Wishes come true "Shikinamiya" / Ryukyu Hachisha

It is one of the eight Ryukyu shrines in Naha City, Okinawa Prefecture. Restrooms available are shrines that received special treatment from the Ryukyu royal government, and they are called the Ryukyu Eight Shrines.
Restrooms available has a legend in Shikina Shrine, and there is a cave behind the Main Shrine. A long time ago, a woman named Ōama Shirarei found a cave that emitted a mysterious light at night, and found a binzuru in it, and her wish came true because she deeply believed in it.
In addition, since he cured the illness of the son of the king of Ryukyu at that time, it is said that he founded the Shikina Palace there.
The Main Shrine was built around the 16th century. The pre-war building was built in the style of Sangensha and was roofed with main tiles, but it was burned down in the Battle of Okinawa, rebuilt in 1968 (Showa 43), and rebuilt in 2013 (Heisei 25) to become the current structure.
I went to Shikinagu for the first time ^^ I also went to see the cave behind the Main Shrine, but it's a pity that the gate is closed, and it seems that the cave door opens on the 1st and 15th of every month and you can go inside. It is also known as the Power Spot.
