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.
Excavation of the ruins began in 1967, revealing the shape of the whole town, including the house of the lord, samurai residences, temples, houses of merchants, houses of craft workers, and streets. The samurai residences, merchant houses, etc. have since been restored along the 200 meter long street. Four Japanese gardens were unearthed and partially restored, and the ruins of Ichijodani Castle remain on top of a hill, with a scenic view of Fukui.
