Hanazono Mitake Castle (Saitama Prefecture) Complete Guide: A Thorough Explanation of the History and Remains of the Fujita Clan’s Branch Castle
Hanazono Mitake Castle is a medieval mountain castle located in Yorii-machi, Osato-gun, Saitama Prefecture. As a branch castle of Hanazono Castle, the residence of the Fujita clan who played a significant role in the Sengoku period of Musashi Province, it played a crucial role in its defense. This article comprehensively explains the appeal of the castle ruins, from its historical background and castle structure to its existing remains and a visitor’s guide.
Overview and Location of Hanazono Mitake Castle
Basic Information
Hanazono Mitake Castle is a mountain castle built on the summit of Mount Mitake, at an altitude of 247 meters. It is situated in a strategic location between the Arakawa River and Lake Enryoda, approximately 500 meters northwest of Hanazono Castle. Because of its higher elevation than Hanazono Castle, it is believed to have been built to monitor and defend against attacks from the rear.
Location: Hanazono, Yorii-machi, Osato-gun, Saitama Prefecture
Castle Classification: Mountain Castle
Builder: Fujita clan (estimated)
Relative Height: Approximately 90 meters
Main Remains: Horizontal moat, vertical moat, earthworks, earthen bridge, inner square enclosure
Geographical Importance
The location of Hanazono Mitake Castle indicates a strategically important point in Musashi Province. Situated overlooking the transportation routes of the Arakawa River basin, it functioned as a fort responsible for the rear defense of Hanazono Castle. While the main castle, Hanazono Castle, is located near the plains at the foot of the mountain, Mitake Castle is situated on a steep mountaintop, presumably to have played a role in detecting enemy movements early and preventing surprise attacks from the rear.
History of Hanazono Mitake Castle
The Fujita Clan and Hanazono Castle
To understand the history of Hanazono Mitake Castle, it is necessary to first learn about the Fujita clan and Hanazono Castle. The Fujita clan was a prominent family that served as important retainers of the Yamanouchi Uesugi clan, the Kanto Kanrei (governor of the Kanto region), and their ancestral home was Hanazono Castle. The Fujita clan wielded considerable power in northern Musashi Province and played a crucial role as a political and military cornerstone in the Kanto region during the Sengoku period.
Relationship with the Hojo Clan
In the mid-Sengoku period, the Fujita clan deepened their relationship with the Odawara Hojo clan. Fujita Yasukuni adopted Hojo Ujikuni, the fifth son of Hojo Ujiyasu, and had him inherit the headship of the Fujita clan. Hojo Ujikuni later moved his base to Hachigata Castle, but Hanazono Castle continued to be used as a subsidiary castle. It is believed that Hanazono Mitake Castle was also maintained during this period as part of the defense system of Hanazono Castle.
Lack of Documentary Records
Interestingly, there are no existing clear documentary records concerning Hanazono Mitake Castle. Even the official documents of Yorii Town explicitly state, “No documentary records exist.” However, the form and arrangement of the castle remains leave no doubt that it was a subsidiary castle that functioned at the same time as Hanazono Castle. The lack of documentation may be because Mitake Castle was perceived as part of Hanazono Castle’s defensive facilities rather than as an independent castle.
Period of Abandonment
The exact date of abandonment of Hanazono Mitake Castle is unclear, but it is presumed to have been abandoned along with Hanazono Castle when the Hojo clan was destroyed during Toyotomi Hideyoshi’s Odawara campaign in 1590. Hachigata Castle also fell in this battle, and the castles in northern Musashi Province, which had been under Hojo control, all disappeared from the historical stage.
Castle Structure and Layout
Main Enclosure (Honmaru)
The main enclosure of Hanazono Mitake Castle is located on the summit of Mount Mitake, and currently houses the Mitake Shrine. The main enclosure is a relatively flat, leveled area, providing space for the shrine’s main building. The main enclosure is not particularly large, but it is spacious enough for a mountain castle fort.
The existence of the Ontake Shrine has played an important role in the preservation of the castle ruins. Because it has been maintained as an object of worship, the remains have survived to the present day without being destroyed.
Horizontal and Vertical Moats
The greatest highlight of Hanazono Ontake Castle is the well-preserved horizontal moat. A clear horizontal moat runs from the southeast to the southwest of the main enclosure. This horizontal moat is thought to have prevented enemy intrusion and also functioned as a movement route within the castle.
Vertical moats have also been confirmed, dug vertically into the mountain slope. Vertical moats are effective in preventing enemies from climbing the slope and are important defensive structures unique to mountain castles. The vertical moats of Hanazono Ontake Castle demonstrate the skillful use of terrain in castle construction techniques of the Sengoku period.
Earthworks and Earthen Bridges
Parts of earthworks remain within the castle grounds, conveying the former defensive line to the present day. Earthen ramparts are earthen walls built by piling up soil, serving to prevent enemy intrusion and also obstructing the view from within the castle.
