History of Mitsutokoyama Castle
Background of Construction and Relationship with the Asakura Clan
While there are no clear historical records regarding the construction period or builder of Mitsutokoyama Castle, its structure and location suggest that it was built as a branch castle of the Asakura clan, who ruled Echizen Province during the Sengoku period.
The Asakura clan was a Sengoku daimyo (feudal lord) that ruled Echizen Province from the late 15th to the late 16th century, with their base in Ichijōdani (present-day Fukui City). The Asakura clan built numerous branch castles within Echizen to strengthen their control over their territory, and it is highly probable that Mitsutokoyama Castle functioned as one of these branch castles.
Role in the Sengoku Period
Mitsutokoyama Castle is presumed to have been responsible for monitoring and defending the western part of Echizen Province, particularly the Oda River basin. This region was close to the Echizen coast, requiring the transport of supplies by sea and preparation against enemy invasions.
During the Sengoku period, Echizen Province was characterized by constant tension between the Asakura clan and the Ikkō-ikki forces of Kaga Province, resulting in the construction of many fortresses along the border. Mitsutokoyama Castle is thought to have played a part in this defensive line.
Developments After the Fall of the Asakura Clan
In 1573 (Tenshō 1), the Asakura clan was destroyed by an attack from Oda Nobunaga. After the fall of the Asakura clan, Echizen Province came under the control of the Oda clan, and later, Shibata Katsuie became the lord of Echizen.
There are no clear records of what role Mitsutokoyama Castle played during this period, or whether it was abandoned. However, like many of the Asakura clan’s branch castles, it is highly likely that its military role ended with the fall of the Asakura clan.
Mitsutokoyama Castle’s Layout and Remains
Castle Structure and Layout
Mitsutokoyama Castle has the typical structure of a medieval mountain castle. The main enclosure (honmaru) is located at the mountaintop, with multiple baileys (kuruwa) arranged in a stepped pattern around it.
The main components are as follows:
- Main Enclosure (Honmaru): The central enclosure located at the highest point of the mountaintop.
- Second and Third Enclosures: Secondary enclosures arranged around the main enclosure.
- Moat: A dry moat dug to block the ridge.
- Vertical Moat: A moat dug along the slope.
- Earthwork: An earthen defensive wall built around the enclosure.
Characteristics of the Main Enclosure (Honmaru)
The main enclosure is located on the mountaintop of Mt. Mitsutoko and was constructed utilizing the relatively flat terrain. Its size is estimated to be approximately 30 meters east-west and 20 meters north-south, a standard size for a medieval mountain castle.
Traces of earthworks can be seen around the main enclosure, indicating that measures were taken to enhance its defensive capabilities. Furthermore, the main enclosure offers a view of the surrounding plains and the Oda River basin, suggesting a layout that emphasized surveillance.
Moats and Vertical Moats
The moats and vertical moats are noteworthy defensive features of Mitsutoyama Castle. Moats are dry moats dug across ridges to prevent enemy incursions along the ridges, and multiple moats have been identified on the north and south sides of the castle.
Vertical moats are moats dug vertically along slopes, preventing attacks from the enemy’s flanks and also serving as rainwater drainage channels. Traces of vertical moats remain on both the east and west sides of the main enclosure at Mitsutoyama Castle.
Arrangement of Enclosures
Several enclosures are arranged in a stepped pattern around the main enclosure. These enclosures are thought to have functioned as defensive positions for the main enclosure, as well as serving as garrisons for soldiers and storage areas for supplies.
The enclosures are separated by steep slopes called “kirigishi,” enhancing their defensive capabilities by making movement between them difficult.
