Iwakisan Kōgoishi

The stone walls of Iwakisan Kōgoishi rise on Mount Iwaki, featuring multiple defensive gates and ancient water management structures within its perimeter.

Built after Japan's defeat at the Battle of Hakusukinoe in 663 AD, this fortress incorporated construction techniques brought by Baekje people from the Korean Peninsula.

The fortress demonstrates the evolution of Japanese military architecture, shifting from wooden structures to stone fortifications during the medieval period.

Visitors can access the site through local mountain paths, with a 90-minute walking route connecting the West Water Gate, North Water Gate, and North Gate.

The stone fortification contains Kutsuisu, a large foundation stone at the North Gate that displays exceptional masonry techniques from the Asuka period.
