The Anti-Japanese Movement refers to a series of social and political actions in the United States and other countries that opposed Japanese immigration and influence, particularly during the late 19th and early 20th centuries. This movement was fueled by economic competition, racial prejudice, and geopolitical tensions, especially during events like the Second Sino-Japanese War and World War II. In the U.S., the movement led to discriminatory laws, such as the Chinese Exclusion Act of 1882 and the Immigration Act of 1924, which severely restricted Japanese immigration. The movement also manifested in public sentiment, resulting in violence and social ostracism against Japanese communities, particularly on the West Coast.
