"Nisei" refers to the second generation of Japanese immigrants in the United States, specifically those born to Japanese parents who had immigrated to America. This term is significant in understanding the cultural and social dynamics of Japanese Americans, as Nisei individuals often navigated the challenges of balancing their Japanese heritage with American identity. During World War II, many Nisei faced discrimination and were unjustly interned in camps due to their ancestry. Despite these challenges, Nisei contributed significantly to American society, including serving in the military, where units like the 442nd Regimental Combat Team became highly decorated for their bravery and service.
