Complete Guide to Tara Castle (Gifu Prefecture) | The Legend of Akechi Mitsuhide’s Birthplace and the History of the Takagi Three Families’ Camp
What is Tara Castle?
Tara Castle (Tara-jo) is a historical castle site located in the Tara district of Kamiishizu-cho, Ogaki City, Gifu Prefecture. This area is situated on a plateau south of Sekigahara, on the west bank of the Makita River, and was once a crucial transportation hub through which the Ise Highway passed. Currently, the name Tara Castle has multiple meanings, referring to both the castle site believed to have existed during the Sengoku period and the site of the Takagi Three Families’ camp built after the Battle of Sekigahara.
In particular, the site of the West Takagi Family’s camp was designated a National Historic Site on October 6, 2014, and occupies an important position in the history of Japanese castles. Furthermore, this area is also traditionally considered one of the birthplaces of Akechi Mitsuhide, making it a place of multifaceted appeal for history enthusiasts.
Historical Background of Tara Castle
Tara Castle in the Sengoku Period
There are various theories regarding the exact location and construction period of Tara Castle in the Sengoku period. It is believed that Seki Kazumasa, who owned this land before the Battle of Sekigahara, built Tara (or Yoshi) Castle, and the construction period is said to be either the Tensho or Keicho era.
There are 5-6 locations around Kamiishizu-cho that are thought to be castle ruins, and even today, the exact location of “Tara Castle” has not been identified. In 2019, a survey by Nakai Hitoshi confirmed that Jogahira Castle was a mountain castle, and this is also considered one of the candidate sites for Tara Castle.
Legend of Akechi Mitsuhide’s Birthplace
Tara Castle is traditionally believed to be one of the birthplaces of Akechi Mitsuhide. While there are several candidate locations throughout Japan for Akechi Mitsuhide’s birthplace, the Tara district of Kamiishizu-cho, Ogaki City, Gifu Prefecture is one of them.
In the local area, the “Tara History Enthusiasts’ Association” is leading community development efforts that utilize this legend, including the erection of banners proclaiming “Birthplace of Akechi Mitsuhide.” Active participation by local residents, such as holding history lectures, is a key characteristic.
The Battle of Sekigahara and the Entry of the Takagi Clan
In 1600, the Takagi clan was granted the land of Tara-go for their military achievements in the Battle of Sekigahara. Takagi Sadatoshi (West Branch) received 2,300 koku, Takagi Sadatomo (East Branch) 1,000 koku, and Takagi Sadatoshi (North Branch) 1,000 koku, and they entered the territory the following year, 1601.
This resulted in a three-branch system for the Takagi clan: the main West Takagi branch, and the branch East and North Takagi branches, each establishing their own fortified residences. The existence of these “Three Takagi Branches” is a significant feature in the history of Tara Castle.
Takagi Family Encampment Sites
West Takagi Family Encampment Site (National Historic Site)
The West Takagi Family Encampment Site is the largest of the three Takagi families’ encampments and was designated a National Historic Site in 2014. Located on a hill, it is characterized by its towering stone walls. The Nakatani River and Karyuya River flow behind it, forming a natural fortress.
The old Ise Highway passed in front of the encampment, making it a crucial transportation hub connecting Sekigahara and the Ise region. Even today, the stone walls and main gate, remnants from the Edo period, remain well-preserved, allowing us to imagine the encampment’s appearance at the time.
East Takagi Family Encampment Site
The East Takagi Family Encampment Site still retains a storehouse. This storehouse is a valuable relic among the three Takagi families’ remains, and is characterized by the omission of the namako-kabe (sea cucumber-shaped wall) on the wall not facing the Ise West Highway.
The Higashi-Takagi family held a fiefdom of 1,000 koku, making them the second largest after the Nishi-Takagi family. The layout of their encampment was designed considering its relationship to the Nishi-Takagi family’s encampment, and the ingenuity of this arrangement is clearly evident when viewing the map of the three families’ residences.
Kita-Takagi Family Encampment Site
The Kita-Takagi family also received a fiefdom of 1,000 koku and established their own encampment. Although the smallest of the three families, they played an important role in the overall governance system of the Takagi clan.
While each of the three Takagi families had their own independent encampments, they cooperated in governing Tara-go. This three-family system was maintained throughout the Edo period and continued until the Meiji Restoration.
Highlights of Tara Castle
Stone Walls of the Nishi-Takagi Family Encampment
The greatest highlight of the Nishi-Takagi family encampment is the magnificent stone walls built on a hilltop. The walls, built to overlook the area from a high vantage point, combine defensiveness and dignity, overwhelming visitors.
The stone walls were constructed using techniques from the early Edo period, demonstrating the high level of stonework technology at the time. They remain in excellent condition and are easily accessible thanks to ongoing restoration work.
Uzumemon Stone Wall
The stone wall of the Uzumemon (buried gate) is also an important historical structure. The Uzumemon was the back entrance to the jinya (fortified residence) and also served as an escape route in emergencies. The stone walls in this section feature ingenious defensive features, making them valuable resources for learning about castle construction techniques.
Nishitakagi Family Main Gate
The main gate of the Nishitakagi family jinya was built in 1852 (Kaei 5). Facing the old Ise Highway, this gate presents a dignified appearance as the main entrance to the jinya.
The main gate is a valuable historical structure that conveys the beauty of wooden architecture and is important for understanding the architectural style of the late Edo period. It remains in excellent condition and is an important component of the nationally designated historical site.
