The 'Maki-ishi-gaki' refers specifically to the use of rounded boulders at the corner of the stone walls to create a curved, durable structure.
The castle grounds include the remnants of Jinpukaku, a Western-style villa built in 1907 to commemorate the visit of Crown Prince Yoshihito.
Tottori Castle served as the strategic seat of power for the Ikeda clan, who ruled the region for over two centuries.
The mountain location made the castle historically difficult to attack due to the steep, natural terrain surrounding the fortress.
The stone walls are constructed using a combination of 'nozura-zumi' (unprocessed stones) and 'uchikomi-hagi' (hammer-shaped stones) techniques.
Tottori Castle Tenkyumaru features a rare architectural style known as the 'Spherical Stone Wall' (Maki-ishi-gaki), designed to provide structural stability and repel intruders. The site marks the former location of the castle's western secondary enclosure, situated on the slopes of Mount Kyusho. Historical records indicate the castle was the stronghold of the Tottori Domain, overseen by the Ikeda clan during the Edo period. Recent preservation efforts have restored significant portions of the stone walls, which overlook the surrounding Tottori plains. Visitors reach the Tenkyumaru area by navigating the hillside trail system within the Jinpukaku ruins complex. The stone wall configuration is distinct for its rounded, massive boulders, differing from typical flat-faced castle masonry. Excavation works here have uncovered artifacts related to daily life within the castle's administrative quarters. The site serves as a vantage point for viewing the Sea of Japan coastline and the Tottori city skyline.
