Kirihata Castle is located in the northern bank area of the Yoshino River in the central part of Awa City. Several other castles from the same period, such as Imaichi Castle, Yamanokami Castle, and Kawato Castle, are scattered around the area. These castles formed part of a defense network built by the medieval lords of Awa Province for regional control.
The History of Kirihata Castle | Understanding the Sengoku Period in Awa Province
Background of Construction and the Situation in Awa Province
During the period when Kirihata Castle was built, Awa Province was under the rule of powerful warlords such as the Hosokawa and Miyoshi clans. Especially during the Sengoku period, the Miyoshi clan expanded their power from Awa Province to the Kinai region, boasting immense power and even being called “rulers of Japan.”
While there is a lack of reliable historical records regarding the builder and construction date of Kirihata Castle, and many details remain unknown, it is believed to be one of the castles built by local lords in Awa Province for the defense and control of their territories. Given its location near a strategic transportation hub on the north bank of the Yoshino River, it undoubtedly held military and economic importance.
Role and Function in the Sengoku Period
During the Sengoku period in Awa Province, the Miyoshi clan’s retainers and local lords constructed castles throughout the region, using them as bases for territorial management and military operations. It is presumed that Kirihata Castle, as one such castle, played the following roles:
- Center of Regional Control: The residence of the lord who governed the rural area around Kirihata in Ichiba-cho
- Military Surveillance: Functioning to monitor and control transportation routes in the Yoshino River basin
- Emergency Shelter: A place of refuge for the local population during times of war
Abandonment of the Castle and its Aftermath
During the Tensho era (1573-1592), Toyotomi Hideyoshi pacified Shikoku, and Chosokabe Motochika temporarily ruled the entire Shikoku region, including Awa Province. Later, when Hachisuka Iemasa entered Awa Province as its lord, a new governing system centered on Tokushima Castle was established.
In this process, it is believed that many medieval mountain castles, including Kirihata Castle, lost their military role and were abandoned. From the Edo period onward, the land was used for farming and forestry, and the remains have been preserved to this day.

Major Remains
Visiting the Kirihata Castle ruins reveals typical remains of a medieval castle, such as:
Enclosures (Kuruwa)
Several flat areas (kuruwa) remain in the central part of the castle. These were the locations of the lord’s residence, soldier encampments, and armories. A distinctive feature is the arrangement of the enclosures in a stepped pattern around the main enclosure, showcasing a typical layout for a medieval mountain castle.
Earthworks and Moats
Remnants of earthworks remain around the enclosures, functioning as defensive structures to prevent enemy intrusion. Moats blocking the ridges can also be observed, demonstrating efforts to enhance the castle’s defensibility.
Steep Slopes (Kirigishi)
Steep slopes created by carving into the natural terrain are also visible in various places. This effectively made it difficult for enemies to climb.
Excellent Views and Location
From the Kirihata Castle ruins, you can enjoy panoramic views of the Yoshino River basin and the city of Awa. This excellent view speaks to its importance as a military surveillance point. On clear days, you can enjoy the beautiful scenery of the mountains and plains of northern Tokushima Prefecture, making it a spot where you can enjoy both historical exploration and the charm of nature.
Relationship with Kirihata-ji Temple | Historical Connections between the Shikoku Pilgrimage and Castles
Overview of Kirihata-ji Temple
Located very close to Kirihata Castle is Kirihata-ji Temple, the 10th temple of the Shikoku 88 Temple Pilgrimage. This temple is situated on the mountainside and is known as an impressive temple on the pilgrimage route, requiring pilgrims to climb 333 stone steps from the Niomon Gate to the main hall.
Kirihata-ji Temple is the only temple among the 88 temples of the Shikoku Pilgrimage that enshrines a reclining Buddha statue as its principal image. Its history is ancient, and legends associated with Kobo Daishi Kukai remain. Furthermore, the large pagoda within the temple grounds is designated as a National Important Cultural Property, making it a site of high historical and architectural value.
Coexistence of Castles and Temples
In medieval Japan, it was not uncommon for castles and temples to exist in close proximity. Temples served not only as religious centers but also as economic and political centers, and feudal lords often acted as protectors of temples.
Regarding the relationship between Kirihata Castle and Kirihata-ji Temple, it is possible that the castle lord protected the temple, and the temple, in turn, played a role in supporting the lord’s authority. It is also thought that temples sometimes functioned as refuges during times of war.
