Château d'Ishiwakijo, Mountain fortress in Shizuoka Prefecture, Japan
The Ishiwakijo Castle sits atop steep terrain, utilizing natural mountain defenses with stone walls and wooden structures for military protection.
During the Sengoku period of the 15th century, this fortress served as a strategic position for monitoring movements along the ancient Tokaido road.
The castle design follows traditional Japanese mountain fortification principles, incorporating local stone materials and architectural techniques of medieval Japan.
The remains of stone foundations and defensive walls indicate the exact layout of former military installations at different elevation points.
The castle location offers views extending to Mount Fuji, making it a notable observation point for tracking regional activities in feudal times.
