For one of the projects in New Jersey, I worked with Atos team in Brazil. One of the colleagues in Brazil who spoke fluent Portuguese had a Japanese sounding last name, on checking with him he confirmed that he was of Japanese origin.
Later on I did some research and found that Brazil is home to largest Japanese population outside Japan. There are more than a million people of Japanese origin in Brazil. Brazilian Jiu-Jitsu developed with the help of Japanese immigrants to Brazil. Majority of Japanese Brazilians are concentrated in Sao Paulo.
