History of Tokiwa Castle
From the Castle’s Construction to the Kumagai Clan Era (1274-)
Tokiwa Castle is said to have been built in 1274 by Kumagai Naonori. The Kumagai clan is believed to be descended from Kumagai Naozane of Musashi Province, who played an active role in the Genpei War, and they expanded into the Tohoku region during the Kamakura period. It is thought that by establishing a castle in Tokiwa, they solidified their control over the region.
The Kumagai clan used Tokiwa Castle as their base for several generations, but detailed records are scarce, and many aspects of their specific activities remain unclear.
From the Akamatsu Clan to the Tokiwa Clan
After the Kumagai clan, the Akamatsu clan became the castle lords. The Akamatsu clan was a prominent family based in Harima Province (present-day Hyogo Prefecture), but it is believed that a branch of the family that expanded into the Tohoku region became the lord of Tokiwa Castle. The Akamatsu clan changed their surname to “Tokiwa,” adopting a surname derived from the place name. This followed the custom of medieval samurai adopting the place name of their territory as their surname.
The Tokiwa clan ruled this area for several generations, but a major turning point occurred during the time of Tokiwa Sadahisa.
Tamura Clan Rule and Ishizawa Clan’s Entry
During the Sengoku period, the area around Tokiwa Castle was within the sphere of influence of the Tamura clan, whose base was Miharu Castle. Tamura Kiyoaki is known as a brilliant general who built the Tamura clan’s golden age, and he successively brought the surrounding minor lords under his control.
During the time of Tokiwa Sadahisa, Tamura Kiyoaki captured Tokiwa Castle, driving the Tokiwa clan from their position as castle lords. Afterward, Ishizawa Shuri-no-suke, a senior retainer of the Tamura clan, entered the castle as its lord, and it began to function as a branch castle under the Tamura clan.
The Ishizawa clan was known as an influential retainer of the Tamura clan, and it is believed that they played a role in the Tamura clan’s eastern defense from Tokiwa Castle.
The Fall and Abandonment of Tokiwa Castle in 1589
In 1589, Tokiwa Castle faced a fateful moment. That year, following the death of Tamura Kiyosuke, the head of the Tamura clan, surrounding forces intervened in the succession dispute, creating a complex political situation.
Taking advantage of this chaos, a combined force of the Soma and Iwaki clans invaded the Tamura territory. Tokiwa Castle became a target, and a fierce battle ensued. According to records, the castle was attacked with fire by both armies, burned down, and fell.
With this fall, Tokiwa Castle was abandoned and never used as a castle again. With the end of the Sengoku period, the history of Tokiwa Castle, spanning over 300 years, came to an end.
Subsequent Changes
After the Edo period, the Tokiwa Castle ruins were largely neglected, but in modern times, they began to attract attention as a regional historical heritage site. Currently, the site is maintained as Tateyama Park and serves as a place of relaxation for citizens.
A replica castle tower stands on the mountaintop, serving as a symbol that conveys the history of Tokiwa Castle. While this replica tower is not based on historical fact, it is a beloved local landmark.
Tokiwa Castle’s Layout and Structure
Location and Topography
Tokiwa Castle is a typical mountain castle built on the summit of Tateyama, overlooking the town of Tokiwa. Utilizing the mountaintop at an altitude of approximately 400 meters, it occupies a strategic position offering panoramic views of the surrounding plains.
As a mountain castle, its location follows the fundamental principles of medieval castles: early detection of enemy movements and maximizing the use of advantageous terrain for defense. The steep slopes acted as natural fortifications, making it a formidable fortress that was difficult for attackers to conquer.
Layout of the Enclosures
The center of Tokiwa Castle was the Honmaru (main enclosure) at the mountaintop, where the lord’s residence and important facilities are believed to have been located. Currently, a replica keep stands on the site of the Honmaru.
Across the Honmaru, multiple enclosures (kuruwa) were arranged in a stepped pattern. These enclosures served as defensive strongholds, as well as troop encampments and storage areas for supplies.
Each enclosure was separated by steep slopes called kirigishi (cut cliffs), designed to prevent easy movement by the enemy.
Moats and Defensive Structures
Multiple moats (horikiri) have been identified as important defensive structures of Tokiwa Castle. These moats, dug to cut across ridges, played a crucial role in preventing enemy incursions.
The moats that remain clearly visible today demonstrate the advanced civil engineering techniques of the time and speak to the meticulous attention paid to the castle’s defenses. Moats several meters deep would have been a significant obstacle for attackers.
Furthermore, earthen ramparts were constructed in various places, surrounding the baileys and enhancing their defensive capabilities. It is presumed that fences or walls were built on top of these ramparts.
Entrances and Passages
The entrances to the castle, known as koguchi, were the most important defensive structures. At Tokiwa Castle, it is believed that the koguchi had a complex structure to prevent easy enemy intrusion.
The passages connecting the baileys were also designed to be winding rather than straight, a design intended to slow down the enemy’s advance.
Remains of Tokiwa Castle
Existing Remains
Currently, the following remains can be observed at the Tokiwa Castle site:
Baileys: Multiple baileys, centered around the main keep, remain despite changes in the terrain. While some alterations were made during the development of the park, the basic layout evokes the castle’s former appearance.
Moat: One of the best-preserved remains, several clear moats cutting across the ridge can be observed. Their depth and width allow us to understand the defensive strategy of the time.
Earthwork: Parts of the earthworks built around the baileys remain. Although their height is low, their arrangement allows us to estimate the defensive line.
Cliff: Cliffs separating the baileys remain in various places, revealing artificially carved steep slopes.
Replica Castle Tower
A two-story replica castle tower stands on the site of the main bailey at the mountaintop. This tower is not based on historical evidence but was constructed as a tourist attraction. During the Sengoku period, when Tokiwa Castle actually existed, castle towers were rarely built on mountain castles in the Tohoku region.
However, this replica castle tower plays an important role as a symbol of Tateyama Park and as a facility to widely disseminate the history of Tokiwa Castle. From the castle tower, you can enjoy a panoramic view of Tokiwa city and the surrounding mountains, allowing you to imagine the scenery seen by the castle’s former lords.
Preservation Status of the Ruins
While some of the ruins have been altered due to the park’s development, the main defensive structures, such as the moats and cliffs, are preserved in relatively good condition.
In recent years, the historical value of castle ruins has been re-recognized, and awareness of preservation has increased. A more appropriate balance between preservation and utilization will be required in the future.
Current State as Tateyama Park
Park Development
The Tokiwa Castle ruins are now developed as Tateyama Park, a popular recreational area for citizens. Walking paths have been constructed, making it relatively easy to access the replica castle tower at the mountaintop.
Cherry trees are planted within the park, making it a popular spot for cherry blossom viewing in spring. The combination of the castle ruins and cherry blossoms embodies traditional Japanese aesthetics, captivating many visitors.
Views
The views from the mountaintop are magnificent, offering a panoramic view of Tokiwa city, and on clear days, the mountains of the Abukuma mountain range can be seen in the distance. This view was one of the reasons why the castle lords of the Sengoku period considered Tokiwa Castle so important.
By surveying the surrounding terrain, you can truly appreciate why the castle was built in this location and what its strategic value was.
