Takeda Castle, Japanese castle ruins on Mount Shiroyama in Asago, Japan
Takeda Castle is a set of stone foundations arranged across a wooded hilltop in Hyōgo Prefecture, with terraced walls marking where buildings once stood. The layout follows the natural contours of the mountain, creating a series of connected platforms that reveal the original defensive structure.
The fortress was founded during the 15th century to guard silver mines and served as a border stronghold between rival clans. Authorities ordered its dismantling after the feudal period ended, leaving only the stone walls behind.
Local residents call it the Castle in the Sky because mist often wraps the mountain below the ruins. This nickname reflects how the site has become part of the area's identity, drawing photographers and hikers who time their visits to witness the cloud formations.
Two footpaths lead up from the railway station to the ruins, with the climb taking around 40 minutes. A shuttle bus operates during peak visiting seasons in autumn and spring, making the ascent easier for those who prefer not to hike.
On clear autumn mornings a layer of clouds forms below the summit, making the ruins appear suspended above a white sea. This weather phenomenon occurs only under specific conditions and transforms the site into a scene from a folktale.
