A mountain castle towering on the border between Totomi and Shinano provinces, telling the story of Takeda Shingen's invasion of Totomi. Restored buildings evoke its past glory.
Takane Castle is a mountain castle located on the 420-meter summit of Kyutoai in Mizukubo-cho, Tenryu-ku, Hamamatsu City, Shizuoka Prefecture. During the Sengoku period (Warring States period), it belonged to the Imagawa clan of Suruga Province. In 1569, it fell to Takeda Shingen's forces during his invasion of Totomi Province. The castle lord, Okuyama Minbushosho Taei, was attacked and the castle was captured by the Togayama clan of Shinano Province, with whom he had familial ties. Subsequently, it was renovated by the Takeda army and served as a key stronghold during their 1572 invasion of Totomi. After the Battle of Nagashino, it was abandoned following the Takeda clan's retreat from Totomi. Takane Castle's strategic location near the border of Totomi and Shinano provinces, overlooking the Akiha Kaido (highway) connecting the two provinces, is a noteworthy feature. The Kawaichi River joins the Mizukubo River near the castle, which was utilized as a natural moat. Takane Castle stands as a precious historical site, preserving the history and grandeur of a Sengoku-era mountain castle. Today, the honmaru (main enclosure) features restored structures such as a turret, main hall, and gate, offering a glimpse into the castle's past. Visitors can also enjoy breathtaking views of Mizukubo town and the majestic mountain range.
