The sacred worshipping site at the front of the castle wall is called the Suimui Utaki. According to Ryukyu Kaibyaku Shinwa (Ryukyu creation myths), the sacred Suimui Utaki site was created by a god. Within the castle grounds, it is said that there were ten places of worship, including this one.
There are numerous writings related to Suimui Utaki written in the Omorosaushi, the oldest collection of Ryukyuan songs and ballads. The Suimui Utaki was restored in December of 1997.
