One of the best-preserved mountain castle ruins in eastern Japan, featuring high stone walls built over 400 years ago.
Karasayama Castle, perched atop Mount Karasayama in Sano City, Tochigi Prefecture, boasts a rich history dating back to the Kamakura period. The Sano clan built the castle during the Kamakura period, and it later fell under the control of various powers, including the Hojo and Tokugawa clans during the Sengoku period. Its high elevation and ingenious defensive systems, utilizing the rugged terrain, earned it a reputation as an impregnable fortress, even challenging the renowned Uesugi Kenshin. Its strategic location was crucial for controlling the surrounding area, making it a vital stronghold for the Sano clan. The appeal of Karasayama Castle extends beyond its historical significance. From the summit, you can enjoy breathtaking panoramic views of Sano City and the distant mountains. The view from Tengu-iwa (Devil's Rock) is particularly spectacular, offering a truly awe-inspiring blend of nature and history. The castle ruins also house Karasayama Jinja Shrine, dedicated to Fujiwara no Hidesato, believed to have been involved in the castle's construction. This creates a unique space where history and faith intersect. Fujiwara no Hidesato was a prominent Heian period warrior known for his role in suppressing the Taira no Masakado Rebellion. A statue of Hidesato is enshrined at the shrine, a testament to his military prowess. Designated as part of Tochigi Prefectural Natural Park, Mount Karasayama features well-maintained hiking trails winding through abundant natural beauty. Strolling along these paths, you may encounter seasonal flowers and birds. Karasayama Castle, a place to fully immerse yourself in history and nature, is a must-visit destination for anyone exploring Tochigi Prefecture.
