琉球神道
Uruma is home to numerous sites associated with the Ryukyuan religion, many of which are located on the Yokatsu Islands. Hamahiga Island is located approximately northeast of Kudaka Island, which is considered the holiest place of the Ryukyuan religion. The tombs of Amamikyu and Shinerikyu are located on Hamahiga. Amamikyu and Shinerikyu are worshipped at their tombs, and the "noro" priestess of Higa conducts prayers at the beginning of the year at the sites. The forests of the southeast tip of Hamahiga are home to a cave that is considered one of the residences of Amamikyu and Shinerikyu; a stalactite in a cave at the site is a center of worship for numerous children. Nearby are other holy sites related to Shinerikyu, Maitreya, and Nirai Kanai (most notably the Miruku Gate and Mount Yugafu).
