The term 'SANSEI' is a Japanese-American term used to describe a grandchild of Japanese immigrants. It is derived from the Japanese word for 'third generation'. Sansei are typically born in the United States and are the grandchildren of Japanese immigrants who came to the US during the early 20th century. They are the first generation of Japanese-Americans to be born and raised in the US, and often have a unique cultural identity that combines both Japanese and American cultures.
