is studying in japan worth it?

I want to go to med school after my bachelors, but have wanted to live in japan since i was young. i saw mixed reviews looking it up briefly, but would i be able to finish my last 3 years of my undergrad studies in japan and still move on to post-grad in the U.S.? as an american, the cost of living there and uni prices are a lot more affordable (remote job and help from parents) than it is here, but would this even be feasible or make any practical sense?

edit to clarify
i want to get my bachelors in japan, then go to med school back home in america 🙂
