Sanzan period The Sanzan Period (三山時代 , "Sanzan-jidai" ) is a period in the history of the Okinawa Islands when three polities, namely Hokuzan (北山 , lit. "northern mountain") , Chūzan (中山 , lit. "middle mountain") and Nanzan (南山 , lit. "southern mountain") , are said to have co-existed on Okinawa. It is said to have started during King Tamagusuku's reign (traditional dates: 1314–1336) and, according to Sai On's edition of the "Chūzan Seifu", ended in 1429 when Shō Hashi unified the island. Historical records of the period are fragmentary and mutually conflicting. Some even question the co-existence of the three polities.
