not really, it's hard to describe shenmue, yakuza does have some similarities, like how you can roam around the world, do mini games, the combat style where you start in this mini scenario and have to fight a lot of dudes, but that's it. Shenmue is more like a daily life simulator in a sandbox world, you need to find a job, go to sleep at some time, rent a room, go to stores and buy random things, play video games, talk to random all the random people in the world about your quest or things..etc etc, there is an actual timer in the game and the weather and people will change and behave depending on that, there is no other game similar to shenmue.
