Despite the work of organizations like the Japan Society, many groups still opposed Japanese immigration to Canada, especially in B.C.'s fishing industry during the 1920s and 1930s. Prior to the 1920s, many Japanese labourers were employed as pullers, a job that required them to help the net men row the boats out to fish. The job required no licence, so it was one of the few jobs for first-generation Japanese immigrants who were not Canadian citizens. In 1923, however, the government lifted a ban on the use of motorboats and required that pullers be licensed. This meant that first-generation immigrants, known as , were unable to get jobs in the fishing industry, which resulted in large–scale unemployment among these . Second-generation Japanese Canadians, known as , and who were born in Canada, began entering the fishing industry at a younger age to compensate for this, but even they were hindered as the increased use of motorboats resulted in less need for pullers and only a small number of fishing licences were issued to Japanese Canadians.
