Takami Castle (Tanba City, Hyogo Prefecture) Complete Guide: From a Fortress of the Nanboku-cho Period to the Conquest by Akechi Mitsuhide
What is Takami Castle?
Takami Castle is a medieval mountain castle located in Kashiwabara-cho, Tanba City, Hyogo Prefecture. Built on the summit of Mount Takami, at an altitude of 485 meters, it is a natural fortress. Also known as “Sano Castle,” it functioned as an important military base in the Tanba region from the Nanboku-cho period to the Sengoku period.
Located in a steep mountainous area, this castle straddles the former Kashiwabara-cho and Hikami-cho, and is known as an impregnable mountain castle that takes advantage of the rugged terrain with a relative height of approximately 380 meters. Currently preserved as a historical site by Tanba City, and with well-maintained hiking trails, it is a popular spot for history enthusiasts and castle fans.
History of Takami Castle
Nanboku-cho Period: Construction by Niki Yorishige
The construction of Takami Castle dates back to the second year of the Karyaku era (1327). It was built by Niki Yorishige, a retainer of Ashikaga Takauji and appointed governor of Tanba Province. Niki Yorishige was a warrior who played an active role during the turbulent Nanboku-cho period as a senior retainer of the Ashikaga clan, and he established this castle as a base for governing Tanba Province.
The 32nd volume of the *Taiheiki* also mentions Takami Castle. Records show that when Yamana Tokiuji and his son Moriuji invaded Kyoto from Tajima Province, the Niki clan, the governors of Tanba, holed up in this castle. This historical document indicates that Takami Castle was an important military base during the Nanboku-cho period.
The Niki clan maintained their power as governors of Tanba for a long time, but gradually lost influence as the Nanboku-cho period came to an end.
Muromachi Period: The Era of the Yamana and Hosokawa Clans
With the end of the Nanboku-cho period and the beginning of the Muromachi period, the rulers of Takami Castle changed hands. After the Niki clan, the position of Shugo (military governor) of Tanba Province passed to the Yamana clan, and then to the Hosokawa clan, with Takami Castle falling under the control of each respective power.
Especially during the Hosokawa clan’s rule, Tanba Province was considered a strategically important location close to Kyoto, and Takami Castle is thought to have played a key role in their control.
Sengoku Period: The Akai Clan’s Rule
With the arrival of the Sengoku period, Takami Castle came under the control of the local powerful Akai clan. The Akai clan were local lords who expanded their power in the Tanba region, and Takami Castle became the possession of Akai Kiyoshi, whose base was Ushiroya Castle.
After seizing Kuroi Castle, the stronghold of the related Ogino clan, the Akai clan further strengthened their power in the Tanba region. During this period, Takami Castle functioned as an important branch castle of the Akai clan, playing a role in protecting their sphere of influence in Tanba Province.
The Akai clan is known for producing Akai Naomasa, who was feared as the “Red Demon of Tanba,” and was a force that fiercely resisted Oda Nobunaga’s invasion of Tanba.
Tensho 7 (1579): Capture and Fall of Takami Castle by Akechi Mitsuhide
The biggest turning point in the history of Takami Castle came in Tensho 7 (1579). Akechi Mitsuhide, acting on orders from Oda Nobunaga, intensified his invasion of Tanba, and Takami Castle, where Akai Tadayoshi served as lord, became a target.
Akechi Mitsuhide’s retainer, Yomoda Masataka, commanded the attack on Takami Castle, and after a fierce battle, the castle fell. This fall significantly weakened the Akai clan’s power in Tanba.
Akechi Mitsuhide’s pacification of Tanba was an important part of Oda Nobunaga’s unification of Japan, and the capture of Takami Castle held significant importance within that strategy. While there are no clear records of how Takami Castle was used after its fall, it is believed to have been abandoned after the pacification of Tanba Province.
Structure and Layout of Takami Castle
Location and Topography
Takami Castle was built on Takami Castle Mountain, a 485-meter-high mountain located at the southwestern edge of Kashiwabara Town. Its steep terrain provided a natural stronghold, offering ideal defensive conditions that made enemy intrusion difficult.
