Château de Sanada Honjo

Château de Sanada Honjo is a mountain fortress in Ueda featuring defensive structures spread across multiple hilltops and connected through a network of paths at varying elevations. The ruins display the layered construction typical of medieval Japanese castles with distinct zones positioned to control the surrounding terrain.

The fortress originated during the Kamakura period and was later transformed by the Sanada clan in the 16th century, serving as their principal stronghold until 1583. After that year, the clan shifted their focus to other fortifications and abandoned this location.

The site demonstrates how feudal lords displayed control over valleys and mountain passages through elevated fortifications placed across ridgelines. Visitors can still sense how this location shaped regional life and provided security for settlements below.

Access to the fortress is possible by foot, with visitor parking and restroom facilities located near the summit of the mountain. The various paths allow travelers to explore the site at their own pace and discover different vantage points across the hilltops.

Archaeological digs have uncovered fortification patterns predating the Sanada clan, revealing that this strategic location saw military use across several centuries before becoming well-known. These older traces suggest the site served as a defensive position long before the Sanada family made it their stronghold.
