"Was already covered in Midway 1976.

Interesting fact. The Jap Americans in Hawaii were never put in internment camps. They were too important in the function of Hawaiian life and couldn't be spared. Just on the West coast. So Heston's future in-laws were never "interned" so the scene makes no sense(unless it was done in San Diego where the Pacific fleet were originally based)

You are partially correct. There was no interment camp in Hawaii in 1942 because of the reason you stated. The FBI only detained who they thought were leaders of Pro-Japan factions.
However, Honouliuli was opened in 1943 and detained 170 Japanese Americans.

My recollection was that it happened in San Diego, but the Internet agrees with you.

While training in San Diego, Tom had met Haruko Sakura (Christina Kokubo), a Nisei student at San Diego State University and the two intend to marry. Wanting to seek the approval of her parents, Haruko goes to see them in Hawai'i, where she and her parents are promptly rounded up by the FBI and interned.
