In the late 1970s, a few Christian (Dutch Protestant) missionaries began to live among the Korowai. Dea Sudarman, an Indonesian anthropologist, made several documentary films on the Korowai for Japanese television in the 1980s. In 1993, a film crew documented an anthropological study in the Dayo village area by the Smithsonian Institution of Korowai treehouse construction and the practice of cannibalism as a form of criminal justice. This resulted in the film "Lords of the Garden". In 1996 a local Christian community was established, the members of it mainly originating from the neighbouring Kombai people. For a long time the Korowai have been considered exceptionally resistant to religious conversion; however, by the end of the 1990s the first converts to Christianity were baptized. In the autumn of 2003, a small team of Bible translators from Wycliffe/SIL moved to Yaniruma.
