of the citadel was occupied by a sanctuary called Kyo-no-uchi. This was a place where natural elements, such as trees and natural limestone rocks were utilized. Although Noro (priestesses) carried out a number of nature rituals (as also sometimes occurs in Shinto), the contents of the rituals and the layout of the inner part of the sacred areas remain unclear. After the war, limited religious observance continued on the site, mostly with the placement of incense sticks on places formerly considered sacred. However, restoration of the castle stopped general access to these sites, and for this reason, "Shuri Castle was resurrected, but it was destroyed as a place of worship". Investiture Contacts between the Ryukyu Islands and China began in 1372 and lasted five centuries until the establishment of Okinawa Prefecture in 1879. When a new king commenced, the Emperor of China sent officials to attend the investiture ceremony at the castle. Through this ceremony, the kingdom reiterated its ties with China, both politically, commercially, and culturally.

Then the investiture ceremony took place in the Una, where two platforms were erected between the Nanden and Seiden, called Kettei, reserved for the envoys, and Sendokudai. The imperial official recited the formula for the appointment of the new king and bowed deeply. Later, inside the castle, there was a "Feast of Investiture," followed by a "Mid-autumn Banquet", accompanied by songs and dances. This banquet was held on a temporary platform opposite the Hokuden, a platform on which the Imperial envoys stood. On the shore of Ryutan and in the castle, the "Choyo Banquet", during which a boat race and musical performances took place, was also held in the presence of the delegation. Two successive farewell banquets were then held opposite Hokuden, and finally a banquet at Tenshikan, where the
