Final answer:
Discrimination against the Japanese in the early 20th century included internment camps, voting restrictions, job quotas, and segregation laws.
Step-by-step explanation:
The discrimination against the Japanese in the early part of the 20th century included a) Internment camps, b) Voting restrictions, c) Job quotas, and d) Segregation laws.
During World War II, Japanese Americans, both immigrants and American citizens of Japanese descent, were forcibly moved to internment camps under Executive Order 9066. These camps were located in various states across the western interior of the US. Approximately 120,000 Japanese Americans, including 62% who were US citizens, were affected.
The discriminatory measures were based on the fear that some Japanese Americans might be loyal to Japan and commit acts of sabotage against the United States. However, none of the internees were found to have committed disloyal acts, and many Japanese American men even served in the US army during the war.
