Japan's system seems like Canada's, and basically the opposite of the US's: high-skill professionals easily get 5-year work visas, and can apply for permanent residence (PR) after 1 or 3 years depending on points. Having family members in the country, however, is worthless unless you marry a Japanese national.

Honestly, I don't see why a country would prefer people to bring in all their distant cousins, rather than a bunch of highly skilled professionals who contribute a lot to the economy.
