The Ichijōdani Asakura Family Historic Ruins (一乗谷朝倉氏遺跡, Ichijōdani Asakura-shi Iseki?) are historic ruins located in the Kidonouchi section of Fukui, Fukui Prefecture, Japan. This area was controlled by the Asakura clan for 103 years during the Sengoku period.
The castle town was founded in 1471 and became a major cultural, military, and population center in Japan at the time, with a peak population of over 10,000. The town was burnt down in 1573 when the Asakura family was defeated by Oda Nobunaga.
