Taki-no Castle, Japanese castle ruins and park in Tokorozawa, Japan

Taki-no Castle is a hilltop fortress site overlooking the Yanase River with multiple defensive sections separated by earthen walls and dry moats. The layout follows the mountain castle style where each level served distinct defensive purposes.

The castle's documented form dates from the 15th century under Ōishi Sadahisa, a retainer of the Uesugi and deputy of Musashi Province. It passed to the Later Hōjō and served Hōjō Ujiteru as a branch castle of Takiyama, where troops gathered before the 1564 campaign into Shimotsuke. In 1590 Asano Nagamasa's Toyotomi force attacked from the north and took it; it was abandoned as Tokugawa Ieyasu entered the Kantō.

The castle's name comes from Kintsuno Falls, a small waterfall that once ran through a ravine east of the outer bailey; only a trickle on the rocky slope remains, feeding the pond in the park below. The main bailey now holds Shiroyama Shrine, and the surrounding park is known for plum and cherry blossoms in spring.

Walking paths connect the different sections and lead past the preserved walls and dry moats, making the site easy to navigate on foot. Wearing comfortable shoes is advisable since the terrain includes inclines and some paths may be uneven in places.

The 1976 reinforcement of the collapsed main bailey cliff exposed nine horizontal cave tombs from around the 7th century, yielding gold rings, glass beads and Sue ware. The tombs were backfilled after excavation, and their burial chambers were laid out so regularly that more are thought to continue east-west.
