Kitsunezaki Castle is located northeast of Kamaishi City Hall and is built on a steep mountain ridge visible from the city center.

History of Kitsunezaki Castle
Muromachi Period: As the Residence of the Kitsunezaki Clan
Kitsunezaki Castle is believed to have been built in the mid-Muromachi period. The builder is said to have been Kitsunezaki Genba, a retainer of the Asanuma clan of Tono, who established his power as a local powerful family. According to records from the Muromachi period, after residing at Kitsunezaki Castle, Kitsunezaki Genba moved to the affiliated Ushimura (present-day Kamaishi City area).
During this period, the south side of Kitsunezaki Castle was bordered by the sea, and the castle was located in a strategically important location close to the coastline. This suggests a strategic location that allowed for monitoring both maritime and land routes.
Sengoku Period: A Base for Regional Control
During the Sengoku period, Kitsunezaki Castle continued to function as a base for powerful local families. Later, it is said that Aratani Higo served as the castle lord for a period. During this period, the Sanriku coastal region, while under the influence of powerful clans such as the Nanbu and Date, was also dominated by smaller local families who maintained their own independent systems of governance.
It is believed that Kitsunezaki Castle served as one of these regional strongholds, playing a role in governing and defending the surrounding area.
From the Early Modern Period Onward: The End of its Role as a Castle
In the Edo period, Kitsunezaki Castle lost its military role as a fortress and was abandoned. However, its topographical features remained, and it is preserved to this day as a historical site that conveys the region’s history.
The Layout and Structure of Kitsunezaki Castle
Design of a Mountain Castle Utilizing the Topography
Kitsunezaki Castle is a typical mountain castle built on a steep mountain ridge with a relative height of approximately 90 meters. A flat area was created on the mountaintop by leveling the ridge, resulting in a defensive structure that skillfully utilizes the natural terrain.
The basic structure of the castle consists of a moat separating the rear, followed by the arrangement of about four enclosures (kuruma) in a southwest direction along the terrain. This layout is designed to prevent enemy intrusion while allowing each enclosure to support the others.
Major Remains
Enclosures (Kuruwa): Multiple flat areas can be identified on the mountaintop and along the ridge. The largest flat area, considered the main enclosure, is presumed to have been used as the lord’s residence or command post.
Moat: The moat, constructed to protect the castle’s rear (northeast side), was an important defensive structure to prevent enemy intrusion along the ridge. It can still be seen as a geographical feature today.
Cliffs: Steep slopes are formed around each enclosure, and these are highly likely to be artificially carved cliffs.
Defensive Structure Deciphered from the Layout Map
The layout map of Kitsunezaki Castle shows a stepped arrangement of enclosures descending from the main enclosure on the mountaintop. This stepped arrangement allows for fire support from the upper enclosures to the lower ones, reflecting a typical defensive philosophy of medieval mountain castles.
Furthermore, given its highly visible location from the sea, it’s possible it also functioned as a lookout post or signal fire station.
Highlights and Visitor Guide to Kitsunezaki Castle
Ascent Route and Time Required
To reach Kitsunezaki Castle, use the mountain trail from the Kamaishi city side. Due to the steep terrain with a relative elevation of 90 meters, a certain level of physical fitness is required for the ascent. The average visit takes about 15 minutes, but if you want to carefully observe the remains, allow 30 minutes or more.
The mountain trail is well-maintained, but there are steep sections, so we recommend wearing comfortable clothing and non-slip shoes.
View from the Main Enclosure
From the main enclosure at the summit, a magnificent view unfolds, overlooking Kamaishi city and Kamaishi Bay. This is a valuable point where you can experience the scenery that the castle lords must have seen. On a clear day, you can see all the way to the horizon of the Pacific Ocean.
This excellent view was important for military surveillance, but it is now also utilized as a tsunami evacuation site.
Observation Points for the Ruins
When visiting the castle ruins, paying attention to the following points will help you understand the structure of Kitsunezaki Castle more deeply:
- Size and arrangement of flat areas in each enclosure: Observing the relationship between the main enclosure and the secondary enclosure reveals the functional layout of the castle.
- Depth and width of the moat: You can appreciate how important the defense of the rear was.
- Steepness of the cliffs: Distinguishing between natural terrain and artificial processing helps understand the castle construction techniques.

Modern Role as a Tsunami Evacuation Site
Lessons from the Great East Japan Earthquake
Kamaishi City also suffered significant tsunami damage during the Great East Japan Earthquake on March 11, 2011. Based on this experience, Kitsunezaki Castle ruins have been officially designated as a tsunami evacuation site.
During the earthquake, power outages in Kamaishi disrupted accurate information from the Japan Meteorological Agency. The only information released after the earthquake was a predicted tsunami height of “over 3 meters for Iwate Prefecture,” and warnings for tsunamis were issued based on this information. The actual tsunami far exceeded this prediction, resulting in numerous casualties.
This experience highlighted the importance of rapid evacuation to higher ground, leading to the development of elevated areas like the Kitsunezaki Castle ruins as evacuation sites.
Balancing Historical Heritage and Disaster Prevention Functions
The Kitsunezaki Castle ruins fulfill a challenging role: preserving its value as a historical castle ruin while also serving modern disaster prevention functions. Evacuation routes have been developed and guide signs installed, with careful consideration given to avoiding damage to the ruins.
These efforts are attracting attention as a pioneering example of balancing cultural property preservation with regional safety.
