Naegi Castle Ruins

The Naegi Castle Ruins, located in Nakatsugawa City, Gifu Prefecture, are the remains of a mountain castle built on a steep rocky hill overlooking the Kiso River. Characterized by a unique structure that ingeniously used massive natural bedrock to build up stone walls and structures, it is also called the "castle in the sky" and the "castle of giant rocks." In recent years it has grown popular as a scenic spot, a famous place where you can feel the energy of nature and history.

Highlights

- Keep Platform: From the platform built on the former keep site, a 360-degree panorama spreads out, with the Kiso River below and Mount Ena straight ahead. - Stone Walls Using Giant Rocks: The landscape where natural giant boulders and hand-built stone walls become one has a power seen nowhere else, captivating castle and history lovers. - Sea of Clouds: When conditions align, you may encounter the dreamlike "castle in the sky" scene with the ruins floating above a sea of clouds.

Enjoying the Seasons

Adorned with fresh greenery in spring and colorful foliage in autumn, the ruins offer stunning views in every season. A sea of clouds tends to appear on windless mornings from late autumn to winter, when radiative cooling brings a chill. The view at dusk is also beautiful, and the time when the sky turns orange is exceptional.
