The Meaning of Gusuku and the Characteristics of Nakijin Castle
“Gusuku” means “castle” in the Ryukyuan language, but it was not merely a military facility. Gusuku were centers of politics, religion, and daily life, and also possessed the character of a place of prayer. Nakijin Gusuku is also believed to have served as both the residence of the King of Hokuzan and a sacred site.
The most distinctive features of Nakijin Castle ruins are its magnificent scale and beautifully curved stone walls. The entire castle complex covers approximately 37,000 square meters, making it the second largest in Okinawa Prefecture after Shuri Castle. The stone walls were built using a technique called “nozurazumi” (rough stone masonry) with Ryukyu limestone, designed to blend seamlessly with the natural bedrock.
Significance of World Heritage Registration
In December 2000, Nakijin Castle ruins were registered as a World Cultural Heritage site as part of the “Gusuku Sites and Related Properties of the Kingdom of Ryukyu.” This group of heritage sites consists of the following nine assets:
- Nakijin Castle Ruins
- Zakimi Castle Ruins
- Katsuren Castle Ruins
- Nakagusuku Castle Ruins
- Shuri Castle Ruins
- Sonohiyan Utaki Stone Gate
- Tamaudun Mausoleum

These are internationally recognized as valuable heritage sites that demonstrate the political, economic, and cultural development of the Ryukyu Kingdom. Nakijin Castle Ruins, in particular, is positioned as an important historical site that conveys the history of the Three Kingdoms period.
History of Nakijin Gusuku | From the Glory of the Hokuzan King to the Unification of Ryukyu
The Three Kingdoms Period and the Hokuzan Kingdom
Nakijin Castle appeared on the historical stage from the 13th to the 14th centuries. At that time, Ryukyu was in the “Three Kingdoms Period,” divided into three kingdoms: Hokuzan, Chuzan, and Nanzan, vying for supremacy.
Nakijin Castle served as the residence of the Hokuzan King, becoming a base for controlling the northern part of Okinawa Island. The Hokuzan Kingdom prospered economically through trade with China (Ming Dynasty), and its wealth and power are evident from the size of the castle. In particular, for several generations, starting with Haniji, considered the first Hokuzan King, rule was centered around Nakijin Castle.
The Fall of Hokuzan in 1416
The end of the Three Kingdoms period was brought about by the unification of Ryukyu by Sho Hashi of Chuzan. In 1416, Sho Hashi attacked Nakijin Castle and destroyed the last Hokuzan King, Han Anchi. This battle led to the fall of the Hokuzan Kingdom, and Ryukyu moved towards unification.
King Han’anchi was known as a king skilled in martial arts, and Nakijin Castle was considered an impregnable fortress. However, it fell to the skillful strategies of Sho Hashi. This historical event marked a crucial turning point in the formation of the Ryukyu Kingdom.
The Kanshu System during the Ryukyu Kingdom Era
After the fall of Hokuzan, an administrator called a Kanshu (administrator) was dispatched from the Ryukyu Royal Government to Nakijin Castle. The Kanshu acted as the government’s representative, governing the northern region, and this system continued for approximately 250 years until 1665.
During the Kanshu era, Nakijin Castle took on a stronger character as an administrative center rather than a military base, and facilities such as government offices and warehouses were established within the castle. However, with the abolition of the Kanshu system in 1665, Nakijin Castle gradually lost its function and eventually became a ruined castle.
Highlights of Nakijin Castle | Exploring the Castle Grounds
Heiro-mon Gate | The Main Gate to the Castle
A visit to Nakijin Castle ruins begins at the Heiro-mon Gate. This gate is the main entrance to the castle and is characterized by its imposing structure built of Ryukyu limestone. High stone walls rise on both sides of the gate, giving visitors a sense of the castle’s grandeur.
The Heiro-mon Gate was restored in 1962 by the Ryukyu Government, and it preserves its original appearance. Passing through the gate, a stone-paved path leading into the castle grounds appears, giving you the feeling of stepping back in time.
