I believe you are looking for the words ISSEI or NISEI or SANSEI. One is a label for those who were born in Japan and those who were born in the United States. You can learn much more about it in a book called Farewell to Manzanar. I have added some links for you to learn more about the Japanese who were interned. There are a lot of references on that site so read carefully.
See links below.
