History of Kushikino Castle
Kamakura Period: Construction and Governance by the Kushikino Clan
The history of Kushikino Castle dates back to the Kamakura period. It is believed that Kushikino Castle was built during the Kenkyu era (1190-1198) by Kushikino Saburo Tadamichi. The Kushikino clan, as local lords of Satsuma Province, developed Kushikino Castle as their base of operations.
With Kushikino Tadamichi as the first lord, the Kushikino clan resided in this castle for generations. The second lord, Tadatoshi, the third, Tadakiyo, and the fourth, Tadaaki, continued to rule, and the Kushikino clan maintained their power as a powerful local family.
Nanboku-cho Period: Conflicts with the Shimazu Clan and Changes in Rule
The fate of the Kushikino clan changed dramatically during the Nanboku-cho period. During the time of the fifth lord, Kushikino Tadaaki, in 1342 (Kōkoku 3), the Kushikino clan was defeated in battle against Shimazu Sadahisa, and came under the control of the Shimazu clan. As a result of this battle, Kushikino Castle became a fortress under the control of the Shimazu clan, and thereafter, Shimazu vassals governed the area as jitō (land stewards).
From this period onward, Kushikino Castle began to function as one of the Shimazu clan’s important bases in Satsuma Province. After coming under Shimazu control, Shimazu vassals such as the Kawakami and Yamada clans served as jitō (land stewards).
Sengoku Period: Shimazu Iehisa and the Formation of Kushikino Foothills
In the late Sengoku period, Kushikino Castle became deeply connected to Shimazu Iehisa, the youngest of the four Shimazu brothers. In 1570, Shimazu Iehisa was granted the position of jitō of Kushikino by his father, Shimazu Takahisa, and at the age of 23, he moved to the area and made Kushikino Castle his residence.
Shimazu Iehisa was born at Isaku Castle and was a skilled warrior who received instruction from his grandfather, Shimazu Tadayoshi (Nisshin-kō). Using Kushikino Castle as his base, Iehisa contributed to the expansion of the Shimazu clan’s power. In the same year, Iehisa’s eldest son, Shimazu Toyohisa, was born at Kushikino Castle.
Shimazu Toyohisa is known as a renowned general who later met a heroic end protecting Shimazu Yoshihiro at the Battle of Sekigahara, and Kushikino Castle is valuable as a castle associated with an important warlord in the history of the Sengoku period.
During this period, a samurai settlement called “Kushikino Fumoto” was formed around Kushikino Castle. Due to the Satsuma Domain’s unique system of outer castles, samurai resided around Kushikino Castle, establishing a system to defend and govern the region.
Development as a Town at the Foot of the Mountain (Edo Period and Beyond)
In the Edo period, Kushikino Castle’s role as a military base diminished, but Kushikino Fumoto continued to occupy an important position as one of the Satsuma Domain’s outer castles. Parts of the castle grounds were used as shrines and temples, and the landscape of samurai residences lined the foot of the mountain.
After the Meiji Restoration, the remains of Kushikino Castle were gradually lost, but important structures such as deep dry moats, earthworks, and baileys still remain, conveying the appearance of a castle from the medieval to Sengoku period.
Structure and Layout of Kushikino Castle
Characteristics of a Group-Bailey Mountain Castle
Kushikino Castle is a group-bailey mountain castle divided by deep dry moats. It was constructed on a hill of Shirasu plateau through civil engineering, with multiple baileys (flat areas) arranged within. Six large baileys were built in the center of the castle, each separated by a deep dry moat, effectively preventing enemy intrusion.
The Shirasu plateau, unique to the Satsuma region, is relatively easy to excavate and allows for the formation of nearly vertical cliffs, making it possible to construct a castle suitable for defense. Kushikino Castle’s structure makes the most of this characteristic.
Main Enclosures and Layout
The castle grounds of Kushikino Castle stretched long from north to south. While the southern end has been partially lost due to modern housing development, the central remains are well-preserved.
The castle’s center is the area where the current Minamikata Shrine is located and the area to its west. Minamikata Shrine itself was built using one of the castle’s enclosures, occupying an important position as part of the castle’s remains. Multiple enclosures were arranged around this main enclosure.
On the east side, the remains of a moat are clearly visible, indicating its function as a defensive line demarcating the castle grounds. Furthermore, earthen ramparts surrounded each enclosure, demonstrating a strategy to further enhance defensive capabilities.
Remains of Dry Moats and Earthen Rampantworks
One of the greatest highlights of Kushikino Castle is its deeply excavated dry moats. Taking advantage of the characteristics of the Shirasu plateau, the dry moats, with their nearly vertical cliffs, were powerful defensive structures that physically prevented enemy intrusion.
Even today, remnants of dry moats can be seen in various locations within the castle grounds. The horizontal moats separating the baileys, in particular, are large in scale, demonstrating the advanced civil engineering techniques of the time. The depth of the dry moats varies depending on the location, but in some places they reach several meters, illustrating the high level of defense in its heyday.
Earthworks also remain in various parts of the castle. The earthworks built along the edges of the baileys were important structures for protecting against enemy arrows and firearms. Some stone walls have also been identified, showing traces of later modifications.
Moats and Defensive Lines
The moats remaining on the east side of the castle were structures designed to cut off the ridge and prevent enemy incursions. The moats at Kushikino Castle are relatively well-preserved, making them important remains for understanding the castle’s defensive structure.
Moats not only simply cut through the terrain, but also formed multiple defensive lines by placing earthworks and baileys before and after them. This complex defensive structure is a valuable example of the development of castle construction technology during the Sengoku period.
Highlights of Kushikino Castle
Minamikata Shrine and Castle Remains
Minamikata Shrine is the central point of interest when visiting Kushikino Castle. This shrine was built using one of the castle’s baileys, and the shrine grounds themselves are part of the castle’s remains.
Remnants of earthworks and dry moats remain around Minamikata Shrine, indicating that the area west of the shrine was the castle’s central area. Walking along the approach to the shrine and observing the layout of the baileys and the topography allows you to experience the structure of a medieval mountain castle.
From the area around the shrine, you can overlook the town of Kushikino, giving you a real sense of the castle’s strategic importance in monitoring and controlling the surrounding area.
Deep Dry Moats
The greatest attraction of Kushikino Castle is the deep dry moats that still remain today. The dry moats separating the baileys are particularly large in scale, and the nearly vertical cliffs characteristic of the Shirasu plateau are impressive.
Walking along the bottom of the dry moat, one is overwhelmed by its depth and width. Imagining the sieges of the time, one can understand how difficult it must have been to cross this moat and enter the castle. Observing the shape and arrangement of the dry moat allows one to learn about the ingenuity of medieval castle construction techniques.
Traces of Earthworks and Stone Walls
Earthworks remaining throughout the castle grounds were built around the edges of the baileys. Their height varies depending on the location, but in well-preserved areas, a height of 1-2 meters can be observed.
In some areas, traces of stone walls can also be seen, which are thought to be the result of renovations from the Sengoku period to the early Edo period. While castles in the Satsuma region were primarily constructed of earth, stone was sometimes used in important areas, and Kushikino Castle is one such example.
Place Name “Shironomoto” and Historical Landscape
The place name “Shironomoto” still remains in the central part of Kushikino Castle, indicating that this area was near the castle’s main keep. Place names are important clues that convey the memory of history, and in the case of Kushikino Castle, they are a valuable source of information for understanding the location of the castle’s center.
Walking around the area, you can find fragments of the Edo period appearance of Kushikino Fumoto, such as old stone walls, well remains, and remnants of samurai residences.
