This keynote lecture is based on the fieldwork conducted in each region of Indonesia for about 5 months. Indonesia is a treasure-house of ethnic sports. However, although a few articles on Indonesian ethnic sports appeared during the Dutch colonial era, nothing have appeared since then. Later, during the late 1970s, Indonesian sports became more important in a field for study. It is impossible to study Indonesian ethnic sports without the view point of the nation states "Indonesia" because it exists as cultural policy of nation states.
