Complete Guide to Shukuno Castle (Komono-cho, Mie-gun, Mie Prefecture) | History, Remains, and Access Explained in Detail
What is Shukuno Castle?
Shukuno Castle is a medieval hilltop castle located in Shukuno, Komono-cho, Mie-gun, Mie Prefecture. Utilizing the Kinkei River as a natural moat, it was built on the ridge of a protruding small hill. As a Sengoku period castle, remnants such as earthworks and trenches remain well-preserved today.
Komono-cho is located at the eastern foot of the Suzuka Mountains and is a tourist destination known for Yunoyama Onsen and Mount Gozaisho. However, in addition to Shukuno Castle, this region also contains other castles associated with the Hijikata clan, such as Komono Castle and Rikio Castle, forming an important group of historical sites for understanding the realities of feudal rule in northern Ise during the medieval period.
Castle Location and Topographical Features
Shukuno Castle was built on an isolated hill on a river terrace formed by the Kinkei River. This hill stretches long and narrow from east to west, protected by steep slopes to the north and south. The southern side, in particular, faces the Kinkei River and features a sheer cliff face, making the most of the natural fortifications.
The castle grounds consist of two main enclosures: the main keep (honmaru) and the northern enclosure. The southern end is clearly separated from the ridge by a moat. This moat, approximately 3 meters deep and 5 meters wide, served as an important defensive structure to prevent enemy intrusion.
History of Shukuno Castle
Construction Period and Builder
There are no reliable historical records regarding the construction period or builder of Shukuno Castle, so the details remain unknown. However, based on the castle’s structure, layout, and surrounding historical background, it is estimated to have been built during the Sengoku period (late 15th to 16th centuries).
The Komono region was within the sphere of influence of the Hijikata clan during the medieval period, and it is highly likely that Shukuno Castle was built by the Hijikata clan, their relatives, or their retainers. The Hijikata clan, as powerful local lords in northern Ise, solidified their control by building multiple castles in the region.
The Hijikata Clan and the Castle Network of the Komono Region
Besides Shukuno Castle, several other castles exist around Komono Town, including Komono Castle (the main castle) and Rikio Castle. These are believed to have formed a castle network supporting the Hijikata clan’s rule.
Komono Castle is thought to have functioned as the Hijikata clan’s base, while Shukuno Castle and Rikio Castle served as branch castles, playing roles in territorial control and military bases. Shukuno Castle, in particular, was strategically important, positioned to monitor and control the transportation routes along the Kinkei River.
Transition from the Sengoku Period to the Early Modern Period
At the end of the Sengoku period, Oda Nobunaga’s invasion of northern Ise drastically altered the power dynamics of the region. The Hijikata clan also came under the influence of the Oda clan, and eventually, after the era of Toyotomi Hideyoshi, the Komono Domain was established during the Edo period. It is believed that Shukuno Castle was abandoned during this process, but there are no records of the exact date of its abandonment. It is likely that it lost its function as a military facility around the time of the “One Castle Per Province” decree (1615) in the early Edo period.
Castle Grounds and Residence Site
Currently, the area east of Genchoji Temple and south of Inari Shrine is called “Shiroyashiki” (Castle Grounds), and is considered to be the site of the former residence. While the mountaintop castle served as a military fortification, this castle grounds is thought to have served as a living space and administrative office during peacetime.
This structure, combining a mountain castle with a residence at the foot of the mountain, is a common form of castle construction in the Sengoku period, and it is clear that Shukuno Castle followed this typical pattern.
Layout and Remains of Shukuno Castle
Structure of the Main Enclosure (Honmaru)
The main enclosure is the central part of Shukuno Castle and is built at the highest elevation. It measures approximately 30 meters east-west and 20 meters north-south, and is surrounded by earthen ramparts. This earthen embankment, approximately 1.5 meters high, still exists, conveying the appearance of the defensive facilities at the time.
To the south of the main enclosure, an earthen mound believed to be a watchtower base can be seen, suggesting the possibility of a watchtower or turret being built here. Furthermore, the interior of the main enclosure is relatively flat, and traces of buildings can be inferred from the topography.
The North Enclosure and its Function
The north enclosure is a fortified area located north of the main enclosure, at a slightly lower elevation. Its size is roughly the same as the main enclosure, and traces of earthen embankments remain around it as well.
The north enclosure is thought to have functioned as a forward position defending the main enclosure, positioned to prepare for enemy invasions from the north. It may also have played a rear-support role, such as stationing soldiers or storing supplies.
Details of the Moat
A clear moat remains at the southern end of the castle grounds. This moat was excavated in a way that completely cuts across the ridge, and has a V-shaped cross-section. The moat is approximately 3 meters deep and 5 meters wide, and is still clearly visible as a geographical feature.
Earthworks are built on both sides of the moat, demonstrating a design intended to further enhance its defensive capabilities. This moat clearly separates the castle grounds from the outside, physically preventing enemy intrusion.
Earthworks Arrangement and Characteristics
The earthworks of Shukuno Castle surround the main enclosure and the northern enclosure. The earthworks on the east and south sides of the main enclosure are particularly well-preserved, with some sections remaining 1-2 meters high.
Observing the structure of the earthworks reveals a combination of sections excavated from the natural ground and sections constructed by earthworks. This demonstrates the level of civil engineering technology at the time, showing ingenuity in efficiently constructing defensive facilities with limited labor.
Entrance to the Castle and Circulation within the Castle
The current entrance to the castle is located on the northwest side of the castle grounds. From here, a mountain path leads to the northern enclosure, and further on, to the main enclosure.
This route may follow the original main entrance (Ote-michi) route. However, medieval castles typically had multiple access routes, and it’s possible that other routes, such as a rear entrance (Karamete-michi), which are not currently visible, also existed.
Preservation of the Remains
The remains of Shukuno Castle are relatively well-preserved, having escaped development. The moats and earthworks, in particular, remain clearly visible, providing valuable information for understanding the castle’s structure in its heyday.
However, in some areas, the remains are unclear due to overgrown trees and soil accumulation. With proper preservation and management in the future, more information can be passed on to future generations.
