The gentlemen`s agreement of 1907 () was an informal agreement between the United States of America and the Empire of Japan紳協 which did not allow Japanese immigration and Japan to no longer emigrate to the United States. The aim was to ease tensions between the two Pacific states. The agreement was never ratified by the U.S. Congress and was replaced by the Immigration Act of 1924. 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 agreed to limit the number of passports it provided to male workers and domestic workers to 400.
Four classes of immigrants would still be allowed to enter Canada: returning residents and their wives, children and parents; Immigrants employed by Japanese residents in Canada for personal and domestic services; Canadian government-approved workers; and contracted farm labour by Japanese landowners in Canada. Although no specific legislation has been adopted to enforce the quota, the agreement has resulted in a significant reduction in Japanese immigration. In the year following the agreement, only 495 Japanese immigrants arrived in Canada.  Although the agreement limited the number of adult men who could enter Canada, it did not provide for restrictions on the wives of Japanese immigrants. After the introduction of the quota, a large number of Japanese women began to migrate to Canada as « image brides. » Japanese men in Canada would choose brides based on photos sent by relatives to Japan. After registering her marriage in Japan, the bride was granted a passport to Canada. The arrival of more Japanese women facilitated a natural increase in Canada`s Japanese population.  Concessions were agreed in a note that, a year later, consisted of six points. The agreement was followed by the admission of Japanese students to public schools.
The adoption of the 1907 agreement spurred the arrival of « image marriages, » women who were closed remotely by photos.  The creation of distant marital ties allowed women who wanted to emigrate to the United States to obtain a passport, and Japanese workers in America were able to earn a partner of their own nationality.  As a result of this provision, which helped to reduce the gender gap in the Community, from a ratio of 7 men per woman in 1910 to less than 2 to 1 in 1920, japan`s population continued to grow despite the immigration restrictions imposed by the agreement. The gentlemen`s agreement was never enshrined in a law passed by the U.S. Congress, but it was an informal agreement between the United States and Japan, which was implemented by unilateral action by President Roosevelt.
