Located in a peaceful marsh lies the home of the Ninja Dogs of Koga. Dappled with abandoned teahouses in which the ninjas rest in, the area is fenced by a rich forest and a small lake in which become sanctuaries for the young, old, sick and healthy. The Koga Village, once sworn enemies of the Iga ninjas, have been transformed from the cannibalistic dark ninjas into the more dominant good-willed warriors, closely tied with Ohu. It is located far into the east, isolated from most of the higher powers.
