Imamura Castle Ruins is a historic site located on Mount Shiroyama (713m altitude) in Ena City, Gifu Prefecture. It is recognized as one of the 'Three Great Mountain Castles of Japan,' alongside Bitchu Matsuyama Castle and Takatoru Castle. The site offers a profound sense of the past through its massive stone walls designed to utilize the steep terrain, the original castle paths, and various historical structures within the castle ruins park.
This location served as a vital stronghold for the Imamura Clan. As a mountain castle built at a high altitude, its defensive structures were masterfully integrated into the natural topography. The surrounding castle town preserves the atmosphere of the Edo period, with traditional buildings and local museums scattered throughout the area, maintaining a unified historical landscape between the castle ruins and the town below.

Within the castle ruins park, you can find significant historical structures such as the Taiko-yagura (drum tower), the Shimoda Utako Study Hall, and the Chishinkan. The well-maintained stone walls and historical stone-paved paths allow visitors to directly observe the architectural ingenuity of a classic Japanese mountain castle. Additionally, the nearby Imamura Historical Museum provides detailed exhibits regarding the history of the Imamura Clan and the castle itself.
Imamura Castle Ruins offers beautiful scenery throughout the seasons. The lush greenery of the mountain castle is particularly striking during the fresh green season of spring and the vibrant autumn foliage period. While the landscape changes with the weather and seasons, the area remains a peaceful and serene environment for historical exploration year-round.

Exploring the castle ruins is akin to a scenic hike through nature. Walking the steep stone-paved paths and undulating terrain allows you to physically experience the defensive capabilities of the ancient fortress. Beyond the ruins, a stroll through the adjacent Imamura Castle Town offers a chance to encounter traditional architecture and local culture in a beautifully preserved setting.
The Imamura Castle Town, spreading out at the foot of the castle, is an area steeped in Edo-period charm. It features traditional residences such as the Katsukawa and Kano houses, as well as museums housed in former Meiji-era townhouses and the historic Imamura Brewing brewery, which boasts over 230 years of history. Exploring these local landmarks provides a multi-dimensional understanding of the region's heritage.
Since reaching the castle ruins requires climbing mountain paths, we highly recommend wearing comfortable, active clothing and sturdy footwear (such as sneakers or trekking shoes). Regarding payments, please note that the availability of cash, credit cards, and transit IC cards varies by facility and shop in the surrounding area. As the castle ruins and the castle town are historical preservation districts, please maintain a quiet and respectful demeanor to preserve the peaceful environment.
