Prof. Makoto Koike with Uma Ratu (blogspot.com)
Umbu Haharu is the name given to Professor Makoto Koike by the villagers of Wunga Village in East Sumba when he was doing his ethnographic research for his doctoral dissertation in December 1985–June 1988. The effort was done to delve into the culture (courtship, marriages, arts, dances and social manners) and beliefs (religious, myth and legends) of the village. “Wunga is the first Kampong in Sumba, mythical and interesting,” Makoto said.
In an interview with CRCS at Elvin Hotel in East Sumba, Makato disclosed that he chose Sumba because he had developed interest on Sumba while doing a library research on Eastern Indonesia for his Master Degree thesis at Tokyo Metropolitan University. This post-graduate work in the same university is a concretization of his desire of visiting Indonesia, especially Eastern Indonesia.
