Japanese suits/uniforms are often pretty cheap (and look that way) - thus the low end “recruit suit”. They are tailored, but the level of body-fitting they are would be actively unacceptable in the US. By which I mean, everyone would think you’re gay.
On the other hand, Japan is the home of expensive high end recreations of American casual clothes - look up Take Ivy, BEAMS, nice selvedge jeans, etc.
