Have you heard of Esu Castle Ruins (Esu Gusuku), tucked away quietly in a residential area of Gushikawa in Uruma City, Okinawa?
Built on a Ryukyu limestone hill about 100 m high, this gusuku is known as an “earthen gusuku” without the grand stone walls of a castle like Shuri Castle, and it is a little-known historic site.
It is not a developed tourist attraction, but the tombs of the first to third Esu aji (local lords) and the tomb of a noro (local priestess) still remain, strongly conveying the politics and prayer of the Ryukyu Kingdom era.
This article covers the highlights, history and access information for Esu Castle Ruins in detail.

Highlights
A gusuku built on a limestone hill in Gushikawa, Uruma City
Esu Gusuku was built on a Ryukyu limestone hill about 100 m high behind Nakahara Elementary School in Gushikawa, Uruma City.
It is long and narrow, about 150 m north to south and about 60 m east to west, and makes direct use of the shape of the hill. Set on high ground with a view of the sea, it had all the conditions for a defensive stronghold.
An “earthen gusuku” with no visible stonework
Its biggest feature is that, unlike other famous gusuku, no impressive castle walls remain.
It is also known as “Esu no Tsuchi Gusuku” (the earthen gusuku of Esu). As the name suggests, no stonework remains have been found, and it is thought to have been an earthen gusuku.
A sacred site with the tombs of the Esu aji and a noro
Inside the gusuku, tombs of successive rulers still remain.
The aji tomb is said to belong to the first to third Esu aji, and the noro tomb is said to hold the aji’s sister and noro priestesses.
This shows that the gusuku was both a seat of politics and a sacred place for prayer and ritual.
The tombs of the Esu aji and the noro look like the photo above.
Esu Nundunchi
There is the Esu Nundunchi (the noro’s residence and shrine).
Next to the Esu Nundunchi there was also a Hinukan (hearth deity).
