In 1850, the first imported worker arrived from China. Between 1852–1887, almost 50,000 Chinese arrived to work in Hawaii, while 38% of them returned to China. Although help was needed to work the fields, new problems, like feeding, housing and caring for new employees, were created for many of the planters since the Chinese immigrants did not live off the land like Native Hawaiians, who required little support. To prevent their workforce from organizing effectively against them, plantation managers diversified the ethnicities of their workforce, and in 1878 the first Japanese arrived to work on the plantations. Between 1885–1924, 200,000 Japanese people arrived with 55% returning to Japan. Between 1903–1910, 7,300 Koreans arrived and only 16% returned to Korea. In 1906 Filipino people first arrived. Between 1909 and 1930, 112,800 Filipinos came to Hawaii with 36% returning to the Philippines.
