Château de Shiodashiro

Château de Shiodashiro is a castle ruin on elevated ground in Nagano Prefecture featuring remains of wooden structures and stone fortifications from the feudal period. The site uses the hill's natural slope as part of its defensive design.

The castle was founded in the 16th century and served as a strategic outpost during regional power struggles in central Japan. It was built to protect and control the territories of local rulers.

The site shows how castles in this region were built to blend with the landscape and use natural obstacles for defense. Visitors can observe today how the defensive layouts made use of the terrain.

The site is accessible by public transport, with a local bus running from Ueda Station to a nearby stop. From there, a path leads uphill through wooded terrain to the ruins above.

The ruin offers sweeping views across the Nagano valley and surrounding mountain ranges. Many visitors overlook this location, though the panorama from above clearly shows why this spot was chosen for defense.
