What is Takigawa Castle?: A Castle in Omi Associated with Takigawa Kazumasu, One of the Four Heavenly Kings of Oda
Takigawa Castle is a Sengoku period castle site located in Ichino, Koga-cho, Koga City, Shiga Prefecture. Also known as “Gotanda Castle,” it is known as a flatland castle (hill castle) built on the hilly area on the south bank of the Ichino River.
The most distinctive feature of this castle is its deep connection to Takigawa Kazumasu, who served as a retainer of Oda Nobunaga and is counted as one of the “Four Heavenly Kings of Oda.” It is said that Takigawa Kazumasu once resided here, or that this was his birthplace, and it played an important role as the base of the Takigawa clan in the Koga region.
Currently, it is a designated historical site of Koga City, and remains such as earthworks and moats are well preserved. Located south of Ichino-dera Temple, a representative ancient temple of the Koga region, and built across the Ichino River, Takigawa Castle’s location showcases the skillful use of natural terrain and the castle-building techniques of the Sengoku period.
History of Takigawa Castle: The Footsteps of the Takigawa Clan and Takigawa Kazumasu
The Origins of the Takigawa Clan and the Castle
Takigawa Castle was built by the Takigawa clan, who ruled the Ichino area of Koga County in Omi Province. The Takigawa clan was one of the 53 families of Koga and was a local powerful family deeply rooted in the region since ancient times. While there are no clear records of the castle’s construction date, it is believed to have been built sometime between the early and mid-Sengoku period.
The castle’s highly defensible layout, utilizing the natural moat of the Ichino River and the hilly terrain to the south, demonstrates the unique castle-building techniques of the local samurai of the Koga region. The Takigawa clan, as members of the Koga clan, survived the turbulent Sengoku period, sometimes as an independent force and sometimes as subordinates to powerful daimyo.
The Relationship Between Takigawa Kazumasu and Takigawa Castle
Takigawa Kazumasu (1525-1586) was a Sengoku period warlord who served Oda Nobunaga and achieved numerous military successes. He was particularly known as a master of firearms, and played a crucial role in Nobunaga’s unification of Japan, including the conquest of Ise Province, the suppression of the Nagashima Ikko-ikki rebellion, and his appointment as Kanto Kanrei (governor of the Kanto region), where he was entrusted with Kozuke Province (present-day Gunma Prefecture).
There are mainly two theories regarding the relationship between Takigawa Kazumasu and Takigawa Castle.
Birthplace Theory: This theory suggests that Takigawa Kazumasu was born at Takigawa Castle in Ichino. There is a tradition that he was born at this castle, the base of the Takigawa clan, and later served the Oda family.
Temporary Residence Theory: This theory suggests that after Takigawa Kazumasu served Oda Nobunaga, he temporarily used this castle as his residence for the purpose of conquering Omi Province and governing the Koga region. It has been suggested that as Nobunaga’s power expanded, he may have utilized his hometown castle as a base.
While both theories lack definitive historical evidence, it is undeniable that this was the Takigawa clan’s base, and its connection to Kazumasu is deeply rooted in local traditions.
From the Azuchi-Toyotomi Period to the Edo Period
After Oda Nobunaga’s pacification of Omi Province, the Koga region came under his direct control. Takigawa Kazumasu himself became the lord of Ise Nagashima Castle, and later, as the Kanto Kanrei (governor of the Kanto region), the lord of Kozuke Maebashi Castle (Maebashi Castle). It is believed that he did not permanently reside at Takigawa Castle.
After the Honnoji Incident (1582), Kazumasu was defeated by the Hojo clan in the Battle of Kannagawa and forced to withdraw from the Kanto region. Afterward, he served Toyotomi Hideyoshi, but was unable to regain his former power.
In the Edo period, Takigawa Castle was abandoned and remained only as a castle ruin in the local memory. However, the remains such as earthworks and moats were preserved without destruction, and it remains a valuable historical site that conveys the structure of a Sengoku period castle.
Structure and Layout of Takigawa Castle: A Defensive System Utilizing the Topography
Location and Utilization of Topography
Takigawa Castle was built on the tip of a ridge that branches off from the north on the south bank of the Ichinogawa River. Although the elevation is not particularly high, the Ichinogawa River served as a natural moat to strengthen the northern defense, while the east, west, and south sides were protected by earthworks and moats.
