their work ethic
See you are romanticizing the shitty aspects of Japan like a typical weeaboo. It's not "work ethic", one-up sucking-up to your bosses and squeezing people dry and fake ass bonding over drinks because your colleagues have to be your family is not "work ethic", that you give your life to a company because all that matters is the corporate climb is not "work ethic" it's garbage. Best of luck, you probably won't enjoy the worst of this disintegrated darwinian society because you'll never be considered Japanese to begin with. You guys are like transexuals but with national identity instead of what you have in your pants.
