anthropology and sociology of Japanese minorities?

Question

This is not a racist question but a multicultural one. I have met many people from various backgrounds. indo-europeans, italian americans, afro americans, chino europeans etc. however i have never met a black japanese person. I am lead to believe that the japanese are not very multi cultural and therefore it is hard to be accepted into their families. therefore as there are no endogenous black people to the islands of japan, does this cultural group exist?

yes i am aware that japan went through isolation for approx. 500 yrs, this does not answer my question.

Answer 1

Japan went through a period of cultural isolation (sakoku) from 1641 until 1853. Because of this almost no foreigners were allowed into Japan - let alone to live there. Right until the end of the second world war Japan was much against any foreigners living there on a permanent basis.
Most nations with ethnic minorities are nations that were great traders in the past (or had many slaves) like Britain, Australia, the USA, Mexico, etc. Japan had neither any real trade links or foreign slaves.
So any black people living in Japan would have at very most lived there two generations - not anywhere near long enough to form a subculture.
Modern Japanese people are reasonably multicultural but still not as much as many other nations. Therefore there is no black Japanese cultural group.

Answer 2

I am not aware that black people exist in Japan in significant numbers, however you should be aware that a large group of Caucasoid native people, called Ainu, live in the northern Japanese Islands.
