The korowai, also called the Kolufo, are a people of southeastern Papua (i.e., the southeastern part of the western part of New Guinea). They number about 3,000.[1] Until 1970, they were unaware of the existence of any people besides themselves. The tree people, Korowai and Kombai, live in the basin of the Brazza River in the vast lowland jungles. This is situated in the foothills of the Jayawijaya mountain range, which is in the southwest part of the New Guinea Island in the Indonesian province Papua (Irian Jaya). Mosquitoes and age-old rivalry forced these tribes to build houses in the tops of trees. Some of them are placed as high as 40 m. Korowai & Kombai – friendly cannibals? Korowai and Kombai used to be cannibalistic tribes. We are convinced that they still practice ritually cannibalism, but considerably less frequently. Korowai and Kombi are two of the wildest tribes on Papua. Despite that, as we gradually found out during our expeditions to this area, one can get along with them reasonably well. We have been visiting the area of these tribes for more than 10 years now. We even have some of “our friends” among the tribesmen.
