What compromise did the governments of the US and Japan reach on immigration?

In 1907, the United States and Japan reached an informal agreement known as the "Gentlemen's Agreement," which aimed to resolve tensions regarding Japanese Immigration. Under this compromise, Japan agreed to limit the issuance of passports to laborers seeking to immigrate to the U.S., while the U.S. agreed to treat Japanese immigrants already in the country with respect and not to impose discriminatory laws against them. This arrangement effectively curtailed Japanese immigration without formal legislation, reflecting the diplomatic efforts of both nations during that period.
