History and Construction Background of Nagano Castle
Origins of the Nagano Clan and Construction
Nagano Castle was built by the Nagano clan. The Nagano clan’s founder is believed to be Sukemasa, a grandson of Kudo Suketsune, who adopted the name “Nagano” in this area. Kudo Suketsune was a samurai known in the early Kamakura period, and it is thought that his descendants built a castle in this strategic location as they expanded their power in northern Ise Province.
Role in the Sengoku Period
Nagano Castle was built on high ground at an altitude of 540m and a relative height of 360m, offering a panoramic view of the surrounding area. Facing the Iga Road, the castle functioned as an important base for monitoring and controlling the transportation route connecting Ise and Iga Provinces. During the Sengoku period, it is presumed that its importance as a regional control base increased amidst conflicts with surrounding forces such as the Kitabatake and Oda clans.
Castle Changes and Abandonment
Detailed historical records of Nagano Castle are limited, but it is believed to have functioned as the Nagano clan’s base throughout the medieval period. It is presumed that Nagano Castle, like many medieval mountain castles, was abandoned during the process of unifying Japan by Oda Nobunaga and Toyotomi Hideyoshi from the late Sengoku period to the Azuchi-Momoyama period. In the Edo period, flatland castles became the mainstream, and Nagano Castle, as a mountain castle, disappeared from the historical stage.
Structure and Characteristics of the Remains of Nagano Castle
Overall Castle Layout
Nagano Castle began of a main enclosure at an altitude of 520m, with the East Castle, Central Castle, and West Castle built on the nearby hill ridge at an altitude of 230m. This “linked enclosure” layout, where multiple enclosures work together to form a defensive system, is a typical characteristic of medieval mountain castles. Each enclosure is separated by a moat and designed to function as an independent defensive base.
Structure of the Main Enclosure
The main enclosure is located at the highest point of the castle grounds, surrounded by earthen ramparts on three sides except the east. Stepped terraces are arranged around this plateau, forming a multi-layered defensive structure. Multiple enclosures extend westward from the main enclosure, and further remains are found beyond them. The height and thickness of the earthworks suggest that considerable effort was invested in their construction.
Defensive System of Moats and Earthworks
The most distinctive feature of Nagano Castle is its robust defensive system combining moats and earthworks. Particularly to the northeast, there are numerous remains featuring prominent moats and earthworks, demonstrating ingenuity in preventing enemy intrusion. The moats were dug to cut across the ridges, physically hindering the enemy’s advance. The earthworks, on the other hand, functioned as defensive walls while also ensuring visibility from within the castle.
Arrangement of Lower Enclosures
The stepped lower enclosures surrounding the main enclosure were crucial elements in forming a multi-tiered defensive line against attacking enemies. enclosures also served as positions for soldiers and were designed as the last line of defense protecting the main enclosure. The skillful arrangement of the baileys, utilizing the terrain, speaks to the high level of castle-building technology of the medieval mountain castle.
