Sakado Castle

Sakado Castle is a medieval fortress in Minamiuonuma built at an elevation of 634 meters (2,080 feet) across multiple ridges overlooking the Uono River. The ruins feature stone walls, defensive structures, and dry moats that follow the mountain terrain.

The fortress was built in 1510 by the Nagao clan during the era of territorial wars between the Uesugi and Hojo clans. Its position allowed control over silver resources and trade routes that connected the region to neighboring provinces.

The castle exemplifies medieval Japanese military architecture through its innovative design that incorporated natural terrain features for defensive purposes.

Multiple hiking trails connect Muikamachi Station to the ruins, making the ascent accessible to visitors with varying fitness levels. Guided tours are available, and visitors should plan for a full outing and wear sturdy footwear for the mountain paths.

The castle protected valuable silver mines of Ueda and controlled important trade routes connecting Echigo Province with the Kanto region.
