Life was hard inside the camp. The Japanese were kept in prison-like environments; being kept behind fences, barbed-wire, and guards. Inside the walls were city-like environments of Japanese people trying to go about their daily lives. Kids went to school, and Japanese adults worked. There are occasions of mistreatment by the guards to the Japanese. The board conditions where not any better, usually being to small for today's standards.

"Life in the camps had a military flavor; internees slept in barracks or small compartments with no running water, took their meals in vast mess halls, and went about most of their daily business in public. Physical mistreatment was rare, but the armed guards and the ever-present snipers in the watchtowers were constant reminders of the residents' new status. Over time, life in the internment camps began to follow its own routine. Students were sent to school every morning, and adult internees were given jobs, usually farming or maintaining the physical plant. Each camp had a governing council, and many of the institutions of normal community life—newspapers, businesses, sports teams, concerts, places of worship—grew and thrived within the barbed wire. At the same time, however, camp life worked to erode some of the most distinctive tenets of the Japanese American community. "