From the summit, one could see the surrounding plains, serving as a surveillance function to detect enemy movements early. Furthermore, its location overlooking a key transportation hub in the Tanba region made it a strategically and militarily important point.
Arrangement of Enclosures
Because Takami Castle was built in a steep mountainous area, the areas where enclosures could be constructed were limited. Therefore, the castle was divided into four main sections, making maximum use of the terrain.
The main enclosure was located at the summit and functioned as the main keep. The main enclosure features four levels of flat land, each designed to function as a defensive line. It is presumed that the uppermost level served as the lord’s residence and command post, while the lower levels were used as soldiers’ quarters and supply storage.
Each enclosure is strategically positioned along ridges and valleys, creating a layout that allows for coordinated defense.
Defensive Structures
Takami Castle retains defensive structures typical of medieval mountain castles.
Earthworks were built around the enclosures, preventing enemy intrusion and serving as protective barriers against arrows and stones. Clear traces of these earthworks can still be seen in various places.
Stone walls are also visible in some areas, but these are more like stacks of natural stones rather than full-fledged stone walls. This indicates the castle’s early construction date and the difficulty of large-scale stone wall construction due to its mountainous terrain.
Defensive structures created by cutting into the terrain, such as horikiri (moats) and tatebori (vertical moats), can be seen, demonstrating ingenuity in preventing enemy incursions from the ridgeline.
Ascent Route
While it is believed that there were multiple ascent routes to the castle at the time, only a limited number of major routes can be confirmed today. The winding paths, utilizing the steep terrain, were designed to prevent large enemy armies from attacking all at once.
Highlights of Takami Castle
Remains of the Main Enclosure
The main enclosure at the mountaintop is the greatest highlight of Takami Castle. The four-tiered flat area remains clearly visible, allowing visitors to experience the structure of a medieval mountain castle. From the top tier, you can enjoy a panoramic view of Tanba city, and on clear days, a magnificent view stretches as far as Harima.
Remnants of earthworks remain around the main enclosure, allowing us to imagine the defensive system of the time.
Arrangement of the Enclosures
The arrangement of the enclosures along the ridge from the main enclosure is a valuable historical site for studying the layout of mountain castles. You can see firsthand how each enclosure coordinated and formed a defensive line.
Earthworks and Moats
The earthworks and moats remaining in various places are important historical remains that demonstrate medieval castle construction techniques. In particular, the moats blocking the ridge clearly show the ingenuity used to prevent enemy intrusion.
Panoramic View
The 360-degree panoramic view from the mountaintop is one of the greatest attractions of visiting Takami Castle. You can see the cityscape of Tanba, the surrounding mountains, and, on a clear day, even the Sea of Japan in the distance. This view truly makes you understand why Takami Castle was chosen as a strategically important military location.

Historical Significance of Takami Castle
Takami Castle is not merely a local mountain castle, but a fortress that embodies a crucial turning point in Japanese history.
During the Nanboku-chō period, it served as a base for the Ashikaga clan’s expansion; during the Muromachi period, it supported the rule of the shugo daimyo; and during the Sengoku period, it was a stage for the struggle between local powerful families and the Oda regime’s efforts to unify the country. Each era played a crucial role.
In particular, Akechi Mitsuhide’s conquest of Tanba was a vital part of Oda Nobunaga’s unification of Japan, and the fall of Takami Castle was a symbolic event in that process. Tracing the history of this castle allows us to understand the regional developments during the transition from the medieval to the early modern period.
Value in Castle Research
Takami Castle is a valuable historical site from the perspective of castle research.
As a mountain castle built relatively early, during the Nanboku-chō period, and used until the Sengoku period, it is a good example of the evolution of castle construction techniques. It is a typical example of a mountain castle built using civil engineering techniques before the widespread introduction of stone walls, and the arrangement of defensive structures such as earthworks and moats is textbook-worthy for medieval mountain castles.
Furthermore, the castle’s layout, which makes maximum use of the steep terrain, demonstrates ingenuity in castle construction techniques under limited conditions, allowing us to learn about the pursuit of practicality and defensiveness in castle architecture.
Efforts for Preservation and Utilization
Tamba City is working to preserve and utilize the Takami Castle ruins as a valuable cultural asset.
