Hataya Castle (Yamagata Prefecture) Complete Guide: Visiting the Battlefield of the Keicho Dewa Campaign
Located in Yamabe Town, Higashimurayama District, Yamagata Prefecture, Hataya Castle is a historical mountain castle that was the stage of the Keicho Dewa Campaign, also known as the “Sekigahara of Tohoku.” Built on the summit of Mt. Tateyama at an altitude of 549m, this castle still bears the memory of the fierce battle in which a mere few hundred soldiers faced off against a massive Uesugi army of 20,000 led by Naoe Kanetsugu. This article comprehensively introduces information useful for visiting Hataya Castle, from its historical background and castle structure to its highlights and access methods.
Historical Background of Hataya Castle
As an Important Branch Castle of Yamagata Castle
Hataya Castle played an important role from the Sengoku period to the early Edo period as one of Yamagata Castle’s branch castles. Located near the border between the Murayama and Okitama regions, it functioned as a frontline castle for the Mogami clan, lords of Yamagata Castle, to defend against the Date and Uesugi clans, who ruled the Okitama region. This castle, built along the Kitsunegoshi Road (present-day Prefectural Road 17), was a strategically important base controlling a crucial transportation hub connecting Uesugi territory to Yamagata. The Mogami clan appointed their influential retainer, Eguchi Gohei Mitsukiyo, as the castle lord to prepare for threats from the south.
Construction Date and Lord
While there are various theories regarding the exact construction date of Hataya Castle, it is believed to have been fully developed in the early Keicho era (1596-1615). Eguchi Gohei Mitsukiyo, who served as the castle lord, was a well-known and respected retainer of the Mogami clan, entrusted with the defense of this area.
Eguchi Mitsukiyo was a warrior who valued “justice” as a Mogami samurai, and he would later demonstrate his loyalty with his life during the Keicho Dewa Campaign.
The Keicho Dewa Campaign and the Battle of Hataya Castle
In 1600 (Keicho 5), the Keicho Dewa Campaign, which erupted in the Tohoku region at the same time as the Battle of Sekigahara, was a large-scale battle sometimes called the “Sekigahara of Tohoku.” Hataya Castle became the site of the first fierce battle in this conflict.
When the Uesugi army, led by Naoe Kanetsugu, with approximately 20,000 men, began its invasion of Yamagata, Hataya Castle became a target of attack as a prelude to the Battle of Hasedo Castle. The castle lord, Eguchi Gohei Mitsukiyo, faced the overwhelmingly larger army with only a few hundred men, engaging in a fierce battle.
The Mogami army fought bravely, but the difference in troop numbers was insurmountable. After a fierce battle, Eguchi Mitsukiyo was killed in action, and Hataya Castle fell. The valiant efforts of the Mogami samurai in this battle have been passed down through generations as a tale of bravery.
Hataya Castle After its Fall
After the Keicho Dewa Campaign, Hataya Castle was abandoned. However, the castle ruins still retain excellent examples of the castle-building techniques of the Mogami region at the time, making it a valuable historical site that conveys the appearance of a mountain castle from the Sengoku period. It is designated as a historical site by Yamabe Town.
Hataya Castle’s Layout and Structure
Utilization of Location and Topography
Hataya Castle’s main enclosure is located on the summit (elevation 549m) of “Tateyama,” which is situated northwest of Higashikuromoriyama. This mountain, towering north of the Hataya settlement, was an excellent defensive base with a panoramic view of the surrounding area.
Maximizing its characteristics as a mountain castle, a defensive system utilizing the steep terrain was constructed. The main enclosure on the summit is relatively small, but its layout is characterized by its skillful use of the surrounding ridges and valleys.
Structure of the Main Enclosure
The main enclosure near the summit of Tateyama is compact but sturdily built. The main enclosure was long and narrow from east to west, with various enclosures featuring dry moats at different points.
Below the main enclosure to the west, a double dry moat was constructed, which was a crucial element of Hataya Castle’s defensive system. This double dry moat effectively prevented enemy advances.
Large-Scale Dry Moat System
The most distinctive feature of Hataya Castle is its large-scale dry moat system. Multiple dry moats were positioned within the castle grounds, each serving a different defensive function.
Large Dry Moat on the East
In the valley leading to the Yanazawa settlement to the east, there is a large dry moat built in a U-shape. This dry moat was an important defensive line to prevent incursions from the east. Its large scale speaks to the advanced civil engineering technology of the time.
Triple Dry Moat on the West
A triple dry moat was constructed on the ridge west of the main enclosure. These massive triple dry moats are located quite far from the main enclosure and boast an impressive scale that overwhelms visitors. It’s clear that they formed multiple defensive lines to prepare for attacks from the west.
These dry moats are particularly impressive remains within the Hataya Castle layout and serve as valuable resources for learning about the defensive techniques of mountain castles during the Sengoku period.
Earthworks and Enclosure Arrangement
Several enclosures are arranged around the main enclosure, each demarcated by earthworks. The earthworks are well-preserved in places, allowing visitors to appreciate the scale of the castle at the time.
The arrangement of the enclosures is skillfully designed to follow the terrain, demonstrating a design philosophy that maximized the limited mountaintop space. Each enclosure offers a panoramic view of the surrounding terrain, indicating the emphasis on surveillance and defensive functions.
Highlights of Hataya Castle
View from the Main Enclosure
From the main enclosure, at an altitude of 549m, you can enjoy a panoramic view of the Murayama region. On a clear day, you can see the Yamagata Basin and the surrounding mountains, giving you a real sense of the castle’s strategic location in monitoring important transportation routes.
The Impressive Triple Dry Moat
Proceeding west from the main enclosure, you reach the massive triple dry moat, the greatest highlight of Hataya Castle. This dry moat is large in both depth and width, a relic that allows you to experience the scale of civil engineering during the Sengoku period.
The triple dry moat was designed to gradually halt enemy advances, demonstrating the high level of castle-building technology of the Mogami clan. Since it is located quite far from the main enclosure, it is recommended to plan your visit with ample time.
The Large U-Shaped Dry Moat on the East
The large U-shaped dry moat built in the valley leading towards Yanazawa is also an important highlight of Hataya Castle. This dry moat cleverly utilizes the terrain, allowing you to observe a defensive system that integrates natural valley topography with artificial civil engineering.
Double Moat
The double moat below the west side of the main enclosure is a relatively well-preserved and clearly identifiable structure. The moat was dug to cut across the ridge, effectively preventing enemy soldiers from moving laterally.

Choshoji Temple is located right next to the Hataya Castle ruins. This temple has a close relationship with the castle ruins and offers a glimpse into the former castle town.
