What Is Gujo Hachiman Castle? One of Japan’s Oldest Wooden-Rebuilt Castles
Gujo Hachiman Castle (Gujō Hachiman-jō) in Gujo City, Gifu Prefecture, stands atop Mt. Hachiman (Hachimanyama).
The keep was rebuilt in wood in 1933, and is known as one of Japan’s oldest wooden reconstructed castle keeps.
The view from the castle has an atmosphere that evokes a “castle in the sky,” and depending on the season and weather conditions, you may even see misty scenery resembling a sea of clouds.
Beyond its architectural beauty, the castle’s appeal also lies in its historical background dating back to the Sengoku period and the pleasure of exploring the water-lined castle town below.
In particular, the surrounding landscape turns vivid during the autumn foliage season, and events such as maple-leaf light-ups may be held.

The History of Gujo Hachiman Castle
Gujo Hachiman Castle originated as a fortress built on Mt. Hachiman during the Sengoku period, and through changes of lords over time, a castle town was formed.
After the Meiji Restoration, the buildings were dismantled due to the abolition of castles, but in 1933 a wooden mock keep and related structures were rebuilt, and today it stands as a symbol watching over the town.
