History of Manako Castle
Background of Construction and the Eisho Era
The Eisho era, when Manako Castle was built, was a turbulent period in the Kanto region, marking the beginning of the Sengoku period (Warring States period). The Utsunomiya clan was expanding its power as a powerful daimyo in Shimotsuke Province, but a constant tension existed between them and the Minagawa clan to the south.
Utsunomiya Tadatsuna decided to build a castle on Akabeyama, a strategic point along the road leading from Kanuma to Tochigi, as a defense against the Minagawa clan. The castle was built by Tadatsuna’s illegitimate son, Okamoto Mototsuna (also known as Utsunomiya Mototsuna), with his retainer, Okamoto Hidetaka, appointed as the castle lord.
A Border Castle Between the Utsunomiya and Minagawa Clans
Manako Castle held extremely important strategic value as a “border castle” located at the boundary between the Utsunomiya and Minagawa territories. Situated on the left bank of the Akatsugawa River, it is believed to have served to monitor the Minagawa territory to the south and to prepare for invasions from the Kanuma area.
The castle’s location, on high ground that allowed for easy monitoring of enemy movements and its position controlling the road, made it a strategically important base both militarily and logistically. It is presumed that the Utsunomiya clan formed a defensive line centered around this castle, along with a group of branch castles belonging to the Nishikata clan and others.
Changes in the Sengoku Period
Throughout the 16th century, Manako Castle was under the control of the Utsunomiya clan. However, in the later Sengoku period, the situation in Shimotsuke Province became complicated due to the expansion of the Hojo clan’s power. While the Utsunomiya clan sought to align itself with the Hojo clan, the Minagawa clan also pursued its own independent diplomatic policies.
During Toyotomi Hideyoshi’s siege of Odawara in 1590, Minagawa Hiroteru initially sided with the Hojo clan, but escaped Odawara Castle and secretly allied himself with the Toyotomi through Tokugawa Ieyasu, thus securing his territory. While there are no clear records of the role Manako Castle played during this period, it is thought that its strategic importance changed as the relationship between the Utsunomiya and Minagawa clans shifted.
Abandonment of the Castle and its Aftermath
During the Edo period, many branch castles were abandoned due to the shogunate’s policies, such as the “One Castle Per Province” decree. It is presumed that Manako Castle was also abandoned during this period, but the exact date of its abandonment is unclear due to a lack of historical records.
After its abandonment, the castle site was left as a forest for a long time. Fortunately, it avoided large-scale development, resulting in the preservation of its Sengoku period layout in good condition.
Layout and Structure of Manako Castle
Overall Layout
Manako Castle is a mountain castle with a complex layout, centered on the summit of Mt. Akabe, with multiple baileys and trenches arranged on the north, west, and south ridges. Defensive facilities are arranged radially from the main bailey, designed to withstand attacks from multiple directions.
The castle area covers a relatively wide area, and numerous trenches and vertical moats blocking the ridgelines can be observed, in addition to the main baileys. These remains demonstrate the advanced castle-building techniques of the time and indicate that this castle was not merely a lookout post, but a full-fledged mountain castle designed for actual combat.
Main Enclosure and Surroundings
The main enclosure, located at the mountaintop, is the core of the castle. It has a relatively large, flat area, and it is presumed to have been the residence of the castle lord or castellan. Traces of earthworks are found around the main enclosure, indicating measures taken to enhance its defensive capabilities.
From the main enclosure, there are expansive views of the surrounding area, overlooking the Minagawa area to the south and the roads to the east and west. This excellent view indicates its character as a border castle that emphasized surveillance.
Arrangement of Enclosures
Several enclosures are arranged in a stepped pattern surrounding the main enclosure. These enclosures form a defensive line to prevent approach to the main enclosure, creating multiple barriers before the enemy could reach it.
The size of each enclosure varies; larger enclosures were likely used for troop garrisons and supply storage, while smaller enclosures functioned as watchtowers and defensive positions. The elevation differences between enclosures were also utilized as defensive elements, demonstrating ingenuity in making it difficult for attackers to advance.
Moats and Vertical Moats
One of the greatest highlights of Manako Castle is its well-preserved group of moats. Deep moats completely blocking the ridges on the north, west, and south sides served to physically prevent enemy incursions.
The moat on the northern ridge, in particular, is large and sufficiently deep, making it easy to imagine its original appearance. Furthermore, several vertical moats extending from the moats down the slopes can be observed, indicating ingenuity in restricting lateral movement.
These moats and vertical moats are valuable relics demonstrating the castle-building techniques of the mid-Sengoku period and hold high value from the perspective of castle research.
Features of the Defensive System
The defensive system of Manako Castle exhibits the typical style of a Sengoku period mountain castle, skillfully utilizing the terrain. The steep slopes themselves act as natural barriers, and the defensive capabilities are further enhanced by artificial moats and earthworks.
The main approach routes to the castle are limited, forcing attackers to pass through moats and baileys. This “depth defense” concept is a rational design for defending against a large number of enemies with a small number of defending forces.
Highlights of Manako Castle
Well-Preserved Remains
The greatest attraction of Manako Castle is undoubtedly its well-preserved remains. Having escaped large-scale development, the original layout remains almost entirely intact, making it a valuable historical site where one can experience the appearance of a Sengoku period mountain castle.
The depth of the moats and the elevation differences of the baileys are particularly clear, making it a popular spot for photography. Among castle enthusiasts, it is highly regarded as a “castle that conveys magnificent remains.”
Scenic Viewpoints
The views from near the main enclosure are not to be missed. On a clear day, you can enjoy a panoramic view of Minagawa to the south and the city of Tochigi, allowing you to imagine what the castle lords once saw from this spot.

Along the ascent, you can observe remains such as vertical moats and lower enclosures, gaining a firsthand understanding of the castle’s defensive system. The round trip takes approximately 1 to 1.5 hours.
Seasonal Expressions
Manako Castle displays different expressions throughout the four seasons. Each season offers different discoveries when visiting: spring brings fresh greenery and wildflowers, summer offers deep green, autumn brings vibrant autumn leaves, and winter, with fallen leaves making the ruins easier to see.
In particular, winter is the best time to observe the shapes of moats and earthworks because the leaves have fallen from the trees. For those studying castles or taking photographs, a winter visit is recommended.
