This is true for anywhere outside of a select few Western countries, most of the world's population still identifies along ethnic lines. Actually many in the West do too although it isn't official policy in these countries and has become taboo to say it out loud. But a lot of people still think it nonetheless. Anyway, it's not really Japan specific. I'm not sure why people always say this about Japan when other Asian countries have an even lower immigrant population. In Taiwan it's just over 1%. In Mainland China it's even much lower. Korea has slightly immigrants than Japan but it's no where near levels of Australia or the US. There's a weird obsession with Japan in Western countries and Japanese culture and politics often get stereotyped without people actually understanding much about it. The assumption that it's unusual for a country not to have (uncontrolled) mass immigration is in itself an amusing one to me.
