This was a private garden for the king to enjoy breaks in between his duties. During excavations, stalactites that were the main aspects of the garden were unearthed. Centering around this finding, rocks also unearthed within Shurijo Castle and those collected from around the prefecture were used in the restoration. The reconstruction of the garden was based on old maps and photos. It opened to the public upon completion in 2014.
Destroyed by the fire in October 2019.
