Nishisakabe Castle is located approximately 4 km northwest of the center of Yokkaichi City, built on a hill approximately 30 meters above sea level.

History of Nishisakabe Castle
Construction History and the “Three-Day Heike Rebellion”
The construction of Nishisakabe Castle is deeply connected to the “Three-Day Heike Rebellion” that occurred in 1204 (Genkyu 1). This rebellion is considered one of the last resistance movements by the remnants of the Heike clan, and was led by Wakana Goro.
According to tradition, Hagiwara Kotaro, acting on Wakana Goro’s orders, built Nishisakabe Castle. The Three-Day Heike Rebellion was suppressed in literally three days, but it is ironic that this short-lived resistance movement became the catalyst for the preservation of a castle in the region.
Castle Lords and Changes During the Muromachi Period
During the Muromachi period, Nishisakabe Castle is said to have become the residence of Akahori Totaro. The Akahori clan later moved to Nakano Castle (Nakano-cho, Yokkaichi City), but it is believed that they used Nishisakabe Castle as their residence before that.
During this period, Nishisakabe Castle functioned as a base for local lords in northern Ise Province. The area around Yokkaichi was a strategic point where the Kuwana, Asake, and Mie districts met, and it is thought that the castle, though small, possessed strategic value.
Developments after the Sengoku Period
With the arrival of the Sengoku period, records of Nishisakabe Castle cease. This region was a sphere of influence for numerous small lords known as the Hokusei Forty-Eight Families, and it is presumed that consolidation into larger castles and the abandonment of castles due to warfare progressed.
With Oda Nobunaga’s invasion of Ise, Toyotomi Hideyoshi’s unification of Japan, and the arrival of the Edo period, Nishisakabe Castle disappeared from the historical stage and was used for farmland and forests.
Remains and Highlights of Nishisakabe Castle
Development Status as Miejoyama Green Park
Currently, the Nishisakabe Castle site has been developed as “Miejoyama Green Park” and is open to local residents. The park features playgrounds and open spaces, serving as a play area for children and a walking trail.
While some remains have been altered due to the park’s development, the basic topography of the castle and its major structures have been preserved, making it a worthwhile historical site for history enthusiasts. It can be considered a good example of a balanced approach between park development and the preservation of remains.
Major Remains That Can Be Confirmed
Earthworks
The most clearly identifiable remains at Nishisakabe Castle are the earthworks. Partially remaining earthworks, approximately 1-2 meters high, surround the area presumed to be the main keep. These are defensive structures built by piling up earth, characteristic of medieval castles, and are valuable remains that convey the castle-building techniques of the time.
The state of preservation of the earthworks varies depending on the location, but in areas that were consciously preserved during park development, the original shape from the time of construction is largely retained. Observing the cross-section of the earthworks, traces of a technique called “hanchiku” (rammed earth construction), where soil was compacted in layers, can be seen in some places.
Kuruwa (Enclosure) Site
The topography reveals traces of multiple enclosures (flat areas) arranged in a stepped pattern around the main enclosure (honmaru). While currently used as a park plaza and pathway, the changes in elevation and terrain allow for inferences about the original layout.
In particular, the highest flat area, presumed to be the main enclosure, measures approximately 40m east-west and 30m north-south, a standard size for a small medieval castle.
Castle Site Monument
A castle site monument inscribed with “Nishisakabe Castle Site” stands at the site of the main enclosure. This monument is an important historical record of the region and serves as a landmark for visitors to recognize that it is a castle site.
The inscription contains basic information such as the construction date and the name of the castle lord, making it a valuable resource for learning about history on-site.
Surrounding Topography and Defensive Structures
Nishisakabe Castle was built on the tip of a hill, with relatively steep slopes on the east and south sides. This technique of utilizing the natural terrain as a substitute for outer moats and cliffs is a typical castle-building technique of the medieval period.
The north and west sides have relatively gentle slopes, but it is presumed that artificial defensive structures such as earthworks and trenches were located on these sides. While the exact layout is unclear due to changes in the terrain, the subtle undulations of the landscape allow us to imagine the defensive lines of the time.
