Mukaihaguroyama Castle

Mukaihaguroyama Castle is a mountain fortress in Aizumisato built across two peaks of Mount Iwasaki with defensive structures, stone walls, and earthen embankments forming its main elements. The castle complex occupies several strategic zones on the heights and displays traditional Japanese architectural design.

The castle was built in 1668 during the Edo period and later served as a residence for Ashina Moriuji after his retirement. It also played an important role in protecting the southern territories of the region.

The castle grounds feature traces of a traditional Japanese garden near the masugata-gate, where you can still see the refined tastes of the feudal lords who lived here. These design choices tell you much about how the local elite shaped their surroundings during their time.

You reach the castle via marked trails that lead up to the mountain summit and are clearly marked throughout. Before your visit, prepare for mountain terrain and wear proper hiking shoes.

The fortress ranks among Japan's five largest mountain castles and stands alongside Kasugayama, Nanao, Odani, and Gassantoda on a special list. This classification makes it a rare and valuable site for castle enthusiasts.
