Amagiri Castle

Amagiri Castle is a mountain fortress in Zentsuji that rises about 350 meters above sea level and once controlled access to nearby port areas. Its ruins stretch across ridgelines with multiple levels of walls and enclosures built to work with the natural terrain.

The fortress was built in 1364 by Kagawa Kagenori as a secondary stronghold to strengthen the defenses of the Tadotsu area. It served as an important part of regional military strategy during the Muromachi period.

The fortress shares its mountainside with Iyadani-ji temple, which serves as station 71 on the Shikoku Pilgrimage route and holds special meaning for pilgrims. Visitors can experience both sites together, noticing how the sacred space and the old fortress coexist on the same slopes.

The ruins are best reached on foot, with a walk of about 20 to 30 minutes from Zentsuji Station required to reach the site. The terrain is relatively open with little shade, so bring water and sun protection for a comfortable visit.

The fortress complex stretches across long distances along mountain ridges, using natural rock formations as part of its defensive walls. This approach shows how builders of that era made the landscape itself serve their military needs.
