The Tanba Kameyama Castle Ruins (also known as Kameyama Castle) is a significant historical site located in Kameoka City, Kyoto Prefecture. This site is far more than a simple Sengoku-period castle ruin; it possesses a highly unique historical background as it was later developed as the center for the "Oomoto" new religion in the modern era. The layers of Japanese history are deeply intertwined here, from the castle's construction by Akechi Mitsuhide to its development into a modern-style castle during the Edo period, and finally its transformation into a sacred ground with the construction of shrines by Oomoto. The coexistence of ancient castle remains and religious architecture creates a landscape unlike any other castle site in Japan.
The history of this land traces back to the legendary Sengoku-era hero, Akechi Mitsuhide. It is said that the fortification began around 1578 when Mitsuhide established it as a base for ruling the Tanba region. Following the era of Toyotomi Hideyoshi, the site underwent major reconstruction into a modern-style castle under the direction of Todo Takatora during the Tokugawa Shogunate. It is said that a five-story castle tower once stood tall over the landscape.
After the Meiji Restoration, the land was purchased by the leader of the Oomoto religion, Onisaburo Exit, and transformed into a sacred land known as "Tenon-kyo." However, the site experienced turbulent times, including heavy government suppression during the Second Oomoto Incident, which led to the destruction of many shrines and facilities. In the post-war era, ownership returned to Oomoto, and today, the site serves as a religious sanctuary while preserving its historical remains.
The greatest attraction of the Tanba Kameyama Castle Ruins is the seamless integration of Sengoku/Edo-period castle remains with modern religious architecture. You can see the traces of where the castle tower once stood, alongside stone walls and earthen ramparts that have blended into the current landscape. The shrines built by Oomoto and the surrounding spaces that evoke the past serve as important elements in understanding the evolution of Japanese spiritual culture. For history enthusiasts, observing how the castle structure utilizes the natural topography is a fascinating experience.
You can enjoy exploring the history regardless of the season. On clear days, the daytime atmosphere is particularly wonderful, allowing you to fully appreciate the solemnity of the castle ruins, the surrounding nature, and the religious facilities. In the late afternoon, the air becomes quiet and serene as the sun sets behind the surrounding mountains, offering a profound sense of historical weight. Please note that because this is a religious site, visitors are expected to maintain a quiet and respectful demeanor.
Visitors can enjoy a walk through the history of this site. You can feel the atmosphere of a place that transitioned from a samurai stronghold to a religious sanctuary.

Kameoka City is home to many other historical spots. You can explore areas related to Akechi Mitsuhide or enjoy the rich nature of the Kameoka Basin. You might even find fragments of history in nearby facilities, such as the Chiyokawa Elementary School, where parts of the castle gates were relocated. We recommend planning a route that combines a visit here with other historical explorations in the area.
As the site includes slopes, unpaved paths, and uneven terrain, we highly recommend wearing comfortable walking shoes. Because the site has the character of a religious facility, it is important to maintain a quiet and respectful attitude. Regarding payments, please check in advance if any fees are required at the local reception. While there are some English signs, please observe basic etiquette and respect the sanctity of the site.
