Château de Tagusarishiro

Tagusarishiro Castle is a Japanese castle in Iwate Prefecture featuring multiple defensive rings with traditional wooden structures built on stone foundations at strategic elevations. The layout creates layers of defense, with each ring designed to complement the others in a coordinated system.

The castle emerged as a military stronghold during Japan's Sengoku period, serving regional lords as a defensive position in the 16th century. It was one of many fortifications built during this era of intense territorial competition.

The castle's layout reveals the social hierarchy of feudal times, with different residential areas positioned according to the rank of samurai families. You can still see how these spaces reflected the strict order of medieval Japanese society.

The site is accessible by local transportation from nearby cities in Iwate Prefecture, with guided tours available upon request. Sturdy footwear is recommended since the terrain is uneven and partly overgrown in places.

The castle was less a single monumental structure and more a network of connected fortifications spread across the landscape. This distributed defense system was designed to resist attacks from multiple directions simultaneously.
