Takami Castle (Saitama Prefecture) Complete Guide | A Thorough Explanation of the History, Remains, and Access to Yotsuyama Castle
What is Takami Castle?
Takami Castle (Takami-jo) is a medieval mountain castle located in Takami, Ogawa-machi, Hiki-gun, Saitama Prefecture. Also known as Yotsuyama Castle or Yotsuyama Castle, it is built on the summit of Yotsuyama Mountain, at an elevation of 197m and a relative height of approximately 100m. Located approximately 3.5km north of Ogawa-machi Station on the Tobu Tojo Line, it is known as a typical mountain castle situated on an isolated peak in the northernmost part of the Hiki Hills.
The castle site is designated as a Saitama Prefecture Historic Site, and currently, Yotsuyama Shrine is located in the main enclosure at the summit. Because a path leading up to the castle is maintained as the shrine’s approach, it is relatively easy to visit the castle site. Among the medieval mountain castles in the Kanto region, Takami Castle stands out for its remarkably well-preserved remains, making it a valuable historical site where defensive structures such as baileys, earthworks, and moats can be clearly observed.
History of Takami Castle
Construction and Early History
While there are various theories regarding the construction date of Takami Castle, tradition holds that it was built in Jisho 4 (1180) by Ishii Kurouemon Masatsuna. Ishii Masatsuna is said to have been a retainer of Aoki Ujihisa, the lord of Aoyama Castle.
However, since a letter written by Ota Dokan in Bunmei 12 (1480) mentions “Takami” and “Takami Zaibanshu,” the actual construction period is thought to be the latter half of the 15th century. During this period, Takami Castle is believed to have functioned as a branch castle of Hachigata Castle (Yorii Town), which belonged to the Yamanouchi Uesugi clan.
The Bunmei Era and Changes in Castle Lords
Records indicate that during the Bunmei era (1469-1487), Masuda Shiro Shigetomi was the castle lord. During this period, the conflict between the Ogigayatsu Uesugi and Yamanouchi Uesugi clans intensified in Musashi Province, and Takami Castle was a crucial stronghold located on the front lines between these two forces.
From the castle ruins, one could see the entire Arakawa River basin to the north and the Ichinogawa River basin to the south, functioning as a strategic point for monitoring and controlling the Old Kamakura Road (Upper Route) that ran along the Ichinogawa River. During the Sengoku period, it is believed to have played an important role in controlling transportation routes, situated between Hachigata Castle and Matsuyama Castle (Yoshimi Town).
The Battle of Takamigahara and the Castle’s Role
The most important event in the history of Takami Castle is the Battle of Takamigahara. This battle took place in two separate battles.
The First Battle of Takamigahara took place in 1488 (Chōkyō 2). In this battle, a clash between the Ōgigayatsu Uesugi and Yamanouchi Uesugi clans, Takami Castle is believed to have played a crucial role in protecting the Yamanouchi Uesugi’s rear.
The Second Battle of Takamigahara occurred in 1491 (Entoku 3). During this period, the conflict between the two Uesugi clans was at its most intense, and the area around Takami Castle became a fierce battleground. It is presumed that the castle functioned as a frontline base for the Yamanouchi Uesugi clan, serving as a defensive stronghold to hinder the advance of the Ōgigayatsu Uesugi.
History of the Castle’s Abandonment
While there are no clear records regarding the year Takami Castle was abandoned, it is believed to have ceased its role in the late Sengoku period, coinciding with the expansion of the Hōjō clan’s power. During Toyotomi Hideyoshi’s siege of Odawara in 1590, when Hachigata Castle fell, it is presumed that Takami Castle, a subsidiary castle of Hachigata Castle, also lost its function and was abandoned.
Takami Castle’s Layout and Structure
Overall Layout
Takami Castle is a multi-bailey mountain castle built around the summit of Yotsuyama Mountain. It is believed to have been named “Yotsuyama” (meaning “four peaks”) due to the mountain’s shape, and its layout takes advantage of the distinctive topography, where multiple peaks can be seen even from a distance.
