Most Japanese immigrants wanted to live in America permanently and came in family groups, in contrast to chinese immigration of young men, most of whom soon returned to China. They have assimilated to American social norms, as on clothing. Many joined the methodical and Presbyterian churches.   Japanese immigrants did not arrive in the United States until the 1890s. At that time, the Western United States, and in particular California, had developed an anti-Asian tradition that had its roots in the gold rush of 1849. The first American heritage of Issei was the hatred and fear of Asians, caused by the virulent anti-Chinese crusade in California, where the majority of Chinese immigrants had settled. The anti-Chinese movement, inspired primarily by economic competition and largely limited to organized work, quickly developed racist subtones and received, in the last decades of the 19th century, at least passive support from the overwhelming majority of the population of the Western United States.  Tensions had increased in San Francisco, and since Japan`s decisive victory over Russia in 1905, Japan has demanded fair treatment. The result was a series of six notes communicated between Japan and the United States from late 1907 to early 1908.
The immediate cause of the agreement was anti-Japanese nativism in California. In 1906, the San Francisco Board of Education passed a decree requiring children of Japanese descent to attend separate and separate schools. At that time, Japanese immigrants made up about 1% of California`s population, many of whom had immigrated in 1894 under a treaty guaranteeing free immigration from Japan.   Despite the apparent paper barrier of the gentlemen`s agreement, the Japanese continued to arrive in the United States and the Japanese-American population continued to grow both through the immigration of “photo marriages” and the birth of Nisei children. To escape the hostility in Northern California, where most of the former arrivals had settled, many Japanese began to settle in the Los Angeles area. Like hands lent, they were welcomed. As renters and buyers of truck and citrus gardens, they were not.
