Dogasawa Castle Ruins (Akita Prefecture) Complete Guide: History, Remains, and Access Information
What are the Dogasawa Castle Ruins?
The Dogasawa Castle Ruins are a medieval castle site located in Akita Prefecture. As one of the many medieval castle sites remaining in the Tohoku region, it holds an important position in regional history research.
Medieval Akita was a region where local lords, including the Ando clan, competed for power. The Dogasawa Castle Ruins are thought to be a defensive structure built within this historical context. The castle ruins feature a layout that skillfully utilizes the terrain, making it a valuable cultural asset that conveys the castle-building techniques and regional governance of the time.
Historical Background of the Dogasawa Castle Ruins
Political Situation in Medieval Akita
Medieval Akita experienced a complex political situation from the Kamakura period to the Sengoku period. In particular, the Ando clan expanded its power mainly in northern Akita, and many local lords built castles under their rule.
The construction period of the Dōgasawa Castle ruins is estimated from the form of the remains and excavated artifacts, but it is thought to fall during the late medieval period, roughly between the 14th and 16th centuries. This period was a turbulent time, transitioning from the Nanboku-chō period to the Sengoku period, and local lords needed strong castles to protect their territories.
Builder and Role of the Castle
Regarding the builder of the Dōgasawa Castle ruins, there are no clear documentary records, so we cannot say anything definitively. However, based on the location and the characteristics of the layout, it is presumed that a powerful local lord built it as their residence or a subsidiary castle.
The manor house was not merely a living space, but possessed a variety of functions, including:
- Defensive Base: A military facility prepared for attacks from external enemies
- Administrative Center: A base for managing the territory
- Economic Foundation: Management of surrounding farmland and collection of land tax
- Symbol of Authority: A building demonstrating the lord’s power
Characteristics and Structure of the Remains
Location and Topographical Utilization
The Dōgasawa Manor Site is characterized by its skillful use of natural terrain. Like many medieval castles and manors, it was built in a location with the following topographical advantages:
- Plateau or Hill: High ground offering a panoramic view
- Natural Moat Formed by Rivers and Streams: Enhanced defensive capabilities
- Mountains Behind: Securing retreat routes and supply lines
This location was chosen as a “fortified site” where effective defense was possible even with a small force.
Layout and Major Remains
The layout (castle arrangement plan) of the Dōgasawa Castle site exhibits typical characteristics of a medieval castle. Major remains include the following:
Main Enclosure (Shukaku)
The main enclosure, the central part of the castle, housed the lord’s residence and important facilities. A flat surface, elevated above the surrounding area, enhanced its defensive capabilities. The size of the main enclosure serves as an indicator of the lord’s power and the importance of the castle.
Moats and Earthworks
Moats (dry or water moats) and earthworks were strategically placed as defensive structures. Moats prevented enemy intrusion, while earthworks acted as barriers against arrows and stones. Traces of these defensive structures may remain on the surface of the ground at the Dōgasawa Castle site.
Enclosures (Kuruwa)
Several enclosures (flat sections) are arranged surrounding the main enclosure. These enclosures were used as garrisons for soldiers and storage areas for supplies.
Koguchi (Entrance Gate)
The koguchi, the entrance to the manor, is the most crucial point for defense. Instead of a straight line, it features winding passages and square-shaped spaces (masugata) to make enemy intrusion difficult.
Preservation Status of the Remains
The current state of preservation of the Dōgasawa Manor site varies depending on the surrounding land use. If the area has been developed as farmland or residential land, some of the remains may have been lost. However, if it remains as forest, the surface remains are often preserved in relatively good condition.
Excavation Surveys and Research Results
Previous Survey History
Information regarding archaeological surveys at the Dōgasawa Manor site, including whether or not they have been conducted and details, is managed by the Akita Prefectural Board of Education and the cultural property departments of local municipalities. Generally, the following methods are used in the investigation of medieval castle sites:
- Survey Investigation: Creation of a layout map based on topographic surveying
- Trial Excavation Investigation: Confirmation of remains through partial excavation
- Full-Scale Excavation: Detailed investigation of the layout of remains and the circumstances of artifact discovery
What can be learned from excavated artifacts
Medieval castle sites yield a variety of artifacts that reveal the lifestyle and culture of the time:
Ceramics
Pottery used daily and Chinese porcelain (celadon and white porcelain) brought in through trade indicate the living standards and trade networks of the castle’s inhabitants.
Weapons and Armor
Arrowheads, sword fragments, and parts of armor and helmets indicate the military nature of the castle.
Building Materials
Metal building materials such as nails and staples, and roof tiles (if used) provide clues to estimating the structure and size of the building. #### Daily Life Tools
Cooking utensils such as pots and kettles, millstones, and whetstones reveal the realities of daily life.
Dating and Chronology
The period of the castle’s existence is determined by scientific analysis, such as the style of excavated artifacts and radiocarbon dating. Comparative research with other medieval castle sites in Akita Prefecture is also important in chronological work.