The castle grounds consist of a main bailey (honkuruwa), with multiple baileys arranged in a stepped pattern. Maximizing the advantage of its location with a relative elevation of 100m, it forms a long, narrow castle area running north-south.
Characteristics of the Main Bailey (Honkuruwa)
The main bailey located at the summit is the core of Takami Castle, and currently houses the shrine of Yotsuyama Shrine. The main bailey forms a relatively large, flat area, and it is thought to have been the location of the lord’s residence and command post. The main enclosure is surrounded by remnants of earthworks, confirming its defensive function. Although partially altered by the construction of a shrine, it still retains the basic structure of a medieval mountain castle’s main enclosure.
Moats and Defensive Structures
One of the greatest highlights of Takami Castle is its well-preserved moats. The moats separating the main and secondary enclosures are clearly defined in both depth and width, and their function as defensive structures to prevent enemy intrusion is still evident.
Moats are present in multiple locations, allowing observation of typical mountain castle defensive techniques that cut off the ridgeline. The moat behind the main enclosure is particularly large, suggesting its crucial role in the castle’s defense.
Enclosure Arrangement and Terraced Structure
Several enclosures (kuruma) are arranged around the main enclosure. These enclosures are arranged in a terraced fashion, following the mountain’s terrain, and each functioned as an independent defensive unit.
Each enclosure is clearly demarcated by steep slopes, creating a defensive structure that utilizes the difference in elevation. Traces of the castle’s enclosures can be seen on both sides of the path leading to the shrine, giving a glimpse into the castle’s former scale.
Earthworks and Cut Slopes
Earthworks remain in various places within the castle grounds. These earthworks were built along the edges of the enclosures, enhancing defenses and also providing visibility from within.
Cut slopes (artificially carved steep slopes) are also well-preserved, demonstrating ingenuity in making enemy intrusion difficult. These remains are protected by the prefecture’s designation as a historical site and are maintained in an easily observable condition through appropriate upkeep.
Highlights and Points of Interest at Takami Castle
Yotsuyama Shrine and Approach
The starting point for visiting Takami Castle is the approach to Yotsuyama Shrine. Because it is a well-maintained path for worshipping at the shrine, stairs are provided, making it relatively easy to climb to the summit.
As you ascend the approach to the shrine, you can experience firsthand the elevation changes and steep slopes of the castle’s enclosures, gaining a tangible understanding of its structure. The fact that the shrine maintains the access path is fortunate from the perspective of preserving the castle ruins.
Stunning Views
From the main enclosure at the summit, a 360-degree panoramic view unfolds. You can see the entire Arakawa River basin to the north and the Ichinogawa River basin to the south, and on clear days, you can even see the distant Chichibu Mountains.
This excellent view is precisely why Takami Castle was chosen as a strategic stronghold. Its location, allowing for monitoring of the surrounding terrain and early detection of enemy movements, was ideal for a medieval mountain castle. Views towards Hachigata Castle and Matsuyama Castle are also unobstructed, highlighting its role as a communication hub connecting the two castles.
Preservation of the Remains
Takami Castle is protected as a Saitama Prefecture designated historical site, and the remains are in extremely good condition. Defensive structures such as moats, earthworks, baileys, and steep slopes remain clearly visible, making it a valuable resource for learning about the structure of medieval mountain castles.
Moderate maintenance makes exploring the remains easy, and because excessive alterations have not been made, it is easy to imagine its original appearance. It is a castle site that can be enjoyed by everyone from beginners to advanced mountain castle enthusiasts.
Presence as an Isolated Peak
Yotsuyama is an isolated peak that rises remarkably high from its surroundings, and its shape can be seen from afar. This topographical feature not only makes it easy to grasp the castle’s location but also allows us to imagine the castle’s imposing presence in its heyday.
The sight of Yotsuyama rising from the plains is impressive, and one can sense the psychological intimidating effect this castle had during the Sengoku period.
