高天神城
Takatenjin Castle is a historic castle in Chūbu dating from the Built in the mid-Muromachi period; fell in 1581, whose lord was Ogasawara clan / Takeda clan / Tokugawa clan.
Overview
Takatenjin Castle, located in Kakegawa, Shizuoka, was a mountain fortress and vital stronghold of Tōtōmi Province, famed by the saying "he who holds Takatenjin holds Tōtōmi." Skillfully employing the terrain of Tsuruo Mountain (elevation 132 meters), the castle was feared by Sengoku warlords as an impregnable fortress protected by natural sheer cliffs and deep ravines.
In Tenshō 2 (1574), Takeda Katsuyori, successor to Takeda Shingen, led a large army to assault and capture Takatenjin Castle as a strategic foothold for advancing into Tōtōmi. In response, Tokugawa Ieyasu sought to retake the castle. From Tenshō 8 (1580) onward, the castle fell under siege. With provisions exhausted within the castle and no relief forces arriving, castle commander Okabe Motonobu launched a tragic final charge in Tenshō 9 (1581) and perished in battle.
The fall of Takatenjin Castle became a pivotal historical event contributing to the Takeda clan's destruction. Ieyasu's withholding of relief forces severely damaged the morale of Takeda garrisons at other strongholds, hastening the clan's total collapse the following year. The "grudge of Takatenjin Castle" was transmitted through the Edo period, inscribed in history as an episode exemplifying the military ruthlessness of Tokugawa rule.
The castle ruins preserve numerous stone walls, earthen ramparts, and fortified enclosures in excellent condition, with many artifacts recovered through archaeological excavation. The ruins sprawl across the steep mountaintop and are accessible as a popular hiking course via mountain trails.
Connection to Swords
The relationship between Takatenjin Castle and swords is concentrated in the symbolic significance of the Takeda clan's formidable military culture and the place embodying its downfall. The elite units of the Takeda army wore practical swords as their primary weapons, and in the battle for Takatenjin Castle, many warlords fought wielding renowned blades. In the desperate final sortie of Tenshō 9, Commander Okabe Motonobu and the castle garrison refused surrender and made their final charge. Some of the swords used in this action are said to have been confiscated by the Tokugawa forces after the battle, and there are examples of heirloom swords transmitted as "blades from the fall of Takatenjin Castle" preserved in temples, shrines, and museums throughout Shizuoka Prefecture. Regarding the swords carried by Takeda Katsuyori during the conquest of Takatenjin Castle, there exist swords enshrined at shrines connected to the Takeda clan in Kai as "swords possessed by Katsuyori." After the fall of the Takeda clan, these swords were distributed between the Tokugawa and Oda houses, and continue to be transmitted in museums and shrines throughout the country as blades connected to the Takeda clan. Although Tōtōmi (western Shizuoka Prefecture) has not historically been a center of sword forging, the renowned blades brought by warlords involved in the battle for Takatenjin Castle have been transmitted to the region, and the Kakegawa Municipal Local History Museum displays works related to arms and swords. Takatenjin Castle is positioned in sword history as a place symbolizing the "turning point of famous blades" at the end of the Sengoku period.
