During World War II, up to 120,000 American citizens and residents of Japanese ancestry on the West Coast were evicted from their homes and held in remote camps.
Mas Okui was one of them. He was born and raised in the San Fernando Valley in Southern California, but his father and maternal grandparents were immigrants from Japan.
Every year, Mr. Okui, 86, visits Manzanar, where he and his family were imprisoned. His purpose is to remember — and to educate.
