Château de Jing Shicheng, Mountain fortress in Tottori Prefecture, Japan

Kageishi Castle is a mountain fortress in Tottori Prefecture with stone foundations and walls remaining on a hilltop. The ruins display multiple concentric defensive rings extending outward from the central honmaru area.

The Use clan, local lords, are said to have built the castle around the Nanboku-chō period. According to the Taiheiki, it fell in 1360 to Akamatsu Sadaaki and was retaken by Yamana Tokiuji. In 1580 the Use left under Hashiba Hideyoshi's attack; Isebe Toyonao later entered and received 3,000 koku in Chizu District. It was abandoned around 1617 after the Yamazaki clan moved.

The castle takes its name from Kageishi, the locality in Tottori where it stands. The site is a Tottori City-designated historic site, and the hilltop keep area preserves a yagura-dai, a raised platform for a watchtower, in its northwest corner. Below the main enclosure, the stone-walled rings and the lord's residence traces at the foot of the hill remain visible.

A hiking trail leads up to the ruins with several elevated viewpoints along the way where visitors can see across the Tottori landscape. The path is steep in places and sturdy footwear is recommended for the climb.

The inner layout reveals a thoughtful defensive system with the honmaru as the central core connected by strategic pathways to outer fortification rings. This design allowed defenders to channel attackers through multiple layers of defense.
