Nisei followed by Sansei
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.)Cultural profile
Generations
Japanese Americans and Japanese Canadians have special names for each of their generations in North America. These are formed by combining one of the Japanese numbers corresponding to the generation with the Japanese word for generation (sei 世). The Japanese-American and Japanese-Canadian communities have themselves distinguished their members with terms like Issei, Nisei, and Sansei which describe the first, second and third generation of immigrants. The fourth generation is called Yonsei (四世) and the fifth is called  Gosei (五世).  The Issei, Nisei and Sansei generations reflect distinctly different attitudes to authority, gender, non-Japanese involvement, and religious belief and practice, and other matters. The age when individuals faced the wartime evacuation and internment is the single, most significant factor which explains these variations in their experiences, attitudes and behaviour patterns.The term Nikkei (日系) encompasses all of the world's Japanese immigrants across generations. The collective memory of the Issei and older Nisei was an image of Meiji Japan from 1870 through 1911, which contrasted sharply with the Japan that newer immigrants had more recently left. These differing attitudes, social values and associations with Japan were often incompatible with each other. In this context, the significant differences in post-war experiences and opportunities did nothing to mitigate the gaps which separated generational perspectives.
