February 1908 made the Gentlemen`s Agreement fully effective. The agreement was replaced by the Immigration Exclusion Act of 1924. On the west coast, intense anti-Japanese sentiment developed. U.S. President Theodore Roosevelt did not want to upset Japan by passing laws banning Japanese immigration to the United States, as had happened with Chinese immigration. Instead, there was an informal “gentlemen`s agreement” (1907-8) between the United States and Japan, with Japan ensuring that there was very little or no movement to the United States. The agreements were reached by US Secretary of State Elihu Root and Japanese Foreign Minister Tadasu Hayashi. The agreement prohibited the emigration of Japanese workers to the United States and repealed the segregation order of the San Francisco School Board in California, which had humiliated and angered the Japanese. The agreement did not apply to the territory of Hawaii, which at the time was treated as separate and separate from the United States.
