Japanese American history began in the late 19th century when the first Japanese immigrants arrived in the United States, primarily seeking work in agriculture and railroads. By the early 20th century, communities formed, particularly in states like California. These immigrants faced challenges, including discrimination and restrictive laws, but they contributed significantly to American society through farming, business, and cultural exchange. During World War II, the situation for Japanese Americans changed dramatically. Following the attack on Pearl Harbor, the U.S. government forcibly relocated and interned around 120,000 Japanese Americans, many of whom were U.S. citizens. This period remains a significant chapter in Japanese American history, highlighting issues of civil rights and resilience.
