The relationship between the United States and Japan were cordial and friendly through the 18th and 19th centuries.
After the Japanese imposed the 21 Demands (1915) against China leading to outrage in the US, Britain, and China. This led to the 1924 American Immigration law that reduced the number of Japanese immigrants allowed to enter the United States leading to rising tensions.
Tensions became even more strained in the 1930's during the Sino-Japanese War in which the Japanese and China (an ally of the United States) went to war over Japan wanting to expand its empire and claim to raw goods and materials within China. The relationship also be came more hostile after Manchurian/Mukden Incident.
The United States took it upon themselves to impose harsh sanctions against the Japanese and the export and import of Japanese goods. They also cut off Japanese oil supply- wanting them to agree to leave China.
This angered the Japanese leading to the bombing of the Pacific area (including the US Naval Base of Pearl Harbor, Hawaii). This led to the beginning of World War II.
