鮎貝城

Ayukainjo is a mountain castle in Akita Prefecture built on steep slopes with multiple layers of defensive structures. The ruins feature stone walls and watchtowers positioned at key points along the hillside terrain.

The fortress was founded in 1387 and underwent several renovations over the following centuries as military needs evolved. These changes reflected how regional powers adapted their defenses to new conditions and threats.

The castle grounds reflect how feudal lords adapted their defenses to the local landscape and mountain environment. Walking through the ruins, visitors can see how the steep terrain shaped both the military strategy and daily life of those who lived here.

The castle is roughly 15 minutes on foot from the nearest railway station, and parking is available nearby. Visiting during warmer months is easier because the steep slopes make the walk demanding.

The castle merges so skillfully with the natural slopes that it is hard to tell where the landscape ends and human construction begins. This seamless blend of structure and terrain was typical of Japanese castle design from this period.
