Japanese internment camps sprung up during World War Two. These camps relocated 110,000 Japanese Americans on the West Coast. The Japanese attack on Pearl Harbor was a factor in the development of these camps.
Japanese Americans
Not anymore, but there were in the Second World War. They were known more commonly as internment camps during those times; the term concentration camp was created by the Nazis in the 1930's.
I think you are referring to the WWII Japanese internment camps. After Pearl Harbor, it was thought that Japanese-American citizens could not be trusted, so they were rounded up and forced to live at various "camps" around the U.S. until the war was over. See the Related Links below.

Fearing that Japanese living in the United States would help Japan, the government gathered up almost 120,000 Japanese-Americans and resident Japanese aliens and placed them in internment camps. Some people remained in the camps for over three years.
Japanese internment camps were set up in the USA in WW2 to contain Japanese Americans. An obvious con of the camps were that they infringed on the rights of innocent American citizens. A pro is that they kept non Japanese Americans from panicking.
During World War II, Japanese Americans were treated extremely unfairly. Specifically, President Roosevelt signed an executive order which called for all Japanese Americans in the US to be rounded up and moved into camps.
Both the US and Canadian governments excluded those of Japanese ancestry from the areas of the Pacific coast. In many cases they were interned in isolated camps for up to three years during World War II. While not concentration camps, they were definitely not comfortable for the internees, most of whom were American citizens although the children of Japanese immigrants.
The Japanese Americans that were put in internment camps faced the racism of whites. They were afraid of the hatred of those around them that made threats.
There was a fear that Japanese/Americans, even second or third generation, would act as an internal threat to America during the second World War with Japan.
