Rio de Janeiro (state)
People of African descent are numerous, particularly in the metropolitan area of the capital city. Those of mixed-race ancestry (tri-racials, "mulatos", and some "caboclos" and "cafuzos") make up the majority of the population in many cities. The city of Itaguaí was considered a Japanese colony in the 20th century, but many of the Asian Cariocas that once lived there moved overseas (most of them to Japan) as well to other Brazilian states like São Paulo.
