Sansei (三世, "third generation") is a Japanese and North American English term used in parts of the world such as South America and North America to specify the children of children born to ethnic Japanese in a new country of residence. The nisei are considered the second generation; grandchildren of the Japanese-born immigrants are called Sansei; and the fourth generation yonsei. The children of at least one nisei parent are called Sansei. Sansei are usually the first generation of whom a high percentage are mixed race, since their parents were usually born and raised in America themselves.
