This article comprehensively explains everything you need to know before visiting Nakijin Castle Ruins, from its historical background to its highlights, admission fees, opening hours, and access methods.
What is Nakijin Castle Ruins?
Nakijin Castle Ruins, also known as “Hokuzan Castle,” is a historical gusuku located on the Motobu Peninsula in northern Okinawa Island. Built on a hill 90-100 meters above sea level, this castle served as the residence of the King of Hokuzan from the late 13th to the early 15th century.
Protected by a deep 70-80 meter deep gorge to the east and a cliff over 70 meters high behind it, it was a natural fortress renowned as “impregnable.” The castle walls reached approximately 8 meters in height, and fortifications were strategically placed on the surrounding mountains, showcasing the advanced fortification techniques of the time.
History of World Heritage Registration
In November 2000 (Heisei 12), Nakijin Castle Ruins, along with Shuri Castle Ruins, Zakimi Castle Ruins, Katsuren Castle Ruins, Nakagusuku Castle Ruins, Seifa Utaki, Sonohiyan Utaki Stone Gate, Tamaudun Mausoleum, and Shikinaen Garden, were registered as a World Cultural Heritage site as part of the “Gusuku Sites and Related Properties of the Kingdom of Ryukyu.” This marked the international recognition of the importance of the history and culture of the Ryukyu Kingdom.
It is designated as a national historical site and is also selected as the 98th of Japan’s 100 Famous Castles.
The History of Nakijin Castle and the King of Hokuzan
The Hokuzan Kingdom during the Three Kingdoms Period
The 14th century in Ryukyu was a period known as the “Three Kingdoms Period,” in which the kingdom was divided into three powers: Hokuzan, Chuzan, and Nanzan, vying for supremacy. Nakijin Castle served as the residence of the King of Hokuzan during this Three Kingdoms Period, functioning as the political, economic, and cultural center of northern Okinawa Island.
The Hokuzan Kingdom controlled the Yanbaru region in northern Okinawa Island and established its own sphere of influence, including engaging in tributary trade with China (Ming Dynasty). Nakijin Castle played a crucial role as a symbol of its power and as a key castle protecting the northern region.
The Castle’s Construction and Development
Archaeological excavations have revealed that the construction of Nakijin Castle dates back to the late 13th century. In the mid-14th century, the main enclosure (honmaru) was constructed with stone walls, and in the first half of the 15th century, the castle grounds were further expanded.
The Hokuzan Kings ruled for three generations, but in 1416 (Oei 23), the Hokuzan Kingdom was destroyed by Sho Hashi, the King of Chuzan, and Nakijin Castle was captured. This paved the way for the unification of Ryukyu.
Nakijin Castle After the Unification of the Ryukyu Kingdom
After the fall of Hokuzan, a governor (kanshu) dispatched from the Ryukyu royal government was stationed at Nakijin Castle, and it continued to function as a governing center for the northern region. The governor system continued until 1665, after which it was used as a place of religious ceremonies.
Structure and Characteristics of Nakijin Castle Ruins
Castle Layout
Nakijin Castle consists of seven enclosures (kuruwa), including the outer enclosure. The main enclosure (Honmaru) is situated on the summit of a hill 100 meters above sea level, with other enclosures cleverly positioned to protect it, utilizing the natural terrain.
The main enclosures are as follows:
- Main Enclosure (Honmaru): The central part of the castle, believed to have been the living quarters of the King of Hokuzan
- Uchibaru: A sacred space adjacent to the main enclosure
- Ushimi: An enclosure located on the east side of the castle
- Heiromon: An important gate serving as the main entrance to the castle
- Outer Enclosure: A vast defensive line surrounding the entire castle
Beautifully Curved Castle Walls
The most distinctive feature of Nakijin Castle is its beautifully curved castle walls that follow the terrain. The walls, stretching approximately 1.5 kilometers in total, are constructed using a technique called “Nozurazumi,” employing cut limestone blocks.
The castle walls are arranged in a wave-like pattern to conform to the undulating terrain, and their elegant curves are the reason why it is called “one of Okinawa’s finest castles.” The details of the castle walls are extremely beautiful, and they convey to this day the high level of stonemasonry skills of the time.
Heiromon Gate
Heiromon Gate is the main gate of Nakijin Castle and is an important gate that all visitors must pass through to enter the castle. Restored in 1962 (Showa 37), this gate is an arched stone structure that showcases the unique architectural style of the Ryukyu Islands.
High castle walls rise on both sides of the gate, creating a sturdy structure that prevents enemy intrusion. After passing through the gate, a path leads to the castle grounds, allowing visitors to enjoy a stroll while feeling the weight of history.
Highlights of Nakijin Castle Ruins
Spectacular View from the Main Enclosure
The view from the main enclosure (honmaru) is one of the biggest highlights of visiting Nakijin Castle Ruins. From a hilltop approximately 100 meters above sea level, you can enjoy a panoramic view of the cobalt-blue East China Sea stretching endlessly into the distance.
On clear days, you can see Iheya Island, Izena Island, and even Yoron Island, and the breathtaking scenery overwhelms visitors. The view at sunset is particularly spectacular, with the setting sun over the East China Sea and the silhouette of the castle walls creating a fantastical scene.
Shigema-jokaku
Shigema-jokaku is an enclosure located on the north side of the castle, believed to have once been the living quarters of the King of Hokuzan. Although only the remains of the stone walls remain today, it is an important area that allows you to appreciate the scale of the castle at that time.
Uuchibaru
Uuchibaru is a sacred space adjacent to the main enclosure, a place where only women were allowed to enter. During the Ryukyu Kingdom era, important rituals were performed here.
Even today, this area is a sacred site (utaki) and an object of worship, carefully preserved by the local people. This area, imbued with a sacred atmosphere, is a precious place where one can experience the spiritual culture of Ryukyu.
The Ushimi Castle Walls
The castle walls in the Ushimi area of Nakijin Castle feature particularly beautiful curves and are a popular photo spot. The gently undulating walls give the impression of a dragon lying down.
There are also places where you can walk along the top of the walls, allowing you to observe the stonework techniques up close.

Nakijin Castle Ruins are also known as a famous spot for Kanhi-zakura cherry blossoms, the earliest blooming cherry blossoms in Japan. Every year from late January to early February, approximately 660 Kanhi-zakura trees adorn the castle grounds.
