The Hiroshima Kamaris were a pre-flash baseball team from Hiroshima. Not much is known about what they did pre-Flash, but now they stay at Camp Kamari, located near the base of the Rising Sun Warriors. It is rumored that the abandoned bus on the map belonged to them.
The Hiroshima Kamari's were a baseball team from Hiroshime. It was still traveling from city to city as the war was going on. They were stranded by the Flash and took control of the recreation center.
The Kamaris currently control the recreation center and have occupied it since the Flash occurred, they have remained out of the faction battles. The recreation center is made out of scrap, except for the fence.
