Takiyama Castle

Takiyama Castle (滝山城, Takiyama-jō) was a Japanese castle located in what is now the Tani neighborhood of the city of Hachiōji, Tokyo, Japan. Its ruins have protected as a National Historic Site since 2007.

Takiyama Castle is located on a long ridge south of the Tama River, next to the confluence of the Tama River coming from the Ome area with the Aki River from the Okutama areas of Musashi Province. The castle site and surrounding area are within the borders of the Takiyama Prefectural Natural Park.

During the Muromachi period, this portion of Musashi Province was ruled by the Ōishi clan, vassals of the Ogigayatsu-branch of the Uesugi clan and shugodai of Musashi Province. They were one of the major military powers in the Kantō region. Ōishi Sadashige constructed Takiyama Castle in 1521 to replace an earlier stronghold at Takatsuki, approximately one kilometer away. However, the Uesugi clan was soon eclipsed by the rising power of the Late Hōjō clan based at Odawara, who had conquered all of neighboring Sagami Province by around 1530. The Hōjō then set their sights north, decisively defeating the Uesugi at the 1546 Siege of Kawagoe Castle. The Ōishi clan was forced to submit to Hōjō Ujiteru, who made Takiyama Castle his field headquarters for the conquest of Musashi.

Ujiteru expanded and improved the defences of the castle. Prior to Hōjō Ujiteru, Takiyama Castle was a simple structure with two enclosures, the Honmaru (central bailey) or Nakanomaru (intermediate bailey) with rudimentary defenses. Ujiteru added a Ninomaru (second bailey), Sannomaru (third bailey) and Komiya Kuruwa (Komiya enclosure), each surrounded by dry moats and earthen ramparts. Each gate was fortified with a yagura tower and with an umadashi buffer area in front of the gate to make a direct front assault impossible.

In 1569, Takeda Shingen, the warlord of Kai Province attempted to seize the castle during the Siege of Todoriko. The Takeda army had 20,000 men led by Takeda Katsuyori and seized the opposite bank of the Tama River. However, the true purpose of the attack was feint in an attempt to draw off Hōjō forces from Shingen's real target, which was Odawara Castle. Although Shingen managed to encircle and threaten Odawara for a week, he eventually gave up and returned to Kai Province, and the forces at Takiyama Castle were also withdrawn.
