For over 100 years, Japanese immigrants and Japanese Americans have called San Diego County home. Attracted to the warm climate and economic opportunities, Issei (first-generation Japanese immigrants) drifted into San Diego in the 1880s and introduced effective new fishing techniques that contributed to the growth of this industry. From the Tijuana River Valley on the border with Mexico to Oceanside in North County, Japanese American families started small truck farms in the first decades of the 20th century, developing techniques to improve crop production. Surviving the heartbreak of evacuation and incarceration during World War II in desert internment camps, San Diegans returned to rebuild a vibrant community after the war.
