Haga Castle (Hyogo Prefecture) Complete Guide: A Thorough Explanation of History, Highlights, and Access
Located in Haga-cho, Shiso City, Hyogo Prefecture, Haga Castle is a medieval mountain castle built in the mountainous region of Harima. Situated on the summit of Shiroyama Mountain at an altitude of 456 meters, this castle played a crucial role from the Heian period to the Sengoku period as a strategic point overlooking the important Inaba Road. Currently, it is maintained as Haga Castle Historical Park, and the restored two-story turret and gatehouse evoke its former glory, making it a popular tourist spot.
History of Haga Castle: From the Heian Period to the Sengoku Period
Construction by Haga Shichiro and Early History
The history of Haga Castle dates back to the Heian period. It is believed that Haga Shichiro, a local powerful family who ruled this area, built the castle on the summit of Shiroyama Mountain to monitor the Inaba Road and control the region. The Haga clan, whose name is the origin of the place name Haga, held considerable power in the mountainous region of Harima Province.
The castle was built in an excellent location overlooking three major roads: the Inaba Road connecting Himeji and Tottori, and the road leading to Chikusa. This location was not only strategically important for military surveillance but also economically significant as a transportation hub.
The Nakamura Clan’s Era: Western Migration from Musashi Province
With the arrival of the Kamakura period, Haga Castle underwent a major transformation. The Nakamura clan, who had migrated west from Chichibu District in Musashi Province (present-day Saitama Prefecture), entered the area as retainers of the Kamakura Shogunate and made Haga Castle their residence. The Nakamura clan was a family that had traveled all the way from the Kanto region to the mountainous region of Harima, and it is believed that they were tasked with governing the area by order of the Shogunate.
The Nakamura clan’s rule continued until the end of the Sengoku period. During the Sengoku period, Harima Province was a region where powerful daimyo such as the Akamatsu and Bessho clans held sway. However, the Nakamura clan, based at Haga Castle, remained a small lord in the mountainous area, protecting the land while sometimes being subservient to larger forces.
The End of the Sengoku Period and the Abandonment of the Castle
Towards the end of the Sengoku period, as Hashiba Hideyoshi (later Toyotomi Hideyoshi) pacified Harima, Haga Castle was also affected. During the Tensho era (1573-1592), it is believed that Haga Castle disappeared from the historical stage during Hideyoshi’s campaign to conquer various castles in Harima. In the Edo period, due to policies such as the “One Castle Per Province” decree, Haga Castle was completely abandoned.
Structure and Characteristics of Haga Castle
Location and Layout as a Mountain Castle
Haga Castle is a typical mountain castle built on the summit of Shiroyama, an isolated peak with an elevation of 456 meters. Unlike castles on flat land, mountain castles are defensive structures that make maximum use of the natural terrain, and Haga Castle strongly exhibits this characteristic.
The castle’s layout unfolds around the mountaintop, with multiple baileys (kuruwa) arranged around the main enclosure (honmaru). The steep slopes acted as natural barriers, making enemy intrusion difficult. Even today, traces of the original defensive structures can be seen along the walking trails.
Features of the Stone Walls and Remains
The stone walls are a notable feature of Haga Castle’s remains. Relatively solid stonework remains for a medieval mountain castle, providing valuable information about the castle-building techniques of the time. These stone walls were constructed using a technique called “nozurazumi,” characterized by a simple yet robust construction using natural stones piled up as they were.
At the site of the main enclosure on the mountaintop, the arrangement of stones believed to be building foundations can be seen, suggesting the presence of watchtowers and residences here in the past. Furthermore, the layout of the baileys and the traces of the cliffs indicate that this castle was not merely a fort, but possessed the functionality to withstand a siege for a certain period of time.
Relationship with the Inaba Road
The most distinctive feature of Haga Castle is its location overlooking the important Inaba Road. The Inaba Road was a major transportation route connecting the Sanyo Road and the Sea of Japan side, and was extremely important for the distribution of goods and information, as well as military movements.
From the castle hill, it was possible to observe the movements of people traveling along this road, effectively functioning as a “road watchtower.” Additionally, the road leading to the Chigusa area was also visible, making it an ideal location for early detection of approaching enemies from multiple directions.
Highlights of Haga Castle Historical Park
Restoration through the Hometown Revitalization Project
The current Haga Castle Historical Park was developed using the “100 Million Yen Hometown Revitalization Project” implemented by the Takeshita Cabinet in 1989 (Heisei 1). This project provided 100 million yen to local governments nationwide to be used for regional revitalization. Haga Town (at the time) used these funds to restore Haga Castle and develop the park.
Through this restoration project, the historical mountain castle was revived in the modern era and reborn as a valuable tourist resource for the region. Excavation surveys and document research were conducted during the development, aiming for a restoration that was as historically accurate as possible.
Restored Two-Story Turret (Haga Castle Learning Museum)
The central facility of Haga Castle Historical Park is the two-story turret, which has been reconstructed in wood. This turret is not merely a reconstructed building; its interior is open to the public as the “Haga Castle Learning Museum,” where visitors can learn about the history of Haga Castle and medieval mountain castles. The museum displays historical materials related to Haga Castle, artifacts unearthed during archaeological excavations, and replicas of medieval weapons and everyday items. It also functions as an observation space, offering stunning views of the Harima Mountains on clear days.
The turret’s architectural style replicates the simple yet practical construction seen in medieval mountain castles, allowing visitors to experience the atmosphere of castle architecture from that period. The warmth unique to wooden construction and the sturdy, no-nonsense appearance characteristic of mountain castles are particularly impressive.
Kabukimon Gate and Castle Facilities
Restored alongside the two-story turret is the Kabukimon gate. The Kabukimon gate is a common gate style used in medieval castles, characterized by its simple structure of a horizontal beam resting on two pillars. Haga Castle’s Kabukimon gate has been restored as the formal entrance to the castle, inviting visitors into the world of the Middle Ages.
Passing through this gate, you’ll find yourself in the former castle grounds, where you can experience the layout of the main keep and baileys firsthand. Well-maintained walking paths allow for safe exploration of various parts of the castle, making it possible to observe the remains of stone walls and earthworks up close.
Nighttime Illumination and a Fantastical Landscape
One of the most noteworthy attractions of Haga Castle Historical Park is its nighttime illumination. After sunset, the reconstructed two-story turret is lit up, creating a fantastical scene that stands out against the dark night sky—a truly picturesque sight.
The illuminated turret presents a completely different appearance from its daytime counterpart, exuding the mystical atmosphere of a medieval mountain castle. The illumination is particularly stunning in the crisp autumn and winter air, making it a popular spot for many photography enthusiasts and tourists.
Looking at the illuminated castle in the tranquil mountain setting, one can almost picture the samurai who once defended this land. This fantastical landscape is an experience unique to Haga Castle Historical Park.
The Magnificent View
The view from Haga Castle, located on a mountaintop 456 meters above sea level, is a major attraction that captivates visitors. If the weather is good, you can enjoy a magnificent panorama of the Harima Mountains.
In particular, the view of the settlements along the Inaba Road and the center of Haga Town spread out below is breathtaking. It’s impossible not to feel a sense of historical romance when you imagine that the former lords of the castle also gazed upon this same view while watching over their territory.
You can also enjoy the beauty of nature throughout the seasons, from the fresh greenery of spring to the vibrant autumn leaves. Especially during the autumn foliage season, the mountains are painted in shades of red and yellow, creating a magnificent landscape.
