The Kono Clan Castle Site Monument (Kono-shi Joshi-hi) is a stone monument in Dogo Park. Its inscription records the history of the Kono clan, who made Yuzuki Castle here their base in the medieval period. It was erected in November 1941 (Showa 16) by Kukaku-ni. It is included in Dogo Park's "Haiku Monument Tour Course", and the park also has a separate monument recording the "Origin of the Yuzuki Castle Site".
Yuzuki Castle and the Kono clan
Yuzuki Castle was built around 1335 (Kenmu 2) by the Kono clan, who were the military governors (shugo) of Iyo Province. For about 250 years afterward it served as the Kono base. In 1585 (Tensho 13), however, it was attacked by forces under Kobayakawa Takakage and others in Toyotomi Hideyoshi's invasion of Shikoku, and after about a month under siege the Kono clan surrendered. The castle was abandoned around 1587 (Tensho 15).
The castle site was developed as the prefectural Dogo Park in 1888 (Meiji 21), and after archaeological excavation, samurai residences, earthen walls and other structures were reconstructed. It was designated a National Historic Site in 2002 (Heisei 14) and was also selected as one of Japan's 100 Famous Castles.
