Built in the Kusaka district, which spreads out at the foot of Mt. Daisen in the southern part of Yonago City, this castle is an indispensable part of understanding the region’s history. This article comprehensively introduces information that castle fans and history enthusiasts should know, from the historical background of Kusaka Castle to specific highlights and practical information for visitors.
Historical Background of Kusaka Castle
Construction History and Historical Context
Kusaka Castle is a flatland castle built during the Sengoku period and functioned as a base for regional control in Hoki Province (present-day central-western Tottori Prefecture). During this period, the San’in region was the stage for conflict between the two major powers, the Amago clan and the Mori clan, and Kusaka Castle was under their influence.
There are various theories regarding the construction period, but it is believed to have been built sometime between the mid-to-late 16th century by local lords and regional powerful families. The Kusaka area was strategically located at a key transportation hub connecting the Yonago Plain and the foothills of Mount Daisen, making it militarily and economically important.
Castle Lords and Changes
While it is believed that the castle lords of Kusaka Castle were successively powerful local families, detailed records are limited. In the history of Hoki Province, this region was under the influence of the Amago clan and later the Mori clan, and it is possible that Kusaka Castle’s lords changed as a result.
From the late Sengoku period to the early Edo period, Hoki Province was ruled by various clans, including the Kikkawa, Nakamura, and Kato clans, before finally becoming the territory of the Ikeda clan. It is believed that Kusaka Castle ceased to play a military role during this process and was abandoned.
Location and Geographical Characteristics of Kusaka Castle
Geography of the Kusaka District, Yonago City
The Kusaka district of Yonago City, where Kusaka Castle is located, is situated in the southern part of Yonago City, in western Tottori Prefecture. This area is surrounded by a rich natural environment, with Mount Daisen, also known as “Hoki Fuji,” to the east, Yonago city center and the Sea of Japan to the north, and Lake Nakaumi to the west.
Yonago City is located almost in the center of the San’in region and has flourished as a transportation hub since ancient times, serving as the “gateway to San’in.” Within Yonago City, the Kusaka district has played an important role as an entrance to Mount Daisen and as an agricultural area.
Castle Location Conditions
Kusaka Castle was built as a flatland castle, situated on a hill overlooking the surrounding plains. This location possesses typical characteristics of Sengoku period castles, allowing for early detection of enemy movements and utilizing the advantageous terrain for defense.
Located in a position to monitor the transportation route from the foot of Mt. Daisen to the Yonago Plain, it is believed to have functioned not only as a military base but also as a symbol of regional control.
Structure and Layout of Kusaka Castle
Basic Structure of the Castle
Kusaka Castle, a castle of a local powerful family during the Sengoku period, possessed a relatively small but practical structure. Multiple baileys were arranged around the main bailey (honmaru), and a defensive system was constructed that skillfully utilized the natural terrain.
Taking advantage of its location as a hilltop castle, it is presumed that defensive lines were formed using the elevation differences of the slopes. While not as steep as a mountain castle, it had a structure superior in defense to a flatland castle.
Current State of Remains
Currently, no stone walls or buildings remain at the Kusaka Castle site, but the undulations of the terrain and the arrangement of the baileys allow us to imagine the castle’s former appearance. Traces of earthworks and moats, remnants of defensive facilities created by civil engineering works, may remain as part of the terrain.
Current State of Remains
Currently, no stone walls or buildings from the time remain at the Kusaka Castle site, but the former appearance of the castle can be imagined from the topography and the arrangement of the baileys. Investigations by castle researchers and local history enthusiasts are ongoing, gradually revealing the true nature of Kusaka Castle.
