History and Background of Yuki Castle
Late Heian Period to Kamakura Period: Castle Construction
The history of Yuki Castle dates back to the late Heian period. In 1171 (Shoan 1), Asamitsu, the fourth son of Oyama Shimotsuke Daijo Masamitsu, who distinguished himself in the pursuit of the Taira clan under Minamoto no Yoritomo, was appointed as the jitō (land steward) of Yuki County for his service in suppressing the rebellion of Shida Yoshihiro. It is believed that he built a castle in this area, marking the beginning of the Yuki clan.
Asamitsu adopted the name Yuki Shichirō and became the founder of the Yuki clan. Initially, Yuki Castle is thought to have been about the size of a samurai residence from the Kamakura period, but as the Yuki clan’s power expanded, the castle’s fortifications were also improved.
From the Nanboku-chō Period to the Muromachi Period: The Development of the Yuki Clan
During the Nanboku-chō period, the Yuki clan expanded its power from Shimotsuke Province to northern Hitachi Province, growing into a powerful samurai family. Yuki Castle was also gradually expanded, developing into a formidable fortress.
During the Muromachi period, the Yuki clan established a firm position as a powerful daimyo in the Kanto region. Yuki Castle was not merely a residence, but functioned as the political and military center controlling the entire Yuki County area.
Battle of Yuki (1440-1441): A Historical Stage
The greatest event that etched Yuki Castle’s name into history was the Battle of Yuki, which took place from 1440 (Eikyo 12) to 1441 (Kakitsu 1) during the Muromachi period.
When Ashikaga Mochiuji, the Kamakura Shogun, was overthrown by the Muromachi Shogunate in the Eikyo Rebellion, Yuki Ujitomo and Yuki Mochitomo (father and son) rebelled against the shogunate, supporting Mochiuji’s orphaned son. During this battle, Yuki Castle withstood a siege by the shogunate army for about a year, becoming renowned as an impregnable fortress.
Ultimately, Yuki Castle fell, and Yuki Ujitomo and Mochitomo were killed in battle, but this battle made the castle’s strength widely known. After the battle, the Yuki clan was allowed to be restored and continued until the Sengoku period.
Sengoku Period: The Survival and Transformation of the Yuki Clan
During the Sengoku period, the Yuki clan, surrounded by powerful forces such as the Hojo and Satake clans, maintained their family name through skillful diplomacy. In particular, during the time of Yuki Masakatsu, they maintained their independence while cultivating friendly relations with the Hojo clan of Odawara.
In 1590 (Tensho 18), during Toyotomi Hideyoshi’s siege of Odawara, the Yuki clan sided with the Toyotomi and their territory was secured. However, since Yuki Harutomo had no male heir, he adopted Tokugawa Ieyasu’s second son, Hideyasu.
Edo Period: Yuki Hideyasu, the Abandonment of the Castle, and its Restoration
In 1600 (Keicho 5), after the Battle of Sekigahara, Yuki Hideyasu was transferred to Kitano-sho (Fukui), Echizen Province, with an increased stipend of 670,000 koku. As a result, Yuki Castle was temporarily abandoned, and many of its buildings were demolished.
For approximately 100 years there was no castle in Yuki, but in 1700 (Genroku 13), when Mizuno Katsunaga was granted Yuki with a stipend of 18,000 koku from Noto Province, Yuki Castle was rebuilt as a jinya (fortified residence). From then until the Meiji Restoration, the Mizuno clan remained the lords of the Yuki Domain, and Yuki Castle (jinya) functioned as the domain’s administrative center.
Unlike the castles of the Sengoku period, Yuki Castle during the Edo period had a strong character as a jinya, serving as the center of politics and administration. It used earthen ramparts rather than stone walls and had a relatively simple structure.
After the Meiji Era: Transformation into a Castle Ruins Park
After the Meiji Restoration, the Yuki Domain was abolished due to the abolition of the feudal domains and the establishment of prefectures, and the buildings of Yuki Castle were demolished. The castle ruins became privately owned or public land, and urbanization progressed.
Currently, the site of the former main keep has been developed into Yuki Castle Ruins Park, a place of relaxation for citizens. Remains such as parts of the earthworks and moat traces remain and are protected as a Yuki City designated historical site. The park also features a haiku monument by Yosa Buson, creating a space where one can feel history and culture.
Structure and Layout of Yuki Castle
Location and Topography of the Castle
Yuki Castle is a flatland castle built on a plateau between the Kinugawa and Tagawa rivers. Its elevation is approximately 30 meters, and the difference in height from the surrounding lowlands is about 10 meters, placing it slightly higher. This topographical advantage and the defensive structure utilizing natural moats formed by the rivers are characteristic features.
The Kinugawa River flows to the east of the castle, and the Tagawa River to the west, and these rivers served as outer moats. Furthermore, it is believed that multiple tributaries and irrigation canals surrounded the castle, forming a complex network of water moats.
Layout and Main Enclosures
Yuki Castle is believed to have had a concentric layout with the main enclosure (Honmaru) at its center, surrounded by the second and third enclosures (Ninmaru and Sannomaru). It was relatively large for a medieval castle and possessed a comprehensive defensive structure encompassing the surrounding castle town.
Honmaru: The current Yuki Castle Ruins Park is considered to be the site of the Honmaru. It measured approximately 200 meters east-west and 150 meters north-south, surrounded by earthen ramparts and moats. The Honmaru housed the lord’s residence and other major buildings.
Ninmaru and Sannomaru: While the Ninmaru and Sannomaru were located around the Honmaru, urbanization has progressed, and no clear remains exist today. Edo period maps confirm that the Ninmaru was located to the north and east of the Honmaru, with the Sannomaru outside of that.
Total Fortifications: Yuki Castle possessed a comprehensive defensive structure, surrounding not only the castle grounds but the entire castle town with earthen ramparts and moats. This structure was developed from the late Sengoku period to the early Edo period, serving to strengthen the defenses of the castle town and also to demarcate the merchant and samurai districts.
Characteristics of Defensive Structures
The most distinctive feature of Yuki Castle is its defensive structure, which primarily uses earthen ramparts rather than stone walls. This is a common characteristic of flatland castles in the Kanto region, reflecting the regional difficulty in obtaining stone materials.
The earthen ramparts were approximately 3-5 meters high, and it is believed that walls or fences were built on top. Even today, parts of the earthen ramparts remain in good condition within the castle park, allowing us to imagine the structure at that time.
The moats were mainly water moats, approximately 10-15 meters wide. Water was drawn from the Kinugawa and Tagawa rivers, maintaining a constant water level.
Highlights of Yuki Castle
Yuki Castle Ruins Park
Currently, the site of Yuki Castle’s main keep has been developed into Yuki Castle Ruins Park and is open to the public. The park contains the following points of interest:
Earthwork Remains: Earthworks from the Edo period remain in good condition on the north and east sides of the park.

It is said that Buson composed a haiku at the site of Yuki Castle during a visit to Yuki, and a monument commemorating this has been erected.