The Beauty of the Old Road and Stone Walls | Landscape Created by Curves
After passing through the Heiro-mon Gate, the old road leading into the castle grounds stretches out before you. This road gently ascends, following the natural terrain, and on both sides, beautiful curved stone walls that characterize Nakijin Castle continue.
The most distinctive feature of Nakijin Castle’s stone walls is that they are not straight lines, but rather form smooth curves. This was due to their construction to conform to the terrain, and also served as a defensive measure. The curved walls made enemy intrusion difficult and also created a visually beautiful landscape.
The height of the stone walls varies depending on the location, but the highest points reach approximately 8 meters. Built using the nozura-zumi technique, where natural stones are stacked as they are, they remain remarkably strong even after more than 600 years.
Ooba (Great Courtyard) | Ceremonial Ground
Climbing the old road leads to a plaza called Ooba. This is the largest space within the castle grounds and is believed to have been the site of ceremonies and political events.
From Ooba, you can enjoy a panoramic view of the East China Sea over the castle walls, and on clear days, you can even see Iheya Island and Izena Island. This scenic viewpoint is a popular spot for many visitors to Nakijin Castle ruins to take photographs.
Main Enclosure (Honmaru) | The Heart of the Hokuzan King
Continuing from the main courtyard, you reach the main enclosure (shukaku), the highest point of the castle. Also known as the “Honmaru,” this is believed to be the site of the Hokuzan King’s residence.
The main enclosure was the most important section of the castle and the political center. While only foundation stones and other remains exist today, it is believed that the king’s residence and government offices once stood here. The view from the main enclosure is magnificent, offering panoramic views of the town below and the surrounding sea.
Shigema Gate Enclosure (Shigemajokaku) | A Sacred Place of Prayer
Located north of Nakijin Castle, the Shigema Gate Enclosure is considered a particularly sacred place within the castle. Here, there is a place of worship called “Tenchijiamachiji,” which is still a place of prayer for locals today.
This is an important area demonstrating that the gusuku (castle) was not merely a military facility, but also a place of prayer. From the Shigeshimamon Enclosure, you can see the cliffs on the north side of the castle and the sea, giving you a real sense of Nakijin Castle’s location as a natural stronghold.
Outer Enclosures and Castle Walls | The Complete Defensive System
Nakijin Castle consists of several outer enclosures (gaikaku) centered around the main enclosure. These enclosures were separated by stone walls, forming a tiered defensive system.
The total length of the castle walls is approximately 1.5 kilometers, making it the second largest after Shuri Castle. The castle walls were skillfully constructed utilizing the varying terrain, making them extremely difficult for attackers to conquer. Walking along the castle walls, you can feel the grandeur and the high level of castle-building technology firsthand.
Nakijin Gusuku Cherry Blossom Festival | A Winter Tradition
Japan’s Earliest Cherry Blossom Spot
Nakijin Castle Ruins are also known as a famous cherry blossom spot. Every year from late January to early February, approximately 660 Taiwanese cherry trees (Prunus campanulata) planted within the castle grounds bloom simultaneously, adorning the stone walls with pink blossoms.
Unlike cherry blossoms on mainland Japan, Okinawan cherry blossoms are characterized by their deep pink color and downward-facing blossoms. The cherry blossoms at Nakijin Castle Ruins are famous as “Japan’s earliest cherry blossom festival,” making it a rare spot to enjoy cherry blossoms in the middle of winter.
The Charm of the Nakijin Castle Cherry Blossom Festival
During the annual Nakijin Castle Cherry Blossom Festival, the castle is illuminated at night. The contrast between the illuminated stone walls and the cherry blossoms is fantastic, allowing visitors to enjoy the castle ruins in a different light than during the day.
The 18th Cherry Blossom Festival in 2025 (Reiwa 7) will be held for nine days, from January 25th (Saturday) to February 2nd (Sunday). The castle is open from 8:00 AM to 9:00 PM (last entry at 8:30 PM), and the castle is illuminated from 6:00 PM to 9:00 PM.
