Nagurumi Castle, Castle ruins in Minakami, Japan
Nagurumi Castle stands on steep cliffs overlooking the convergence of Tone and Akaya Rivers, forming a natural fortress in the mountains.
Built in 1492 by the Numata clan, the castle gained significance in 1590 when it triggered Toyotomi Hideyoshi's campaign against the Hojo clan.
The castle remains showcase traditional Japanese fortification techniques with multiple bailey structures and earthwork defenses still visible at the site.
The castle site includes an information center open from 9:00 to 16:00, offering guided tours and selling commemorative wooden castle stamps.
The fortress served as a strategic frontline base for Sanada Masayuki during territorial conflicts between major feudal powers of eastern Japan.
