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 The agreement prohibited the emigration of Japanese workers to the United States and repealed the segregation order of the San Francisco School Board in California, which had humiliated and angered the Japanese.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 was then treated as separate from the United States. The agreements remained in effect until 1924, when Congress banned all immigration from Japan.  A similar anti-Japanese atmosphere in Canada also led to the Hayashi Lemieux Agreement, also known as the “gentlemen`s agreement of 1908,” with substantially similar clauses and effects. Kraemer and Barrows v. Jackson.
 One source indicates that gentlemen`s agreements “undoubtedly exist,” but that their use has declined sharply.  In the automotive sector, Japanese manufacturers agreed that no production vehicle would exceed 276 hp (206 kW; 280 hp); the agreement ended in 2005.  German manufacturers limit the maximum speed of high-performance sedans (sedans) and station wagons to 250 km/h (155 mph).    When the Suzuki Hayabusa motorcycle exceeded 310 km/h (190 mph) in 1999, fears of a European ban or crackdown prompted Japanese and European motorcycle manufacturers to agree on an upper limit of 300 km/h (186 mph) at the end of 1999.
