History of Hobara Castle
Kamakura Period: Legend of Founding
It is said that Hobara Castle was founded by the Date clan in the early Kamakura period, but no historical records remain to confirm this. The Date clan was a prestigious samurai family that expanded its power from the northern part of present-day Fukushima Prefecture to the southern part of Miyagi Prefecture from the Kamakura period to the Muromachi period, and it is believed that the Hobara area was under the influence of the Date clan from an early stage.
Sengoku Period: Base of a Date Clan Vassal
Historical records confirm that Hobara Castle functioned as an important branch castle of the Date clan during the Sengoku period.
Nakajima Ise (Nakajima Munemoto)
Records show that Nakajima Ise (Nakajima Munemoto), a vassal of the Date clan, resided at Hobara Castle during the Tensho era (1573-1592). Nakajima Munemoto is known as a warrior who frequently achieved military success in battles between the Date clan and the Soma clan. The Soma clan was a powerful rival force located to the east of the Date clan, and military clashes frequently occurred between them. Hobara Castle played a crucial role as a base for the Date clan’s eastern defenses.
Kaketa Gozen
Records indicate that a woman named Kaketa Gozen resided at Hobara Castle. During the Sengoku period, women sometimes managed castles and territories, suggesting that Kaketa Gozen, as a figure connected to the Date clan, governed the Hobara area.
Ouchi Sadatsuna
During the time of Date Masamune, Ouchi Sadatsuna is said to have briefly ruled Hobara Castle. Ouchi Sadatsuna was one of Date Masamune’s generals and played a significant role in Masamune’s unification of Oshu. The fact that Hobara Castle was given to a retainer of Masamune indicates its importance to the Date clan.
Momoyama Period: Renovation by Uesugi Kagekatsu
In 1598 (Keicho 3), when Uesugi Kagekatsu entered Aizu with a domain of 1.2 million koku by order of Toyotomi Hideyoshi, the Hobara area also became part of the Uesugi clan’s territory. Uesugi Kagekatsu made Aizu-Wakamatsu Castle (Tsuruga Castle) his base and proceeded to improve the surrounding branch castles.
Hobara Castle was also renovated during this period, strengthening its function as a base for the Uesugi clan’s eastern defense. During the Uesugi era, Hobara Castle is thought to have been positioned as an important strategic point on the road connecting Aizu and Yonezawa.
Edo Period: From Branch Castle of the Uesugi Clan’s Yonezawa Domain to Abandonment
The Era of the Oishi Clan
In the Battle of Sekigahara in 1600 (Keicho 5), the Uesugi clan sided with the Western Army. After the war, their domain was reduced from 1.2 million koku in Aizu to 300,000 koku in Yonezawa. However, the Hobara area remained part of the Uesugi clan’s Yonezawa Domain.
In the early Edo period, the Oishi clan, a senior retainer of the Uesugi clan, was appointed as the lord of Hobara Castle. The Oishi clan was a prominent family of hereditary vassals of the Uesugi clan, and they governed the surrounding area from Hobara Castle.
Ogoshi Kiyomichi and the Abandonment of the Castle
In 1636 (Kanei 13), Ogoshi Kiyomichi was dispatched as the castle lord of Hobara Castle, replacing the Oishi clan. It is said that Hobara Castle was abandoned at this time. Due to the Edo shogunate’s “One Castle Per Province” decree, each domain was required to abolish castles other than its main castle, and it is believed that Hobara Castle was abandoned under this policy.
After the castle’s abandonment, a jinya (fortified residence) was established in Hobara, and it continued to function as an outpost of the Yonezawa Domain. The current name of Jinya-dori (Jinya Street) originates from the Hobara Jinya of this period.
Hobara Jinya (fortified residence) of the Shirakawa Domain
In 1742 (Kanpo 2) during the mid-Edo period, the Hobara Jinya was built by Matsudaira Sadakata, the lord of the Shirakawa Domain. This fortified residence was established by the Shirakawa Domain to govern the 17 villages of the Hobara area, and continued to function as a fortified residence for both the Shirakawa and Tanagura Domains even after the Abe clan took over. This Hobara Jinya was located in a different place from the Hobara Castle ruins (near the current Hobara Central Community Center in Date City).
Structure and Layout of Hobara Castle
Hobara Castle was built as a flatland castle, and it is believed that defensive structures were arranged utilizing the surrounding terrain.
Honmaru (Main Enclosure)
The Honmaru is estimated to have been located near the current Nakano Hospital (Nakano Clinic). Because it was a flatland castle, there were no large structures such as stone walls or a keep; it is thought to have been defended by earthworks and moats.
Moat and Reservoir
There was a large moat on the north side of the Honmaru, called “Motoki Reservoir.” This reservoir remained until recently, but has now been filled in. It is believed that the reservoir served not only as a defensive moat but also as a reservoir for agricultural water.
Town Layout
A castle town formed around Hobara Castle, forming the basis of the current Hobara town center. Place names reflecting the Edo period town layout, such as Jinya-dori (Jinya Street), still remain today.
