Answer:
In the early 1900s, Japan said it would restrict the number of Japanese citizens emigrating to the United States if the United States did not impose restrictions on Japanese immigration and did not discriminate against Japanese citizens already living in America. This was called the Gentlemen's Agreement of 1907.
Step-by-step explanation:
The Gentlemen's Agreement of 1907 was an informal agreement between the United States and Japan in which the United States agreed to not impose restrictions on Japanese immigration, and Japan agreed to not allow immigration to the United States. The agreement aimed to alleviate tensions between countries. The Gentlemen's Agreement ended when in the United States the Immigration Act came into force in 1924, which banned all Asian migrants from the United States.
In this agreement, Japan undertook not to issue passports to people seeking to enter the United States. In return, the United States pledged to accept the Japanese already residing in the country and to allow their relatives to migrate. The United States also pledged to end the discrimination against Japanese children in California schools.
