Set one year after the events of Yakuza 3, Yakuza 4 follows the life of Kazuma Kiryu as he interacts and attempts to survive the ever-changing criminal underworld. Kazuma is not alone in Yakuza 4 however, as he is joined by three other protagonists, each with their own missions and fighting styles.
You play as the corrupt cop Masayoshi Tanimura who specializes in aikido and kung-fu, and whose special missions involve receiving police reports and apprehending criminals on the streets. There's also the violent Taiga Saejima, whose missions involve training fighters through grueling practice sessions. Finally, Kazuma is joined by the mysterious loan shark Shun Akiyama, with his special mission set involves both building business relationships with local store owners and scouting for new hostesses at the cabaret club he owns.
Yakuza 4 was originally released in 2010 for the PlayStation 3 but is being remade for PlayStation 4.
