Gujo Hachiman Castle
A hilltop castle overlooking the Yoshida River in Gujo Hachiman, rebuilt in 1933 using traditional wood construction. Its scenic position and the famous 'jumping into the river' summer festival make it one of Gifu's most beloved castles.

Gujo Hachiman Castle stands as a prominent landmark in the Gujo Hachiman region of Gifu Prefecture, overlooking the scenic Yoshida River from its hilltop position. Originally built in 1559, this mountain castle represents an important point in the castle development of central Japan and remains one of the prefectures most recognizable structures.
The castle's history reflects the turbulent period of feudal Japan. Founded during the Sengoku period, it changed hands several times before eventually coming under the control of the Takayama clan. The structure witnessed significant modifications over centuries, adapting to changing military needs and political circumstances until its eventual dismantling during the Meiji period.
What sets this castle apart is its reconstruction in 1933 using traditional wood construction methods that honor original architectural principles. The wooden tower, built without nails in the classic style, showcases authentic craftsmanship and provides visitors with a genuine sense of period design. The castle's elevated position offers panoramic views of the surrounding valleys and river systems, making it both a strategic location and a visually striking landmark.
The castle has earned designation as one of Japan's 100 Famous Castles due to its historical significance and preservation efforts. Beyond its architectural merit, the castle is intimately connected to the region's famous Gujo Odori festival, a summer celebration renowned for its traditional bon dancing. Visitors can reach the castle by hiking the trails that wind up the hillside, with the journey itself offering natural beauty and scenic vistas that complement the historical experience.
Gujo Hachiman Castle is recognized as one of Japan's top 100 castles as designated by the Japan Castle Foundation, a distinction that highlights its historical and architectural importance among the hundreds of castle sites across the country. As a mountain castle, its design reflects the defensive priorities and construction techniques of its era, with origins dating to 1559. Visitors traveling to Gifu Prefecture can explore the site alongside other regional historical attractions.
A fake keep that became a cultural property
Gujo Hachiman is not a reconstruction. It is a mogi tenshu — a “mock keep”, built to look like a castle tower without copying the one that stood here. The official history says so directly: the present tower was built in 1933, modelled on Ogaki Castle, on the stone base of the original.
Then something unusual happened. In 1987 the mock keep was itself designated a Tangible Cultural Property by the city. The copy is now ninety years old, and the imitation has become the thing being preserved.
If you want a single site that shows how slippery “original” gets in Japan, this is it.
And it is made of wood
Almost every castle tower rebuilt in twentieth-century Japan is reinforced concrete. Gujo Hachiman is not. The official site calls the timber construction unusual for a mock keep: four tiers, five floors, in wood, put up in 1933 on the decision of the town mayor of the day, Nakagami Chūhei.
That makes it older, as a wooden building, than most “reconstructed” castle towers in Japan — and it predates the post-war concrete wave entirely.
What was actually here, and what happened to it
The castle was dismantled in 1870, leaving only the stone walls. Those walls are the oldest thing on the hill: they were designated a Gifu Prefecture Historic Site in 1955, thirty-two years before the tower above them got its own designation.
So the site has two layers of heritage, granted three decades apart, for two different reasons: the stone because it is authentic, the tower because the copy has become historic in its own right.
The town below is the other half
Gujo Hachiman’s lords rebuilt the town after a great fire in the Jōō era, running water channels through it so that it would not burn again — the official history calls the result a “water castle town”. The waterways are still the reason people come.
The castle also sits in the story of the Gujo Uprising, a peasant revolt of the Hōreki era that removed the lord of the day. It is one of the better-documented uprisings of the period, and the castle is where its target sat.

Is It Original?
| Original keep still standing? | No — this castle is not among the twelve in Japan whose keep survives from the pre-modern period. Any tower here is a later reconstruction or the site is a ruin. |

The count of twelve surviving keeps is stated independently by the official sites of Matsue, Maruoka, Matsuyama and Bitchu Matsuyama (checked 2026-09-04). Each of the twelve carries its own source on its own page. The classification line below it is this site's own grouping, not an official designation. The designated properties below it come from the Agency for Cultural Affairs national database of designated cultural properties (国指定文化財等データベース), retrieved 2026-08-13. A missing line means no entry was found in that database — not that the property is undesignated.
