Complete Guide to the History and Highlights of Hekida Castle (Nakano City, Nagano Prefecture) | The Full Picture of the Takanashi Clan’s Branch Castle
What is Hekida Castle?
Hekida Castle is a Sengoku period mountain castle located in Hekida, Nakano City, Nagano Prefecture. Built on a river terrace on the right bank of the Chikuma River, at an altitude of approximately 480 meters, the castle’s relative height difference is about 140 meters. Currently, the castle ruins remain around Nagaoka Shrine, and it is known as an important border castle in Shinano Province.
As a strategic point located between the Zenkoji Plain and Iiyama Castle, it played a crucial role in the conflicts of northern Shinano, including the Battle of Kawanakajima. It was developed as a branch castle of the Takanashi clan, and the Yamada clan, vassals of the Takanashi clan, served as its lords.
History of Hekida Castle
Establishment as a Takanashi Clan Branch Castle
Hekida Castle was a branch castle built by the Takanashi clan, a powerful local family in northern Shinano. The Takanashi clan was based at Nakano-Kodate and maintained their sphere of influence by placing several branch castles in the surrounding area. Kabeta Castle was one of these branch castles, a crucial stronghold responsible for the defense of the east bank of the Chikuma River.
The castle was ruled by the Yamada clan, vassals of the Takanashi clan, with figures such as Yamada Hida-no-kami (Yamada Da-no-kami) and Yamada Saemon-no-jo recorded in historical records. The Yamada clan governed the Kabeta area and played a vital role in supporting the Takanashi clan’s military power.
The Battle of Kawanakajima and the Uesugi Clan’s Supply Base
In the early stages of the Battle of Kawanakajima, Kabeta Castle was used as a supply base by the Uesugi clan (Nagao clan). In the conflict between Takeda Shingen and Uesugi Kenshin over the Zenkoji Plain, northern Shinano became the front line between the two forces, and Kabeta Castle’s strategic importance increased.
With the Chikuma River providing a natural defensive line behind it, Kabeta Castle possessed ideal location conditions for the accumulation of supplies and the stationing of troops. For the Uesugi clan, Kabeta Castle was an indispensable staging point when advancing from the Iiyama area towards the Zenkoji Plain.
Surrender to the Takeda Clan in 1566
In 1566, when Takeda Shingen launched a large-scale invasion of northern Shinano, the situation changed dramatically. At this time, the castle lords, Yamada Hida-no-kami and Yamada Saemon-no-jo, chose to surrender to the Takeda clan.
This surrender symbolized the decline of the Takanashi clan’s power and the advancement of the Takeda clan’s control over northern Shinano. The Takanashi clan lost their base, Nakano-kodate, and fled to the Uesugi clan. Kabeta Castle also came under the control of the Takeda clan and is thought to have changed its role in subsequent history.
Subsequent History
Although there are few detailed records of how Kabeta Castle was used after its surrender to the Takeda clan, it is presumed to have functioned as one of the Takeda clan’s bases in their administration of northern Shinano. After the fall of the Takeda clan in 1582, it is believed to have been ruled by various generals under the Uesugi and Oda clans before finally being abandoned.
Investigations by the Nagano Prefectural Buried Cultural Properties Center did not uncover any clear remains or artifacts related to medieval or early modern mountain castles. The flat area initially thought to be related to a medieval mountain castle has been confirmed to be farmland created later for cultivating mulberry and fruit trees. This indicates that the castle site was used as agricultural land over a long period of time.
Structure and Layout of Kabeta Castle
Location and Topography
Kabeta Castle was built on a hill on a river terrace on the east bank of the Chikuma River. The Chikuma River flows in a large loop around the castle hill, functioning as a natural defensive line. Located at an altitude of approximately 480 meters, with a relative height difference of about 140 meters, the castle offered an excellent vantage point for observation, overlooking the vast Zenkoji Plain.
With the Chikuma River, a major river, at its rear, the castle’s defenses against attacks from the west were enhanced, and it is believed that the castle also benefited from convenient water transport for goods. This topographical advantage was one of the factors that made Kabeta Castle an important military base.
Arrangement of Enclosures and Baileys
Kabeta Castle’s layout consists of multiple enclosures (baileys) running north-south. A series of enclosures, arranged in stages around the main enclosure, formed a defensive line.
