Tensions in San Francisco had increased, and since Japan`s decisive victory, Japan sanitized against Russia in 1905, demanding equal treatment from Japan. 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.   Japan was prepared to restrict immigration to the United States, but was seriously violated by san Francisco`s discriminatory law, which specifically targeted its people. President Roosevelt, who wanted to maintain good relations with Japan as a pole opposed to Russian expansion in the Far East, intervened. While the U.S. ambassador reassured the Japanese government, Roosevelt summoned the mayor and the San Francisco school board to the White House in February 1907 and convinced him to end segregation and promised that the federal government itself would address the issue of immigration. On February 24, the gentlemen`s agreement was reached with Japan in the form of a Japanese memo, in which it was agreed to deny passports to workers wishing to enter the United States and to recognize the right of the United States to exclude Japanese immigrants with passports initially issued to other countries. March 13, 1907 followed the formal withdrawal of the San Francisco School Board`s decision. A final Japanese note, dated February 18, 1908, made the gentlemen`s agreement fully effective.
The agreement was replaced by the Immigration Exclusion Act of 1924. Let me begin first for the laborious thoroness and admirable temperament with which you have gone in the case of the treatment of the Japanese on the coast . I had a conversation with the Japanese ambassador before leaving for Panama; read to him what I had to say in my annual message, which he obviously liked very much; and told him that, in my view, the only way to avoid permanent friction between the United States and Japan was to limit as much as possible the movement of citizens from each country to each other to students, travellers, businessmen and others; As no American worker tried to enter Japan, the need was to prevent all immigration of Japanese workers – that is, from the Coolie class – to the United States; that I really hoped that his government would prevent his coolies, all their workers, from coming to either the United States or Hawaii. He was strongly committed to this view and said that he had always opposed Japanese coolies going to America or Hawaii… I hope my message will calm their feelings for the government to tacitly stop all immigration of coolies into our country. Anyway, I will do my best to achieve it. The increase in Japanese immigration, which was to replace some marginalized Chinese agricultural workers, has met with concerted opposition in California. To appease Californians and avoid an open break with Japan`s emerging world power, President Theodore Roosevelt negotiated the diplomatic agreement in which the Japanese government took on the responsibility of drastically limiting Japanese immigration, especially that of workers, so that Japanese children could continue to attend integrated schools on the West Coast. However, family migration could continue, as Japanese men, with sufficient savings, could bring wives through arranged marriages (“pictured wives”), their parents and minor children. As a result, the Japanese-American population was more gender-friendly than other Asian-American communities, and continued to grow through natural increases, which led to increased pressure to end immigration and further reduce residents` rights.
