Builder and Construction Date
The builder is said to be Yuki Sukehiro, and the construction date is said to be Kencho 2 (1250). Sukehiro was the grandson of Yuki Tomomitsu, who distinguished himself in Minamoto no Yoritomo’s conquest of Oshu, and he moved to Shirakawa District and adopted the name Shirakawa.
History of Shirakawa Castle
Minamoto no Yoritomo’s Conquest of Oshu and Yuki Tomomitsu
The history of Shirakawa Castle dates back to Minamoto no Yoritomo’s conquest of Oshu in 1189. Yuki Tomomitsu, who distinguished himself in this battle, was rewarded with the position of jitō (land steward) of Shirakawa Manor. Tomomitsu was a powerful samurai based in Yuki, Shimotsuke Province, and at this point, he did not directly descend to Shirakawa.
Construction of the Castle by Yuki Sukehira and the Establishment of the Shirakawa Yuki Clan
In 1250, Yuki Sukehira, Tomomitsu’s grandson, descended to Shirakawa County and built Shirakawa Castle on Mount Fujisawa. Sukehira adopted the name Shirakawa in this area, marking the beginning of the history of the Shirakawa Yuki clan. Sukehira developed Shirakawa Castle as a base for governing the Shirakawa region, and thereafter, this castle became the residence of successive generations of the Shirakawa Yuki clan.
Prosperity during the Reign of Munehiro and Chikatomo
Yuki Munehiro, the son of Sukehiro, was an outstanding figure of exceptional military prowess, greatly expanding the Shirakawa clan’s territory. Munehiro and his son Chikatomo were appointed to the Mutsu Provincial Government Council during the Shoo era (1288-1293), solidifying the Shirakawa Yuki clan’s position in the Tohoku region.
During this period, the Shirakawa Yuki clan expanded their influence in the surrounding areas from their base at Shirakawa Castle, reaching the height of their prosperity as a powerful samurai family in southern Mutsu Province. It is believed that the castle’s fortifications were gradually expanded and improved, strengthening its defensive capabilities.
Turmoil during the Nanboku-cho Period
With the onset of the Nanboku-cho period, the Shirakawa Yuki clan also became embroiled in turmoil. While the Shirakawa Yuki clan generally sided with the Northern Court, they sometimes participated in battles against the Southern Court amidst the complex political situation in the Tohoku region. During this period, Shirakawa Castle’s importance as a military base increased, and it is presumed that practical defensive facilities were constructed.
From the Muromachi Period to the Sengoku Period
Throughout the Muromachi period, the Shirakawa Yuki clan maintained their power with Shirakawa Castle as their base. However, with the advent of the Sengoku period, the rise of powerful surrounding daimyo gradually worsened the Shirakawa Yuki clan’s position.
Especially in the 16th century, caught between powerful daimyo such as the Satake clan invading from the south and the Date clan from the north, the Shirakawa Yuki clan’s power steadily declined.
The Decline of the Shirakawa Yuki Clan and the Abandonment of the Castle
At the end of the Sengoku period, the Shirakawa Yuki clan lost power in conflicts with surrounding daimyo and ultimately perished. Along with the decline of the Shirakawa Yuki clan, Shirakawa Castle also ceased to serve its purpose and became an abandoned castle. While there are various theories regarding the exact date of its abandonment, it is generally believed to have occurred sometime between the late 16th and end of the 16th century.
Afterward, the Shirakawa area was ruled by various clans, including the Satake and Gamo clans. During the Edo period, Shirakawa Komine Castle (Shirakawa Castle) was developed as a new base, and Shirakawa Castle disappeared from the historical stage.
Remains and Highlights of Shirakawa Castle
Details of Existing Remains
At the Shirakawa Castle site, valuable remains exhibiting the characteristics of a medieval mountain castle have been confirmed in good condition.
Enclosures (Kuruwa)
The central part of the castle consists of multiple enclosures centered around the main enclosure. In particular, several layers of enclosures called obi-kuruwa (belt-shaped enclosures), created by leveling the slope in a belt-like fashion, have been confirmed, demonstrating a typical layout of a medieval mountain castle. These enclosures are thought to have served both defensive and residential functions.
Earthworks (Dorui)
Earthworks surround the enclosures as defensive structures. The earthen ramparts, built by piling up earth, served to prevent enemy intrusion and also to shield the interior of the enclosure from outside view. The clearly visible ramparts today are important remains for understanding the castle construction techniques of the time.
Dry Moats
To strengthen the castle’s defenses, multiple dry moats were excavated. Dry moats, which do not hold water, are a typical defensive structure in mountain castles and served to hinder enemy advances. The dry moats at Shirakawa Castle are cleverly positioned, utilizing the terrain, demonstrating the high level of castle construction technology in the medieval period.
Moats
Moats dug to divide the ridge have also been identified. Moats are important defensive structures in mountain castles to prevent enemy intrusion along the ridge, and they are strategically placed at Shirakawa Castle.
Preservation of Remains
Since the Shirakawa Castle site was preserved as a forest without undergoing large-scale development after its abandonment, the remains are relatively well-preserved. Earthworks, dry moats, and the elevation differences of the baileys remain clearly visible, making this a valuable historical site where the layout of a medieval mountain castle can be confirmed firsthand.
Characteristics as a Castle
Shirakawa Castle is a typical medieval mountain castle built on a hill overlooking the Abukuma River. Its layout, which skillfully utilizes the natural terrain, is an important example showing the evolution of castle construction techniques from the Kamakura period to the Sengoku period.
In particular, the structure with multiple terraced baileys demonstrates the wisdom of medieval mountain castles in efficiently utilizing the limited mountaintop area, making it a group of remains of high value for castle research.
Investigation and Research
History of Excavation
At the Shirakawa Castle site, detailed investigations were conducted by the Shirakawa City Board of Education in preparation for designation as a national historical site.
