Enomoto castle, Japanese castle in Shimotsuke province, Japan.

Enomoto Castle is a fortress ruin situated on elevated terrain in Shimotsuke, built with stone and wooden structures that merge with the natural topography. Several defensive walls and observation points remain visible across the site.

Said to have been founded in 1185 by Oyama Munenaga as a branch castle of Oyama Castle. In 1558 Enomoto Takatsuna became lord, but he was killed in 1564 by Minagawa Toshimune; the castle was contested by the Minagawa, Sano, Hojo and Yuki. In 1590 its lord Kondo Tsunahide died defending Hachioji Castle, and Yuki Harutomo took Enomoto. In 1605 Honda Tadazumi entered with 10,000 koku, founding Enomoto Domain, which reached 28,000 koku before dying out in 1640.

The way the fortress sits on the hillside shows how builders adapted construction to the local landscape. You can see how they used the natural slopes and rocky outcrops as part of their defensive plan.

You reach the ruins by hiking along marked trails that wind through the terrain and provide views of the remains. Information boards at various points help you understand the layout and significance of what you see.

Enomoto Castle was attacked by Minagawa Toshimune in 1564, and its lord Enomoto Takatsuna died in the fighting. In 1590, while its lord Kondo Tsunahide was away defending Hachioji Castle for Hojo Ujiteru and was killed, Yuki Harutomo took the undefended castle.
