Is living in Japan conceptually all that different from living in America?

I know the question sounds weird since there’s a very obvious difference in setting and culture and the like, but hear me out:

I’ve always wanted to move to Japan my entire life. I visited years back, but it’s very much not the same as living there. The thing is, as I grow older the lines start blurring (especially with YouTube and technology allowing us to “be in Japan” vicariously with first person live videos), and I start feeling like… conceptually living here or there isn’t really all that different. We eat, sleep, work, play games, all doable regardless of setting, and if I think about it, I feel like I’d essentially “feel” the same way in either place, internally.

I’m curious to those who are living there now, how accurate is my assessment? And what am I misinformed about? Thanks in advance!
