History of Terauchi Castle | Castles in Hoki Province during the Sengoku Period
The Position of Terauchi Castle in Hoki Province
Hoki Province during the Sengoku period, when Terauchi Castle was built, was a turbulent region where powerful daimyo such as the Amago, Mori, and Kikkawa clans vied for supremacy. The area around Yonago was a strategic transportation hub facing Lake Nakaumi, and as a militarily and economically important region, many castles were built there.
As its name suggests, Terauchi Castle was built adjacent to a temple (Zuizenji Temple), and it has been suggested that it may have served a defensive function for the so-called “temple town.” In the medieval period, temples were not merely religious institutions, but also functioned as centers of local politics, economy, and military power. Terauchi Castle is thought to have played an important role in regional control as a military base for these temple forces.
Construction Period and Lord
Regarding the exact construction period and lord of Terauchi Castle, there are few clear historical records, and many details remain unknown. However, based on the castle’s form and location, it is estimated to have been built during the mid-to-late Sengoku period (Warring States period).
In the Yonago region, the Yamana, Amago, and Mori clans vied for power during the Sengoku period. Particularly in the latter half of the 16th century, Kikkawa Motoharu, in the process of consolidating his control over Hoki Province, constructed many castles around Yonago. Terauchi Castle may have also been built or renovated during this period by powerful local lords or temple forces.
Relationship with Yonago Castle
Terauchi Castle and Yonago Castle are different castles in terms of both era and function. Yonago Castle was fully developed as a modern castle by Nakamura Kazutada in 1601, while Terauchi Castle, an older medieval mountain castle, served a different role.
Before Yonago Castle was built, several medieval castles were scattered around Yonago, and Terauchi Castle was one of them. It is believed that with the construction of Yonago Castle, these medieval castles gradually ceased to function and were abandoned. However, the remains of Terauchi Castle still exist today, making them valuable for understanding the castle history of the Yonago region before Yonago Castle.
Terauchi Castle’s Layout and Remains | Castle Structure Observable on Site
Basic Structure of the Castle
Terauchi Castle was built as a hill castle, and its layout is characterized by its skillful use of the natural terrain. The main enclosure is situated on a hill approximately 25 meters above sea level, with multiple enclosures surrounding it. While the relative elevation difference is relatively small at about 18 meters, its location overlooking the surrounding plains suggests it functioned as a base for surveillance and defense.
Arrangement of Enclosures
The most distinctive feature of Terauchi Castle is the clearly surviving shape of its enclosures. Multiple enclosures are arranged in a stepped fashion around the main enclosure, exhibiting a typical structure for a medieval mountain castle. The flat surfaces of each enclosure are relatively well-preserved, allowing visitors to appreciate the scale of the castle at the time.
The main enclosure is located at the highest point of the castle, offering panoramic views of the surrounding area. Parts of it are integrated with the grounds of Zuizenji Temple, indicating a close relationship between the temple and the castle.
Earthworks and Moats
At Terauchi Castle, traces of earthworks can be seen around the enclosures. Earthworks are earthen walls designed to prevent enemy intrusion and are a basic defensive structure of medieval mountain castles. Furthermore, it has been suggested that a moat may have been constructed to cut across the ridge, which is thought to have enhanced the castle’s defensive capabilities.
Relationship with Zuizenji Temple
Currently, part of the Terauchi Castle ruins is within the grounds of Zuizenji Temple. The integrated structure of the temple and castle is characteristic of medieval “temple towns” and “temple castles.” When visiting the grounds of Zuizenji Temple, being mindful of the castle remains will allow for a deeper understanding of the landscape at that time.

The Position of Terauchi Castle in Yonago City’s Castle History
Transition Period from Medieval to Early Modern Period
The castle history of Yonago City is a good example of the transition from medieval mountain castles to early modern flatland castles. Medieval mountain castles like Terauchi Castle functioned as bases for regional control during the Sengoku period, but with the arrival of the Edo period, that role shifted to the larger early modern castle, Yonago Castle.
Castle Network of Hoki Province
During the Sengoku period, numerous castles were built in Hoki Province, forming a interconnected castle network. Terauchi Castle is thought to have contributed to regional defense and control as part of this network. Several medieval castles have been identified in the Yonago area alone, and Terauchi Castle occupies an important position among them.
Temple Power and Castles
A key characteristic of Terauchi Castle is its close connection to a temple (Zuizenji Temple). In the medieval period, temples possessed not only religious authority but also economic and military power. Terauchi Castle was likely built as a military base for such temple power, and it is noteworthy as an example demonstrating the multifaceted role of temples in medieval society.