Main House and Buildings
The remains of buildings, including the main house, are still preserved at the site of the jinya (fortified residence). These buildings clearly exhibit the characteristics of samurai residences from the Edo period and are valuable resources for understanding the lifestyle of that time.
The layout and structure of the buildings reveal both the functionality of the jinya and the awareness of respecting the status of the daimyo (feudal lord) family.
Relationship with the Old Ise Road
Tara Castle was built facing the old Ise Road. This road was an important transportation route connecting Sekigahara and the Ise area, and there was a lot of traffic of people and goods.
The placement of the jinya along the road served not only practical reasons such as traffic monitoring and tax collection, but also as a display of authority. Traces of the old road can still be followed today, making it an enjoyable historical walk.
Geographical Characteristics of Tara Castle
Makita River and Natural Fortress
The Makita River flows in front of Tara Castle, serving as a natural moat. The Makita River is an important river flowing south from Sekigahara and plays a significant role in shaping the topography of this region.
Behind it lies a valley through which the Nakatani River and Karyuya River, tributaries of the Makita River, flow, forming a natural fortress. The encampment, built on a plateau, enjoyed a strong position, protected on both the front and rear by the river.
Location in relation to Sekigahara
Tara Castle is located approximately 10 kilometers south of Sekigahara. After the Battle of Sekigahara, this area was recognized as strategically important, and the Takagi clan was stationed there.
Its location controlled the route from Sekigahara to the Ise region, making it a militarily and economically important base. This location is thought to be one of the reasons why it was chosen as the Takagi clan’s territory.
Current status and maintenance of Tara Castle
National Historic Site designation and preservation activities
Since its designation as a National Historic Site in 2014, a full-scale preservation and maintenance project has been underway at the site of the Nishitakagi family encampment. The restoration of the stone walls, the protection of the remains, and the development of viewing paths have been systematically implemented, creating an environment where visitors can safely learn about history.
The local government, Ogaki City, has positioned this historical site as an important cultural asset of the region and has indicated its intention to utilize it as a tourist resource.
Collaboration with the Kamiishizu Local History Museum
To gain a deeper understanding of the history of Tara Castle, a visit to the Kamiishizu Local History Museum is recommended. The museum houses materials related to the Takagi Three Families and exhibits illustrating the history of Tara Castle, and a visit before or after visiting the site will deepen your understanding.
The museum also regularly holds special exhibitions, showcasing the results of local historical research.
Local Utilization and Initiatives
In the Tara district, the “Tara History Enthusiasts’ Association” is leading community development efforts that leverage the history of Tara Castle. They are actively promoting the legend of Akechi Mitsuhide’s birthplace, setting up banners, and holding history lectures.
These initiatives contribute to the formation of local residents’ identity and serve as a prime example of regional revitalization through history.

Around Tara Castle, there are numerous historical sites related to the three Takagi families, including the storehouse at the site of the East Takagi family’s encampment and the site of the North Takagi family’s encampment. If you have time, a “Takagi Three Families Tour” including these sites will provide a more comprehensive understanding of the region’s history.
Visiting other potential sites for Tara Castle, such as Jogahira Castle (confirmed in 2019), is also an interesting experience.
Historical Significance of Tara Castle
An Example of Small Daimyo Governance in the Edo Period
The encampment sites of the three Takagi families are valuable examples of the form of governance of small daimyo during the Edo period. Despite having small fiefs ranging from 1,000 to 2,300 koku, the Takagi clan established independent encampments and governed the region, which is important for understanding the Edo shogunate’s governing system.
The system of cooperation among the three families while maintaining independence is a unique form of regional rule by a family and has attracted historical attention. ### Rewards and Punishments After the Battle of Sekigahara
The Takagi clan’s granting of Tara-go was a reward for their contributions to the Tokugawa side in the Battle of Sekigahara. This is one concrete example illustrating the impact the Battle of Sekigahara had on the distribution of territories throughout Japan.
The history of Tara Castle reveals the historical process of the treatment of samurai and the redistribution of territories during the transition from the Sengoku period to the Edo period.
Importance in Regional History
Tara Castle and the three Takagi families hold a significant position in the history of Mino Province, particularly the western Mino region. Located near the site of the decisive Battle of Sekigahara and situated at a crucial transportation hub on the Ise Highway, the history of this region is closely intertwined with the history of Japan as a whole.
Including the legend of Akechi Mitsuhide’s birthplace, Tara Castle is an important element in shaping the region’s identity.
Summary
Tara Castle in Kamiishizu-cho, Ogaki City, Gifu Prefecture, is a historically significant site with two distinct aspects: the remains of a castle from the Sengoku period and the remains of the Takagi family’s encampment from the Edo period. In particular, the remains of the West Takagi family’s encampment are designated as a national historic site, and the magnificent stone walls and main gate are remarkably well-preserved.
With its multi-layered history—including the legend of Akechi Mitsuhide’s birthplace, the Takagi family’s entry into the area as a reward after the Battle of Sekigahara, and the rule of the Takagi family throughout the Edo period—this site is a valuable place for learning about the history of Japanese castles and local history.
Currently, local residents continue their efforts to preserve and utilize the site, conveying the depth of its history and the charm of the region to visitors. Visiting in conjunction with sightseeing in Sekigahara will provide a more enriching historical experience.
Tara Castle is a historical site with a different kind of charm than famous castles with large keeps. By carefully tracing the historical traces etched into the stone walls and encampment remains, the image of the local community during the Edo period emerges. This is a place that I would definitely recommend visiting not only to history buffs, but also to anyone interested in local culture.
