The Ryukyuan religion is the indigenous belief system of the Ryukyu Islands. While specific legends and traditions may vary slightly from place to place and island to island, the Ryukyuan religion is generally characterized by ancestor worship (more accurately termed "ancestor respect") and the respecting of relationships between the living, the dead, and the gods and spirits of the natural world. Some of its beliefs, such as those concerning genius loci spirits and many other beings classified between gods and humans, are indicative of its ancient animistic roots, as is its concern with mabui (まぶい?), or life essence.
Over time, Ryukyuan religious practice has been influenced by Chinese religions (Taoism, Confucianism, and folk beliefs), Buddhism and Japanese Shinto. One of its most ancient features is the belief onarigami (おなり神), the spiritual superiority of women derived from Amamikyu, which allowed for the development of a noro (priestess) system and a significant following for yuta (female mediums). This differs greatly from Japanese Shinto where men are seen as the embodiment of purity.
Ryukyuan religion, with its focus on demonstrating respect of and reverence toward ancestors, is naturally based in the family home. The oldest female relative acts as a primary celebrant, officiating rituals concerning ancestors, household gods and those family members who live both in and outside the home. Daily incense offerings are made and prayer "reports" are delivered aloud, in which each family member is described for the benefit of the incorporeal being addressed. The oldest female relative is also responsible for cleaning and upkeep of the buchidan (ancestors altar), hinukan (hearth god and his home on the hearth), and furugan (bathroom god).
