Hiyama Andō Clan Fortified Residence ruins, Medieval castle ruins in Noshiro, Japan.
Hiyama Andō Clan Fortified Residence is a medieval castle ruin in Noshiro built on a mountainside above the Yoneshiro River. The fortified complex spreads across the slope with multiple defensive levels created by earth ridges and dry moats that follow the natural terrain.
The Andō clan built this mountain stronghold during the turbulent Sengoku period to secure their control of the region. Following the establishment of Tokugawa rule, the fortification was abandoned and gradually declined.
The name reflects the Hiyama Andō clan who ruled from this location and shaped the area's identity. Walking through the ruins today, visitors can sense how this stronghold served as a center of power and influence for the surrounding communities.
The ruins are set on a forested mountainside that requires sturdy walking shoes and decent stamina to explore thoroughly. The site is open year-round, but summer visits mean dealing with insects and humidity from the surrounding forest.
Archaeological excavations starting in 2016 revealed this to be one of the largest mountain fortifications in northeastern Japan. These research efforts led to its designation as a National Historic Site and uncovered details about how people defended and lived in this remote stronghold.
