Yakuza games have always been known for having a wealth of mini-games to distract you, and Like a Dragon is no different.
Theres plenty for you to do in Yokohamas Isezaki Ijincho, but its also a considerably larger place than Kamurocho, so it can take some time to get your bearings on just whats available in.
