The castle occupies a section of the Mino mountain range in western Harima Province and is one of the group of castles, covering a wide area, built by the Akamatsu clan, provincial governors during the Muromachi period (1336-1573). The historic site has been developed so it is easier to climb the mountain, and you can visit early stone-walled structures believed to date from the end of the war-torn Sengoku period (roughly corresponding to the 16th century). The masonry, evidently the result of local independently developed civil engineering, produced a low wall describing a circular arc, which follows the topography of the land, but because the corners are not bent in the manner of a ridgeline, it is a precious example of a certain stage in the development of construction techniques.

It was a struggle to secure water in the mountains.
【Trail up to Minami kuruwa (south castle compound)】
Ascend a rocky slope to reach the castle.
Large boulders block the way forward.
At the foot of the mountain path is a steep cliff.
【From the side of Minami kuruwa (south castle compound) / Looking from top to bottom】
The massive structures making use of the natural topography have an overpowering presence.
【Minami kuruwa (south castle compound)】
The masonry of the terraced kuruwa (compound) is visible here and there.
【Minami-kuruwa / drawing arc masonry (left → right)】
The smooth curving masonry has no sangizumi sections.
The exquisite masonry follows the ridge topography.
The vertical face of the kuruwa (compound) is reinforced with stone to create an impressive appearance from outside.

Advancing further toward the center of the mountain castle.
Above the kuruwa (compounds) sandwiched between cliffs,
foundation stones that show the remnants of buildings can be seen here and there.
