Château d'Iwaya, Mountain fortress in Mimasaka Province, Japan
The castle stands at an elevation of 483 meters on a mountain peak in present-day Tsuyama City, Okayama Prefecture, with stone walls surrounding three sides.
Yamana Norikyio constructed the castle in 1441 as a military stronghold, which later became a target of conflicts between different feudal lords of the region.
The castle layout incorporates natural geographical features, including cliffs and slopes, following traditional Japanese fortification principles of the medieval period.
The castle site contains preserved foundation stones, defensive trenches, and baileys, which visitors can explore through marked pathways.
The fortress possessed two water sources, a well and the Ryujin pond, enabling sustained resistance during extended sieges.
