japan_sucks.jpgDiscrimination against Japanese came as early as the late 19th century, Asian immigrants were subject to racial prejudice in the United States. Laws were passed that openly discriminated against Asians, and most of the time Japanese in particular. Many of these laws stated that Asians could not become citizens of the United States and could not hold basic rights, such as owning land and etc. These laws were greatly hamrful to the newly arrived immigrants. since most of the immigrants were farmers they had little choice but to become migrant workers. Some say the formation of the Asiatic Exclusion League as the start of the anti-Japanese movement in California.

Anti-Japanese racism in California was becomeing even greater after the Japanese victory over Russia in the Russo-Japanese War. On October 11, 1906, the San Francisco, California Board of Education passed a regulation that said all children of Japanese descent would be required to attend racially segregated separate schools. At the time, Japanese immigrants made up approximately 1% of the population of California. Many of them had come under the treaty in 1894 which had assured free immigration from Japan.

Nanking Massacre

The Japanese invasion of China in 1931 and the addition of Manchuria was roundly criticized in the U.S. Also, american citizens outraged at Japanese atrocities, for example the Nanking Massacre. This led to calls for America to encourage Japan to leave China. These calls played a role in shaping American foreign policy. As more and more reports of Japanese actions came to the attention of the american citizens the European American population became very pro-China and anti-Japan.
