Club Stardust is a host and cabaret club located in the Kabukicho neighborhood of Tokyo, Japan. The club was founded in the late 1990s, and Shintaro Kazama helped the club's owner Hiroshi Kazuki to build the club; the club became an important base of operations for Kazama's adoptive son Kazuma Kiryu during the 2005 Tojo-kai civil war, during which Kiryu fought off Shimano-gumi extortionists at the club. During the 2006 Tojo-Omi war, the host Yuya Miyake became the temporary manager of the club while Kazuki recovered from his injuries at the hands of Kang Jinwu, and the club was attacked by Ryuji Goda and his Goryu-kai during the Omi Alliance's invasion of Tokyo. In 2009, the Nishikiyama-gumi captain Kazuya Hasebe attempted to force Kazuki to sell the club to him for a few months for use as his family's base of operations for an upcoming war with the Kazama-gumi, but Kiryu thwarted this extortion by beating down all of the yakuza. By 2016, the club was bought by the Jingweon Mafia, and Yuya resigned and found work as an ordinary salaryman. The Korean mobsters added a basement section with more sexualized services, while also creating a fighting ring to provide a show for the audience.
