Minato Castle

Minato Castle, also known as Minato-jō, was a historic hirayama-style Japanese castle located in Tsuchizaki Minato, within the modern city of Akita in Akita Prefecture, Japan. Although its early origins remain somewhat obscure, historical records suggest it was constructed around 1436, potentially by Ando Yasusue of the Minato branch of the Ando family. Throughout the Muromachi period, the fortress served as the primary residence for the Ando clan, who acted as powerful daimyō ruling over northern Dewa Province. The site later witnessed significant political shifts when Ando Chikasue united two clan branches by moving from Hiyama Castle to Minato, consolidating local power before the turbulent Sengoku era.

The castle's strategic importance declined following the Battle of Sekigahara in the early 17th century. After Akita Sanesue was relocated to Hitachi Province in 1602, Satake Yoshinobu was assigned to the region and immediately began constructing the new Kubota Castle. Consequently, Minato Castle was abandoned in 1604 and eventually fell into ruin. Today, the site is recognized as a historic landmark and is open to the public. It currently functions as part of Tsuchizaki Gaiku Park and includes grounds managed by the City of Akita and the Tsuchizaki Shinmeisha Shrine. Visitors can access the ruins via a short two-minute walk from Tsuchizaki Station, where monuments honoring the Minato-Ando clan stand as reminders of the area's feudal past.
