Minato Castle is a fortress ruin located on elevated terrain near the Ichinoseki River in the Tsuchizaki area. The site features stone foundations and remaining sections of defensive walls from its original construction period.

The castle was built around 1436 by Ando Yasusue and served as the main headquarters of the Ando clan. Control of the region passed to the Satake family in 1602.

The castle grounds show features of medieval Japanese military architecture from the Muromachi period. Visitors can observe the construction methods and engineering approach used in fortress design through the remaining structures.

The site is easily accessible on foot from Tsuchizaki Station, with informational panels located throughout the grounds. These panels explain the historical importance of the structures and help visitors understand the layout.

The castle's elevated location allowed defenders to monitor both land and sea approaches to the region. This position made it a key control point for maritime trade passing through northern Japanese waters.
