The first Japanese American to reside permanently in America Kanaye Nagasawa was a samurai from 1864 Edo era isolationist Japan. He left Japan in secrecy at 19 as part of a group on a secret mission to learn science and technology from the West. He eventually settled in Sonoma county, California, and set up the wine industry in the region. BBC series Rediscovered America tell his story and the story of the Japanese Americans in the US.
