柄杓山城, Mountain fortress in Gunma Prefecture, Japan.
Heiryoku-yama Castle is a mountain fortress in Gunma Prefecture with stone walls and foundations positioned on a hilltop overlooking surrounding valleys. Remaining structures reveal the original layout and help visitors understand how the fortification was organized.
The fortress was built in the late 1500s as a military stronghold and played an important role during the armed conflicts of the Sengoku period. It documents a time when fortified mountain positions were strategically crucial for regional power.
The site serves as a gathering place where residents and visitors experience the way of life in this Gunma region through seasonal events and local gatherings. The remnants create a setting where regional traditions remain alive and visible to those who visit.
Walking paths guide visitors through the ruins, with information boards at key points explaining the significance of different areas. Come prepared with sturdy shoes and water, as the site is located on elevated terrain.
The elevated position once allowed defenders to watch movements across multiple valleys simultaneously, giving them control over a wide region. This broad sight line was a significant advantage for defense at that time.
