Sansei is a Japanese and North American English term used in parts of the world to refer to the children of children born to ethnically Japanese emigrants (Issei) in a new country of residence, outside of Japan. The nisei are considered the second generation, while grandchildren of the Japanese-born emigrants are called Sansei. The fourth generation is referred to as yonsei. The children of at least one nisei parent are called Sansei; they are usually the first generation of whom a high percentage are mixed-race, given that their parents were (usually), themselves, born and raised in America.
The grandchildren of these Japanese-Brazilian (Nipo-brasileiros) immigrants are called Sansei.
