Kamurochō is a fictional district of Tokyo from Sega's Yakuza media franchise. It is modelled after Kabukichō, Tokyo's renowned red-light district and entertainment precinct situated in Shinjuku ward. Like its real world counterpart, there are many retail shops, izakaya, restaurants, and mizu shōbai establishments like host and hostess clubs, soaplands, and nightclubs within the district. Kamurochō has appeared as the primary setting in most Yakuza main series titles and several spin-off games, as well as adaptations of the franchise in other media.

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.
