About Narushima-yakata Ruins (Yamagata Prefecture)
The Narushima-yakata Ruins are the remains of a medieval manor house located in Narushima-cho, Yonezawa City, Yamagata Prefecture. As an important historical site that tells the story of the medieval history of the Okitama region, it attracts attention from local history enthusiasts and researchers.
Overview of Narushima-yakata Ruins
The Narushima-yakata Ruins are located in the southern part of the Yonezawa Basin, in the basin of the Omonogawa River, a tributary of the Mogami River. In the medieval period, this area was a crucial transportation hub and a strategically important military base.
While parts of the manor site are now farmland and residential areas, traces of earthworks and moats remain, allowing us to imagine its former scale.
History of Narushima-yakata Ruins
The Narushima Clan and the Establishment of the Manor
The Narushima-yakata is believed to have been the residence of the Narushima clan, who ruled this area in the medieval period. The Narushima clan was a local powerful family that maintained its influence through its relationships with the Date and Nagai clans, who ruled the Okitama region.
While documentary evidence is limited, historical records confirm that the Narushima clan was active in this region from the 14th to the 15th centuries. It is presumed that the Narushima clan, as local lords, were responsible for managing agricultural production and maintaining public order.
Narushima Residence in the Sengoku Period
During the Sengoku period (Warring States period), the Okitama region became a battleground for the power struggle between the Date and Uesugi clans. It is believed that the Narushima Residence was also under military tension during this period.
In the late 16th century, with the rise of Date Masamune, many minor lords in the Okitama region came under the control of the Date clan. It is presumed that the Narushima clan also became subordinate to the Date clan during this period, but many details remain unclear.
Changes After the Edo Period
In the Edo period, the Uesugi clan came to rule the Okitama region as the lords of the Yonezawa Domain. By this time, Narushima Castle had already been abandoned, and the area surrounding the castle site was developed into farmland.
Development continued after the Meiji Restoration, and today much of the castle site has been converted into residential or agricultural land. However, traces of the castle remain in the topography and place names.
Structure and Remains of Narushima Castle Site
Size and Layout of the Castle
Narushima Castle is believed to have been a flatland castle (hirakan) built on flat ground. Based on archaeological excavations and topographical surveys, the following structure has been estimated:
Main Components:
- Main Enclosure (Honmaru): The living space and central area where the lord of the castle conducted administrative affairs
- Earthworks: Earthen walls built for defense
- Moat: A defensive ditch surrounding the castle
- Entrance (Koguchi): The entrance to the castle
The total area of the castle is estimated to be approximately 2 hectares, a standard size for a local powerful family’s castle in the medieval period.
Existing Remains
Currently, the following remains can be observed at the Narushima Manor site:
Traces of Earthworks:
Traces of earthworks, approximately 1-2 meters high, remain on parts of the north and east sides of the manor. While some areas are covered by trees, they provide valuable clues to estimating the scale of the defensive facilities in their heyday.
Moat Remains:
It is believed that a moat surrounded the manor, and traces of it remain today as depressions and waterways. The moat remains, particularly on the west side, are relatively clear and are estimated to have been approximately 5-8 meters wide and 2 meters deep.
Topographical Undulations:
The central part of the manor site is slightly higher than the surrounding area, which is thought to be the remains of an artificially constructed main enclosure.
