Funakoshi Gusuku (Okinawa Prefecture) Complete Guide: History, Highlights, and Access Explained in Detail
Funakoshi Gusuku, located in Tamagusuku Funakoshi, Nanjo City, Okinawa Prefecture, is an important historical site that conveys the history of the Ryukyu Kingdom era. Believed to have been built in the mid-14th century, this gusuku boasts a unique structure that skillfully utilizes the natural terrain, making it a distinctive presence among the many gusuku scattered throughout Nanjo City.
This article comprehensively explains everything you need to know before visiting Funakoshi Gusuku, from its historical background to its highlights and access methods.
What is Funakoshi Gusuku?
Funakoshi Gusuku is a gusuku site built on a hillside overlooking the Funakoshi settlement in the Tamagusuku district of Nanjo City. Its most distinctive feature is that it was constructed using the upper part of a massive limestone rock. By utilizing the natural bedrock as a foundation, it demonstrates the wisdom of Ryukyu gusuku architecture, minimizing artificial stonework while enhancing defensive capabilities.
Currently, a golf driving range (Short Course Tamagusuku) is located adjacent to the gusuku, and development is progressing in the surrounding area, but the gusuku remains themselves retain the appearance of the time.
What is a Gusuku?
A gusuku (御城) is a term referring to castle ruins unique to the Okinawa region. Unlike the castles of the Sengoku period on the mainland, they did not necessarily serve only as combat facilities, but also as sacred sites (places of worship) or residences of local powerful families called Anji.
Nearly 200 gusuku have been identified on Okinawa Island, and Funakoshi Gusuku is one of them, an important cultural property that tells the history of Nanjo City.
History and Builder of Funakoshi Gusuku
Construction Period and Background
Funakoshi Gusuku is believed to have been built in the mid-14th century. This period is known in Ryukyu history as the “Three Kingdoms period,” a time when three powers—Hokuzan, Chuzan, and Nanzan—divided and ruled Okinawa Island. The Shimajiri region, including Nanjo City, was within the sphere of influence of the Nanzan Kingdom, and local lords (Anji) competed for power by constructing their own gusuku (castles).
Legends of Funakoshi Anji
Several legends remain regarding the builder of Funakoshi Gusuku.
Legend 1: The Theory of the Fourth Son of King Tamagusuku
The most widely known theory is that the fourth son of King Tamagusuku, the fourth king of the Eiso dynasty, built the castle as Funakoshi Anji. The Eiso dynasty ruled Nakayama from the 13th to the 14th centuries, and the legend that a member of the royal family was granted this land and became an Anji suggests the high status of the gusuku.
Legend 2: The Theory of the Eldest Son of Itokazu Anji
Another legend states that the eldest son of the nearby Itokazu Anji became Funakoshi Anji. Itokazu Gusuku is a well-known gusuku (castle) within Nanjo City, and the belief that the family of its lord ruled this area is deeply rooted in the region.
While neither tradition has been confirmed by written documents, the size and location of the gusuku suggest that a powerful lord undoubtedly existed in this area.
Archaeological Findings
Currently, no artifacts have been reported being collected from Funakoshi Gusuku. This is likely due to the possibility of the remains being lost due to later development or natural collapse, or because full-scale excavation has not been conducted. Future investigations may reveal more detailed information about the construction period and actual use of the castle.
Structure and Characteristics of Funakoshi Gusuku
Location and Topographical Utilization
Funakoshi Gusuku is built in a strategically advantageous location: on a hill east of the Funakoshi settlement. This location offered the following advantages:
- Excellent Visibility: The entire Funakoshi settlement could be overlooked from the hillside, allowing for early detection of approaching enemies.
- Natural Defense: The slope itself served as a defensive wall.
- Access to Water Sources: Its proximity to the settlement made securing water for daily life easy.
Architectural Techniques Utilizing Limestone
The most distinctive feature of Funakoshi Gusuku is the use of massive natural limestone blocks as part of the castle walls. The southern part of Okinawa Island is rich in Ryukyu limestone, and architectural techniques that maximized this geological feature were employed.
Artificially constructed stone wall sections have also been confirmed, resulting in a hybrid structure combining natural bedrock and artificial stonework. Such architectural techniques demonstrate the practical wisdom of the local lords of the time, allowing for the construction of a robust defensive structure while conserving labor.
Existing Remains
Currently identifiable remains include:
- Limestone Foundation: Natural bedrock that formed the foundation of the gusuku (castle)
- Traces of Stonework: Remains that partially demonstrate the stonework techniques of the time
- Flat Area: A flat area presumed to have been used as the residence of the Anji (local lord) or a place for rituals
These remain, but detailed layout plans and reconstruction drawings are not currently publicly available.

Gusuku Culture and the History of the Ryukyu Kingdom
To understand Funakoshi Gusuku more deeply, it is important to know the overall Gusuku culture and the historical background of the Ryukyu Kingdom.
Gusuku Period (12th-15th Centuries)
From around the 12th century, local powerful families called Anji rose to prominence throughout Okinawa, each building Gusuku and competing for power. This period is called the “Gusuku Era.” Funakoshi Gusuku is one of the castles built during this time.
The Three Kingdoms Period (14th-Early 15th Century)
In the 14th century, Okinawa Island was divided and ruled by three powers: Hokuzan, Chuzan, and Nanzan, marking the “Three Kingdoms Period.” The mid-14th century, when Funakoshi Gusuku was built, coincides with the period when these three kingdoms were in balance.
Unification of the Ryukyu Kingdom (1429)
In 1429, Sho Hashi of Chuzan unified the three kingdoms, establishing the Ryukyu Kingdom. After unification, many of the local lords were gathered in Shuri, and the regional gusuku gradually fell into disuse. It is believed that Funakoshi Gusuku was also abandoned during this process.
Diverse Functions of Gusuku Castles
Gusuku castles were not merely military facilities, but possessed a variety of functions, including:
- Political Center: A base of governance as the residence of the Anji (local lord)
- Religious Facility: A sacred site serving as a place of worship (uganju)
- Economic Center: A place for storing trade goods and holding markets
- Community Core: A spiritual center for local residents
It is presumed that Funakoshi Gusuku also possessed a combination of these functions.
Preservation of Funakoshi Gusuku and Future Challenges
Current State of Preservation
Funakoshi Gusuku is recognized as a historical site of Nanjo City, but it is not designated as a national or prefectural cultural property. Therefore, organized preservation and maintenance efforts are limited, and some of the remains may be affected by natural collapse and surrounding development.
The Need for Future Investigation and Preservation
To properly evaluate the historical value of Funakoshi Gusuku and pass it on to future generations:
- Full-scale archaeological investigation: Identifying the construction period through artifact collection and detailed surveying of the remains.
- Literature research: Verification of legends concerning Funakoshi Anji.
- Formulation of a preservation plan: A plan to prevent the collapse of the remains and preserve them appropriately.
- Improvement of the viewing environment: Installation of safe walking paths and explanatory signs.
If these efforts are made, Funakoshi Gusuku can be further utilized as an important tourism and educational resource for Nanjo City.
