Highlights of Tamagusuku Castle Ruins
A sacred site on the Agari-umaai
Tamagusuku Castle Ruins has played an important role in Okinawan history.
It is best known as the fourteenth – and therefore final – prayer site on the Agari-umaai, the sacred pilgrimage that has continued since the days of the Ryukyu Kingdom.
The Agari-umaai begins at Sonohyan Utaki in Shuri, passes through Yonabaru, Sashiki and Chinen, and comes to a close here at Tamagusuku Castle Ruins.
Standing here, it is easy to let your thoughts drift back to the old days of Ryukyu.
The Sun Gate
The Sun Gate, through which the rising sun shines on the summer solstice, is the symbol of Tamagusuku Castle Ruins.
Rather than being built up from blocks, this unusual gate was hollowed out of a single natural boulder, giving it a distinctive shape that some say resembles a heart.
The view from the gate is a scenic highlight that leaves a real impression on visitors.
Amatsuzu Utaki
Within Tamagusuku Castle Ruins stands the sacred Amatsuzu Utaki.
Amatsuzu Utaki is one of the seven utaki of the Ryukyuan creation myth, and remains an important place of prayer for local people.
It lies within the main enclosure, and it is from this utaki that Tamagusuku Castle takes its alternative name, Amatsuzu Castle.
The legend that Amamikiyo built it
This castle site is said to have been built by Amamikiyo, the creator deity of Ryukyu.
For anyone interested in Okinawan history and culture, that legend is a compelling draw.
You can take in the history while letting your imagination travel back to the age of myth.
Beautiful stone walls
Another highlight of Tamagusuku Castle Ruins is the stonework, built from beautiful Ryukyuan limestone.
Weathered by time and now blending into the landscape, the walls make a strong impression.
They carry the excellence of Okinawa’s distinctive building techniques into the present.
A steep flight of stone steps leads up to the gate, and some stretches have no handrail, so wear trainers or other comfortable walking shoes.
Allow about 30 minutes
A visit to Tamagusuku Castle Ruins takes around 30 minutes.
Take your time around the highlights and let yourself sink into Okinawa’s spiritual landscape.
When planning your trip, use about 30 minutes as a guide.

The history of Tamagusuku Castle Ruins
Tamagusuku Castle Ruins occupies an important place in both the myth and the history of Okinawa.
– Roots in Ryukyuan myth
The site is said to have been built by Amamikiyo, the creator deity of Ryukyu.
In Okinawan mythology Amamikiyo is revered as the deity who created the islands, and that influence endures today.
– An important stronghold in the Ryukyu Kingdom era
Tamagusuku Castle Ruins also played an important role during the Ryukyu Kingdom period.
Its standing as the fourteenth and final prayer site on the Agari-umaai speaks to that importance.
– Architectural beauty across the ages
The site’s distinctive walls, built of beautiful Ryukyuan limestone, carry Okinawa’s own building techniques into the present.
– Value as cultural heritage
For its historical and cultural value, Tamagusuku Castle Ruins was designated a national historic site in 1987.
The castle originally consisted of three enclosures: the first, second and third.
After the war, however, the stone walls were pulled down and carried off for use as building material at the neighbouring US military base, and much of the second and third enclosures was lost. What survives in relatively good condition today is the wall of the first enclosure.
Tamagusuku Castle Ruins is a precious place where you can feel both the history and the myths of Okinawa.
Its beautiful setting and rich history leave a deep impression on visitors.
