History and Highlights of Konami Castle (Yonago City, Tottori Prefecture) – A Mountain Castle in Hoki Province Involved in the Genko War
About Konami Castle
Konami Castle (Konami-jo) is a medieval mountain castle located in Konami, Yodoe-cho, Yonago City, Tottori Prefecture. Also known as “Konami Castle,” it is known as a castle in Hoki Province that played an important role during the turbulent Genko period (1331-1334).
For many years, its exact location was not identified, but recent surveys of surrounding burial mounds revealed what appeared to be castle remains, leading to the current location being identified as the site of Konami Castle. Although not particularly high in elevation, its strategic layout, utilizing the surrounding terrain, makes it an indispensable historical site for understanding the history of medieval castles in the San’in region.
History of Konami Castle
The Genko War and the Establishment of Konami Castle
Konami Castle first appears on the historical stage during the turbulent Genko period. In 1331 (Genkō 1), Emperor Go-Daigo was exiled to Oki Island for plotting to overthrow the Kamakura Shogunate. During this period, a warrior named Nawa Nagatoshi was active in Hōki Province.
In 1333 (Genkō 3), when Emperor Go-Daigo escaped from Oki, Nawa Nagatoshi welcomed him to Senjōzan (present-day Kotoura-cho, Tottori Prefecture), which became a base for the anti-shogunate movement. It is believed that Konami Castle functioned as a fortress associated with the Nawa clan during this series of events.
Castle Lords and Changes in the Castle
Regarding the lord of Konami Castle, the name of a warrior named Kiyoshitaka is recorded. Kiyoshitaka was a local lord in Hōki Province and is said to have acted alongside Nawa Nagatoshi during the Genkō War.
After raising an army at Senjōzan, Nawa Nagatoshi and others fought battles against the shogunate forces in various locations. It is presumed that Konami Castle also functioned as an important military base for Emperor Go-Daigo’s forces during this period. However, detailed battle records are not available, and there are no clear records of when the castle ultimately fell or whether it was naturally abandoned.
Late Medieval Period and Beyond
Records concerning Konami Castle become almost nonexistent from the Muromachi period onward. During the Sengoku period, the Amago and Mōri clans vied for power in the San’in region, but there is no evidence that Konami Castle was reused during this time. It is likely that the castle was abandoned relatively soon after the end of the Genkō War and subsequently faded into history.
Structure and Remains of Konami Castle
Location and Layout of the Castle
Konami Castle is located in the vicinity of Shimoharada, Konami, Yodoe-chō, Yonago City, Tottori Prefecture. Built on a hilly area near the Sea of Japan, the castle’s relative elevation (difference in height from the base) is not particularly large, but it occupies a strategic location overlooking the surrounding area.
Regarding the castle’s structure, many details remain unknown due to insufficient archaeological excavation. However, based on the remains confirmed during the excavation of the Kobaharahata site, it is presumed to have possessed the characteristics of a typical medieval mountain castle.
Confirmed Remains
While the remains that can be confirmed today are limited, the following characteristics have been reported:
- Kuruwa (enclosure) remains: Several flat areas have been confirmed, suggesting the presence of a main enclosure and secondary enclosures.
- Earthwork traces: Traces of earthen defensive structures remain in some areas.
- Possibility of a moat: There are areas where the terrain changes, seemingly cutting across the ridge, can be observed.
Given that Kobahara Castle is a mountain castle from the relatively early period of the Genkō era, it is thought to have had a simpler defensive structure than the more complex layouts of later Sengoku period castles.
Relationship with the Kobaharahata Site
The investigation of the Kobaharahata site was the catalyst for identifying the location of Koba Castle. This site is a complex of ruins dating from the Kofun period to the medieval period, and part of the castle site is included within its boundaries. Artifacts such as Haji ware and Sue ware have been unearthed from the site, indicating that this area was a place of human habitation from ancient times.
Highlights and Visitor Guide for Koba Castle

Konami Castle, being one of the relatively early castles, is a valuable resource for regional history research.
Significance of Castle Research
Small, local mountain castles like Konami Castle receive less attention than large castles, but they are important historical sources for understanding the realities of local communities and samurai groups at the time. Carefully investigating and documenting such castle ruins is of great significance to the study of Japanese medieval history.
