Some Japanese scholars have pointed out that Japanese immigration laws, at least toward high-skilled migrants, are relatively lenient compared to other developed countries, and that the main factor behind its low migrant inflows is because it is a highly unattractive migrant destination compared to other developed countries.
Yet in spite of this, the number of foreign residents in Japan in recent years is very high.
This is optimistic and I hope they succeed, because every time I read an article about nuclear fusion it's always 5 to 10 years away, and I feel like I've been reading articles about nuclear fusion for the better part of 2 decades.
