Mayumiyama Castle

Mayumiyama Castle is a Japanese mountain fortress in Asuke, Toyota, standing at approximately 300 meters above sea level. Its buildings are linked by steep paths that wind through the hillside terrain of the peak.

The Suzuki clan controlled this fortress until it was captured in 1564 by Tokugawa Ieyasu. This conquest marked a turning point in regional power during the late Warring States period.

The reconstructed fortress features wooden watchtowers and defensive walls that reflect medieval Japanese military design. Visitors can observe how the buildings adapt to the steep terrain without a central keep, creating layered defensive positions.

The fortress sits on a steep mountain and requires effort to climb via mountain paths to reach the upper levels. Visitors should wear appropriate footwear and allow time for the ascent through the terrain.

The fortress belonged to two different local castle groups: the Seven Mansions from the earlier period and the Seven Castles during the later Warring States era. This dual role shows how the site remained important through different historical phases.