The Ichinogawa River flows to the north of the castle, and this river functioned as a natural moat. Ichino-dera Temple was located on the opposite bank of the river, and it is said that a Takigawa branch castle was also situated there. This layout suggests that the Takigawa clan controlled both banks of the Ichinogawa River, establishing control over a crucial point for water transport and transportation.
Major Remains
Main Enclosure: A rampart extending east-west runs through the center of the castle. Ramparts are visible on both the north and south sides, with the southern rampart being particularly important for defense. The main enclosure area has been leveled, providing a flat area for building structures.
Moat: A large moat is located on the south side, serving as an important defensive structure to prevent intrusion from the ridge. This moat is still clearly visible today, and its depth and width indicate considerable defensive capability.
Earthwork: Earthworks remain in various locations within the castle. The ramparts surrounding the main enclosure are particularly high, suggesting they served to prevent enemy intrusion and also obscure the view of the interior from the outside.
Leveled Area: Multiple leveled areas can be seen on the lower west side. These structures functioned as outer baileys, forming a multi-layered defensive line. It is also presumed they were used as residences for retainers and garrisons for soldiers.
Related Castles
Several related castles exist around Takigawa Castle, indicating the sphere of influence of the Takigawa clan.
Takigawa West Castle: A subsidiary castle located on the ridge west of Takigawa Castle. It was responsible for the western defense of Takigawa Castle and served as one of the key bases for controlling the Ichino region in coordination with the main castle.
Takigawa Branch Castle: A castle believed to have been located north of the Ichino River. While detailed remains are unknown, it is thought to have been intended for defense and surveillance from the opposite bank of the river.
These castles, together, formed a network of castles protecting the Takigawa clan’s territory.
Highlights of Takigawa Castle: Points to Note When Visiting the Castle Ruins
Well-Preserved Earthworks
The greatest highlight of Takigawa Castle is its well-preserved earthworks. The earthen ramparts surrounding the main enclosure are quite high, allowing you to directly experience the castle-building techniques of the Sengoku period. Walking along the ramparts allows you to imagine how the castle’s defenders defended the castle at that time.
Deciphering the castle’s layout from the shape and arrangement of the ramparts is also enjoyable. Paying particular attention to the differences in height and thickness between the north and south sides reveals defensive priorities and anticipated attack directions.
Clear Moat
The large moat on the south side is particularly impressive among the remains of Takigawa Castle. The moat, which deeply cuts through the ridge, still retains its depth and width, clearly demonstrating its crucial role in the castle’s defense system.
Standing on both sides of the moat and comparing them, you can appreciate the difference in elevation and the steepness of the cliffs, realizing how difficult it would have been to cross and attack. It is a highly educational example of Sengoku period castle defense techniques.
View of the Ichinogawa River
Looking north from the castle ruins, you can see the flow of the Ichinogawa River. This is an excellent spot to visually understand how the river functioned as a natural moat. The temple buildings of Ichinoji Temple are visible on the opposite bank, and the relative positions of the castle and temple allow you to imagine the landscape of the Ichinogawa area in the Middle Ages.
Strolling through the castle ruins while listening to the sound of the flowing river will allow you to feel the atmosphere of the Sengoku period more deeply.

Takigawa Kazumasu was a Sengoku period samurai born in 1525 (Daiei 5) and died in 1586 (Tensho 14). He served Oda Nobunaga and was counted as one of the “Four Heavenly Kings of Oda” (the others are often said to be Shibata Katsuie, Niwa Nagahide, and Akechi Mitsuhide).

The Fifty-Three Families of Koga and the Takigawa Clan
The Fifty-Three Families of Koga is a collective term for local powerful families that held sway in Koga County. While it is believed that there were actually more families than fifty-three, the most representative families were referred to as the “Fifty-Three Families.”
The Takigawa clan was one of them, based in the Ichino region. The Koga clan was highly independent and tended to make decisions through a council system, not necessarily following a single powerful leader.
However, amidst the turmoil of the Sengoku period, many clans were subservient to powerful daimyo such as the Rokkaku and Oda clans, and some, like Takigawa Kazumasu, even served individual powerful daimyo.
The Position of Omi Province in Sengoku History
Omi Province (present-day Shiga Prefecture), being close to Kyoto, played a crucial role in the Sengoku period as a key point for east-west transportation. The Koga region, in particular, was strategically important as it lay on the route connecting Ise and Kyoto.
Takigawa Castle, though not large in scale, functioned as a base for regional control and supported the Takigawa clan’s power base. After Oda Nobunaga’s conquest of Omi, it is believed to have been incorporated as part of Nobunaga’s system of rule.
