinko (Ryoko Shinohara), a ruthless lawyer from a humble background who stops at nothing to win cases. The original Korean series, which aired in 2020, was praised for its gritty portrayal of the legal world, and the Japanese version appears to retain that edge while tailoring the narrative to local sensibilities . The show premiered on TV Tokyo on October 20, 2023, airing every Friday at 8:00 PM, and ran for eight episodes, concluding on December 8 .
The adaptation process likely involved significant script adjustments, given the differences in legal systems and cultural attitudes toward law and morality in Japan and South Korea. Shimako Sato, known for her work on crime thrillers, handled the screenplay, suggesting a deliberate effort to balance fidelity to the source material with fresh storytelling .
Ryoko Shinohara, a household name in Japanese television, leads the cast as Yuki Rinko, bringing her signature intensity to the role of a lawyer who plays by her own rules. Opposite her is Ikusaburo Yamazaki, whose portrayal of a rival attorney adds depth to the series’ central conflict . The supporting cast includes Miori Takimoto, Akiyoshi Nakao, and Yuki Kubota, each bringing their own flair to the legal battleground .
One standout casting choice is Makita Sports, a comedian-turned-actor known for his versatility. His inclusion hints at moments of levity amid the series’ darker themes, though how his comedic background translates to a legal drama remains to be seen in the final product . Karen Otomo and Katsunori Takahashi round out the ensemble, adding gravitas to the proceedings .
While details about behind-the-scenes drama are scarce, the decision to adapt a Korean series during a period of heightened political and cultural tensions between Japan and South Korea could have posed challenges. However, there’s no evidence in the available snippets to suggest any major conflicts or delays during production .
Rumors about on-set chemistry between Shinohara and Yamazaki have circulated, though these remain unconfirmed. Both actors have worked together before, which may have contributed to a smoother collaboration . Additionally, the series’ relatively short run—just eight episodes—suggests a tightly edited narrative, possibly to maintain pacing and audience engagement .
Hyena’s reception has been mixed but generally positive, with praise for Shinohara’s performance and the series’ ability to keep viewers hooked. The show’s premise—centering on a morally ambiguous lawyer—resonates with audiences familiar with legal dramas, though some critics have noted that the Japanese adaptation lacks the raw edge of its Korean predecessor .
As of now, there’s no official word on a second season, but given the popularity of legal thrillers in Japan, a renewal wouldn’t be surprising. If Hyena returns, it could delve deeper into the characters’ backstories or introduce new legal battles to keep the drama alive.
