In many ways Japan seems like a paradise. Crime free, almost, 70%+ forest coverage, technologically advanced but still respect for long-standing cultural traditions. It's unrivalled social cohesiveness comes at the cost though of a lack of diversity. For example, I read somewhere it gets less than 100 asylum seekers a year.
I'll clarify that image by tell you they roughly get 9000 asylum requests a year according to the Japanese Government themselves [1]. They are however extremely reluctant in accepting any of the requests, which is what I assume you were speaking about.
To some I can imagine that's quite a shock and horror, for some, it's a dream.
"Japan accepted just three refugees in the first half of 2017 despite receiving a record 8,561 fresh asylum applications, the government said on Tuesday"
"Only four refugees were accepted in the first half of 2016, when fresh asylum applications totaled 5,011, the Justice Ministry said."
