Gujo Hachiman Castle is classified as a mountain castle, and is located in Gifu Prefecture. During the pre-modern age, it found itself within the borders of Mino Province. It is associated with the Endō, Aoyama clans. Dates in use: 1559 - 1871.

This castle's story began in the mid 1500's with the victory of the Endo clan in battle. Endo Morizaku had the stone walls & foundations built up but then passed away leaving the castle's completion to his descendants. In 1870 the castle was torn down but in 1933, soon after Osaka castle had sprung back to life in concrete, it was decided this castle would be rebuilt using wood.