The earthen bridges crossing the moats are also well-preserved. Earthen bridges are bridges for crossing moats, usually constructed by piling up earth. This structure limits enemy intrusion routes, giving the defenders an advantage. The earthen bridges at Hanazono Mitake Castle are relics that demonstrate the ingenuity of the castle’s layout at the time.
Inner Masugata
The remains of an inner masugata (square enclosure) can also be seen. A masugata is a structure designed to strengthen the defense of a castle gate, luring the enemy into a narrow space for attack. The presence of such sophisticated defensive structures in a subsidiary castle of a mountain castle indicates that Hanazono Mitake Castle was not merely a lookout post, but a full-fledged military facility designed for actual combat.
Characteristics of the Defensive System
Hanazono Mitake Castle’s layout, though small in scale, features an efficient defensive system. By utilizing the natural fortifications of the mountaintop while combining artificial defensive structures such as horizontal moats, vertical moats, earthworks, and square enclosures, this castle was designed to prevent enemy incursions even with a small number of defenders.
This castle was built with the clear purpose of being a “fort to protect the rear” of Hanazono Castle, and its layout is specifically designed for that purpose. It is clear from the remains that it was not an independent castle, but rather a subsidiary castle intended to work in conjunction with Hanazono Castle.
Current Status and Preservation of the Remains
Well-Preserved Remains
The remains of Hanazono Mitake Castle are relatively well-preserved for a medieval mountain castle. In particular, the horizontal moats and earthen bridges are clearly visible, allowing visitors to directly experience the castle structure of the Sengoku period. Partial earthworks also remain, making it possible to imagine the defensive lines of the time.
The presence of the Mitake Shrine on the mountaintop has positively contributed to the preservation of the remains. The well-maintained approach to the castle makes it easy to climb, and the fact that it has been cherished as a place of worship likely contributed to the preservation of the remains.
Evaluation of the Remains
Castle researchers and enthusiasts generally rate the remains at around “★★★☆☆” (3 out of 5). While smaller in scale compared to large mountain castles, the remains are sufficient to understand its function as a subsidiary castle, and it is considered to have high academic value.

The Charm and Highlights of Hanazono Mitake Castle
A Mountain Castle Evoking Historical Romance
The greatest charm of Hanazono Mitake Castle is that it retains the appearance of a subsidiary castle from the Sengoku period in excellent condition. Although documentary records are scarce, the remains themselves eloquently tell the history of that time. The relative location to the main castle, Hanazono Castle, the ingenuity of its layout, and the placement of its defensive structures allow us to decipher the castle network and defensive strategies of the Sengoku period.
Harmony with Nature
The natural environment of Mount Ontake is also one of its attractions. The view from the summit is magnificent, offering a panoramic view of the Arakawa River basin. You can enjoy the changing seasons, from fresh greenery in spring to vibrant autumn leaves, while exploring the castle ruins. The area is also developed as a hiking trail, making it a place where you can enjoy both historical exploration and nature walks simultaneously.
The Serene Atmosphere of Ontake Shrine
The Ontake Shrine at the summit adds a sacred atmosphere to the castle ruins. The fact that this site, once a fort during the Sengoku period, is now a place of worship cherished by people, allows us to feel the passage of history. Observing the remains from the shrine grounds allows us to appreciate the layered nature of different eras: military and religious facilities.
Value for Castle Research
Hanazono Ontake Castle is a valuable example for the study of subsidiary castles. This site is important for understanding the realities of the Sengoku period, where not only large main castles but also these smaller branch castles cooperated to control the region. Although the scale of the remains is small, their academic value is by no means low.
Hanazono Mitake Castle and the Defense System of Hanazono Castle
Branch Castle Network
Hanazono Mitake Castle played a part in a network of branch castles centered around Hanazono Castle. Branch castles such as Toragaoka Castle were also located around Hanazono Castle, and these worked together to defend the area.
Hanazono Mitake Castle played a particularly important role as a “rear defense.” Because Hanazono Castle was located near the plains at the foot of the mountain, it was vulnerable to attacks from the mountains behind. Mitake Castle was built in a position to complement this weakness, functioning as a fort to monitor enemy movements and defend when necessary.
Communication and Communications
The distance between Hanazono Castle and Hanazono Mitake Castle was approximately 500 meters, allowing for rapid communication via smoke signals and messengers. If enemy approach was detected at Mitake Castle, it could be immediately reported to Hanazono Castle, making it easy for Hanazono Castle to dispatch reinforcements to Mitake Castle. This proximity is thought to have made the coordination between the two castles effective.
Utilization of Elevation Differences
The fact that Hanazono Mitake Castle is located at a higher elevation than Hanazono Castle was strategically important. From higher ground, enemy movements could be observed over a wide area, functioning as an early warning system. Furthermore, higher ground is advantageous for defense, making it easier to repel enemy attacks even with a small force.
