Hase Takayama Castle (Hyogo Prefecture) Complete Guide: History, Remains, and Access Information
Hase Takayama Castle is a medieval mountain castle located in Hase, Santo-cho, Asago City, Hyogo Prefecture. Built on a mountain approximately 460 meters above sea level, this castle served as an important base in the power struggle between the Yamana and Akamatsu clans in Tajima Province, and still conveys the history of the Sengoku period. This article provides a detailed explanation of Hase Takayama Castle’s historical background, castle structure, highlights, and access methods.
Historical Background of Hase Takayama Castle
Construction History and Historical Context
There are various theories regarding the construction period of Hase Takayama Castle, but it is believed to have been built sometime between the Muromachi period and the Sengoku period. Tajima Province has long held an important position as a transportation hub, located on the route connecting Kyoto and the San’in region.
This region was within the sphere of influence of the Yamana clan, a powerful shugo daimyo (provincial governor), but it was also a border area with the Akamatsu clan, who controlled the neighboring Harima Province, and thus served as the front line of the power struggle between the two clans. Given this geopolitical importance, it is presumed that Hase Takayama Castle was built as a defensive stronghold in southern Tajima Province.
The Yamana Clan and Tajima Rule
The Yamana clan was a powerful shugo daimyo during the Muromachi period, known as the “Sixth Lord,” and controlled several provinces, including Tajima. They played a key role as the commander-in-chief of the Western Army during the Ōnin War (1467-1477), but their power declined after the war.
The Yamana clan’s control over Tajima Province was maintained by stationing family members and vassals in various castles. Hase Takayama Castle is thought to have functioned as part of this castle network.
Conflict with the Akamatsu Clan
The Akamatsu clan, the shugo daimyo of Harima Province, sought to expand into southern Tajima Province, leading to frequent clashes with the Yamana clan. Hase Takayama Castle, located near the border between the two opposing forces, was likely a strategically important location and therefore a target of conflict.
During the Sengoku period (Warring States period), internal conflicts arose within the Yamana clan in Tajima Province, intensifying the rivalry among family members. It has been suggested that Hase Takayama Castle may have passed through the hands of multiple forces during this turbulent period.
The Castle’s Demise
While the exact date of Hase Takayama Castle’s abandonment is unclear, given that many medieval mountain castles were abandoned during Toyotomi Hideyoshi’s unification of Japan, it is presumed to have ceased its function sometime between the late 16th and early 17th centuries.
In the Edo period, Tajima Province was divided and governed by multiple domains, with castles and encampments on the plains becoming the political centers. Hase Takayama Castle, as a mountain castle, lost its military role and faded into history.
Layout and Structure of Hase Takayama Castle
Location and Utilization of Topography
Hase Takayama Castle is built on the summit of Mt. Takayama, at an altitude of approximately 460 meters. This mountain rises steeply from the surrounding plains, providing excellent defensive capabilities as a natural stronghold.
The castle is built utilizing the ridge of the mountaintop, and its layout is characterized by its skillful use of the terrain. The steep slopes act as natural barriers, making it difficult for enemies to approach. Furthermore, the mountaintop offers a wide view of the surrounding area, functioning as a military observation post.
Arrangement of the Main Enclosure and Baileys
The central part of Hase Takayama Castle is centered around the main enclosure (honmaru). The main enclosure is located at the highest point of the mountaintop and is thought to have housed the lord’s residence and command post.
Several baileys (kuruwa) are arranged around the main enclosure. These baileys are arranged in a stepped pattern, forming a multi-layered defensive structure. Each enclosure is demarcated by earthworks and steep slopes, designed to prevent enemy incursions in stages.
Moats and Vertical Moats
A notable feature of Hase Takayama Castle’s defensive structures is the presence of moats and vertical moats.
Moats are dry moats dug to cut across ridges, serving to prevent enemy incursions along the ridges. Hase Takayama Castle has moats in front of and behind the main enclosure, enhancing the castle’s defensive capabilities.
Vertical moats are moats dug vertically along slopes, restricting enemy lateral movement and limiting attack routes. Multiple vertical moats have been identified on the slopes of Hase Takayama Castle, representing important remains demonstrating Sengoku period castle construction techniques.
Earthworks and Steep Slopes
Earthworks were built around each enclosure, functioning as defensive walls. The height of the earthworks varies depending on the location, but traces of them can still be seen today.
A “kirigishi” is an artificial cliff created by cutting the edge of a bailey at a near-vertical angle, a defensive structure designed to make it difficult for enemies to climb. At Hase Takayama Castle, clear kirigishi remain in each bailey, demonstrating a typical structure of a medieval mountain castle.
Koguchi (Entrance)
The koguchi, the entrance to the castle, is one of the most important defensive structures. The koguchi at Hase Takayama Castle has a curved structure to prevent enemies from advancing directly, giving the defenders an advantage.
High earthworks are built around the koguchi, allowing for attacks on invading enemies from the flanks. This type of koguchi structure is an important element demonstrating the development of castle-building technology during the Sengoku period.
Highlights of Hase Takayama Castle
Well-Preserved Remains
The greatest appeal of Hase Takayama Castle is the relatively well-preserved remains of this medieval mountain castle. Because it escaped later development, the topography and structure from the time of its construction can still be observed today.
In particular, defensive structures such as moats, vertical trenches, and steep slopes remain clearly visible, making it a valuable historical site where you can experience the castle-building techniques of the Sengoku period.
Stunning Views
From the main enclosure at the summit, you can enjoy a panoramic view of the area around Asago City. On a clear day, you can see a wide expanse of the mountains and plains of Tajima Province, giving you a real sense of the castle’s excellent location as a surveillance base.
Enjoying the different scenery in each season, such as the fresh greenery of spring and the autumn foliage, is another attraction.
The Appeal of Mountain Castle Climbing
Climbing to Hase Takayama Castle can also be enjoyed as mountain castle climbing. While some parts of the trail are well-maintained, there are also steep slopes and rocky areas, providing a moderate amount of exercise.
Experiencing firsthand how difficult it was to attack a medieval mountain castle during the climb is one of the great pleasures of exploring mountain castles. ### Connection to Surrounding Historical Heritage

Hase Takayama Castle and the Mountain Castle Culture of Tajima
Characteristics of Mountain Castles in Tajima
Tajima Province (present-day northern Hyogo Prefecture) was a region where many mountain castles were built from the medieval period to the Sengoku period. Taking advantage of the rugged mountainous terrain, various powers developed mountain castles as defensive strongholds.
Many of Tajima’s mountain castles, though relatively small, possessed strong defensive structures, and the majority were built by local lords and samurai to protect their territories. Hase Takayama Castle can be understood within this context of Tajima’s mountain castle culture.
Comparison with Takeda Castle Ruins
Takeda Castle Ruins, also located in Asago City, became nationally famous as the “Castle in the Sky,” but Hase Takayama Castle retains a more rustic and unspoiled appearance as a mountain castle.
While Takeda Castle ruins incorporate elements of early modern castles, such as stone walls, Hase Takayama Castle retains the typical form of a medieval mountain castle built of earth. Comparing the two allows us to understand the developmental process of castles.
Significance of Mountain Castle Research
Medieval mountain castles like Hase Takayama Castle often have few records in historical documents, making it necessary to uncover their history through archaeological investigations and the creation of castle layout maps.
