Udun (Ryūkyū)

Udun (御殿) is the name given to the princely houses of the Ryūkyū Kingdom, generally issued from a son of one of the kings of Ryūkyū who did not inherit the throne. The term also refers to the residences of those families, as well as to the royal residences and, by extension and often written with a different ideogram (), the royal mausolea.
