Takayuki Yagami , "Tak" for short, is a character in Sega's 2018 action-adventure video game Judgment, which is a spin-off from the Yakuza game series. Yagami is a former defense attorney who resigns after a client he successfully defended kills their partner. Three years later, Yagami is a private detective in his own "Yagami Detective Agency" and investigates a serial killer who gouges out their victims' eyes. The character returns in Lost Judgment as he investigates a criminal accused of both sexual harassment and murder. Yagami is voiced by Takuya Kimura in Japanese and by Greg Chun in English. Yagami's physical appearance is also based on Kimura.

Yakuza, known in Japan as Ryū ga Gotoku and also known as Like a Dragon in recent series entries to align with its Japanese name, is a video game franchise created, owned and published by Sega. It incorporates elements of the action-adventure, beat 'em up, and role-playing genres.
