The Kamaiurá are an important reference in the culture area of the Upper Xingu, in which peoples who speak different languages share very similar worldviews and ways of life. They are even connected by a system of specialized trade and intergroup rituals, which have different names for each ethnic group, but which have become known (both by people within and outside the Xinguan universe) precisely by the terms used in the Kamaiurá language, such as the Kwarup and the Jawari. For general information about the Upper Xingu, see the section Indigenous Park of the Xingu.
