In comparison, the visa (technically, "residency permit") scheme in Japan (widely viewed as a xenophobic, anti-immigrant country) is tied to the person. You get sponsored in by an employer in a field, and then your residency is tied to you being employed in that field. You can instantly turn around and quit that job and find another one in the same field. Policy is you have 30 [or was it 60?90? something like that] days to find a new job or voluntarily forfeit your residency. You will only need to prove that though the next time you renew your residency permit.

They also make it very easy for skilled labour to immigrate. You just need a degree in your field and a sponsoring employer. There are no quotas, no need for the employer to prove they tried to find a local at above market rates, fees aren't onerous, etc.

The xenophobic view comes partly from how there aren't many skilled workers who want or can work in Japan (relatively low wages, Japanese language requirement) but mostly from their reluctance to allow unskilled labour in (which the US accepts via illegal immigration and Europe accepts via refugees)