The main enclosure, located at the highest point of the castle, is presumed to have served as the lord’s residence and command post. Secondary enclosures, such as the second and third baileys, were arranged around it, forming a multi-layered defensive structure. Each enclosure was demarcated by earthen ramparts, which are thought to have further enhanced its defensive capabilities.
Moats and Earthworks
As a mountain castle, Kabeta Castle featured moats and earthworks as important defensive structures. The moats were excavated to cut across the ridge, serving to prevent enemy incursions. It is presumed that multiple moats were strategically placed to defend against attacks from the north and south.
The earthworks were built along the edges of the baileys and functioned as defensive walls. They protected against enemy arrows and firearms, and also made it difficult to see inside the baileys. Even today, some remnants of the earthworks can be seen, offering a glimpse into the castle’s structure in its heyday.
Relationship between Nagaoka Shrine and the Castle Ruins
Currently, Nagaoka Shrine stands in the center of the Kabeta Castle ruins. Traces of the castle remain within the shrine grounds and surrounding area, serving as landmarks when visiting the castle remains.
The construction of shrines on castle sites is a phenomenon frequently seen in the history of Japanese castles. One aspect of the castle’s preservation is that, after its abandonment, the land was transformed into a place of local worship. Nagaoka Shrine, too, can be considered an important presence that conveys the history of Kabeta Castle to the present day.
Highlights of Kabeta Castle
View from the River Terrace
The greatest highlight of Kabeta Castle is the view from the river terrace. The scenery of the Zenkoji Plain viewed from an altitude of approximately 480 meters is breathtaking, and it is likely that the castle lords of the Sengoku period strategized while gazing at this view.
On a clear day, you can even see the mountains of the Northern Alps in the distance. The landscape, woven from the flow of the Chikuma River, the expanse of the plains, and the surrounding mountains, clearly represents the geographical characteristics of Shinano Province. This view makes it clear why Kabeta Castle was such an important military base.
Remaining Earthworks and Enclosures
Although many remains of Kabeta Castle have been lost over the long years, careful observation can reveal traces of earthworks and enclosures. In particular, around Nagaoka Shrine, traces of artificial flat surfaces and earthen mounds remain, offering a glimpse into the castle’s structure.
For castle enthusiasts, discerning these subtle topographical changes is the essence of exploring castle ruins. Within the vegetated slopes and terraces, you can find traces of Sengoku period castle construction techniques.
The Relationship Between the Chikuma River and the Castle Ruins
When visiting Kabeta Castle, pay attention to its relationship with the Chikuma River. The way the Chikuma River flows, making a large detour around the castle hill, demonstrates the ingenuity of the medieval castle’s location selection, skillfully utilizing the natural terrain.
Experiencing both the view looking up at the castle ruins from the riverbank and the view looking down at the river from the castle ruins will allow you to gain a deeper understanding of Kabeta Castle’s strategic value. You will surely appreciate the importance of the Chikuma River in both water transport and defense.

Kabeta Castle and the Sengoku History of Shinano
Connection to the Battle of Kawanakajima
The Battle of Kawanakajima was a series of battles fought between Takeda Shingen and Uesugi Kenshin from 1553 to 1564 over control of northern Shinano. Kabeta Castle functioned as a supply base for the Uesugi clan in the early stages of this conflict.
In the struggle between the two powerful clans for control of the Zenkoji Plain, Kabeta Castle, located on the east bank of the Chikuma River, was a crucial supply base for the Uesugi clan. It held strategic value as a relay point when advancing from Iiyama to the Zenkoji Plain, and as a place to accumulate supplies.
Takeda Clan’s Invasion of Northern Shinano
The surrender to the Takeda clan in 1566 indicates a stage close to the completion of Takeda Shingen’s control over northern Shinano. During this period, the Takeda clan was gaining control of almost all of northern Shinano, excluding Iiyama Castle.
The surrender of Yamada Hida-no-kami and Yamada Saemon-no-jo symbolized the final collapse of the Takanashi clan’s power. The Takanashi clan fled to the Uesugi clan and continued to exist as vassals of the Uesugi clan thereafter.
Regional Governance Structure in the Sengoku Period
