Nisei follows Issei
Nisei (二世, "second generation") is a Japanese-language term used in countries in North America and South America to specify the ethnically Japanese children born in the new country to Japanese-born immigrants (who are called Issei). The Nisei are considered the second generation, and the grandchildren of the Japanese-born immigrants are called Sansei, or third generation. (Ichi, ni, san are Japanese for "one, two, three"; see Japanese numerals.)History
Internment
When the Canadian and American governments interned West Coast Japanese citizens, Japanese American citizens, and Japanese Canadian citizens in 1942, neither distinguished between American/Canadian-born citizens of Japanese ancestry (Nisei) and their parents, born in Japan but now living in the U.S. or Canada (Issei).
