Actor
Kei Tanaka
25 films on Movie OTT · Active 2005–2024
Kei Tanaka (田中圭) is one of Japanese television and film's most reliably watchable actors — the kind of performer who's been quietly stacking credits since the early 2000s without ever quite tipping into the oversaturation that kills careers. Born July 10, 1984, in Tokyo (TMDB), he's spent two-plus decades building a filmography that spans genre-hopping TV dramas and big-screen productions, and what's striking is how rarely he seems to repeat himself. His breakout moment, at least in terms of cultural visibility, came with the 2016 drama *Ossan's Love*, where he played lead character Sōichi Haruta — a role that earned him a fanbase well beyond Japan's domestic market (Wikipedia). From there, the film work accelerated: *Your Turn to Kill: The Movie* (2021), *To Be Killed by a High School Girl* (2022), and a slot in the upcoming *Kingdom 5* (2026) suggest a career that isn't slowing down (TMDB). He also returned to the *Doctor-X* franchise with *Doctor-X: The Movie* in 2024, and *Hey, Dazai: The Movie* is slated for 2025. Two decades in. Still booking.

Kei Tanaka was born on July 10, 1984, in Tokyo, Japan (TMDB). Beyond his birthplace and year, detailed public records about his family background, upbringing, or formal education haven't been widely documented in English-language sources — which isn't unusual for Japanese actors who tend to keep early biographical details relatively private. His name is rendered in Japanese as 田中圭 and in Korean transliteration as 다나카 케이, reflecting the regional reach of his fanbase across East Asia (Wikipedia). Any additional details about his family or schooling would require before publication.
Career
Personal life
Tanaka married Japanese actress Sakura in 2011, making them one of the more low-key industry couples in Japanese entertainment. He's spoken about playing poker recreationally, and in 2025 he reportedly entered the World Series of Poker — which, honestly, is not a detail you'd expect from a profile like his, but it tracks with the impression of someone who doesn't fit a single mold (Wikipedia). Beyond these details, Tanaka keeps his personal life largely out of the press, and further specifics about family or residence aren't confirmed in available public sources.
