> Additionally, Japan has a very clear and straightforward process to convert HSP Visa (Highly skilled visa) to a permanent residency.
I mean, that's true as far as it goes, but HSP is one special visa amongst many, and they're not all so easy. Also, Japan is currently in the middle of its own dramatic restructuring of the immigration system related to HSP, including a number of new requirements that would drive critics of the US system to apoplexy (i.e. language fluency requirements).
Overall, the Japanese system looks a lot more conservative than the US one, though the sanity and consistency level is far higher.
