Tsunomure Castle is a mountain fortress perched at an altitude of 576 meters While many other castles fell during large-scale conflicts, Tsunomure Castle remained impenetrable, earning its place as a symbol of Kusu.
Today, the castle’s stone walls, including those of the Ninomaru and Sannomaru, remain as testaments to its historical significance. Built using the anou-zumi technique – where unshaped stones are expertly stacked – the site offers a glimpse into the evolution from earthen to stone-based castles. In 2005, it was designated as a National Historic Site.
Why not take a walk through the historical legacy left by Kakumure Castle?
One of the highlights is the 7-meter-high stone wall near the Ninomaru’s main gate, showcasing the remarkable craftsmanship of historical stone masons.
As you make your way up to the castle, there are numerous historical artifacts, such as the Tsunomure Shrine and scattered stone statues, each telling its own story.
The observation point along the way offers stunning viewpoints, including vistas of Mt. Hane, Mt. Kirikabu, and the Kuju mountain range. Reaching the main keep at the summit provides a profound sense of accomplishment and connection to the past.
For those arriving by car, parking is available near the Sannomaru, providing convenient access to the castle trail.
