Bitchu Matsuyama Castle: The Sky Castle Floating in a Sea of Clouds

In a valley where morning mist gathers, a keep rises alone atop the mountain. Bitchu Matsuyama Castle in Takahashi City, Okayama is a fantastical mountain castle known as the sky castle for the way it seems to float on a sea of clouds. Standing at the highest location among Japan surviving original keeps, its mysterious scenery looks like a fortress hovering in the heavens, letting visitors enjoy both historical romance and spectacular views.

Highlights

Bitchu Matsuyama Castle is a mountain castle built atop Komatsuyama, one peak of Mt. Gagyuzan at about 430 meters elevation. It is one of the 12 surviving original keeps and is known as the highest-altitude among them. The current keep is said to have been built by Mizutani Katsumune in the early Edo period, around the Tenna era (about 1683), and is designated a National Important Cultural Property. Though a compact two-tiered keep, its stone walls that cleverly incorporate natural bedrock and its layout firmly built on the steep summit have the impact of a natural stronghold.

The resident castle cat, Sanjuro, is also popular. Beloved as the cat castle lord, it welcomes many visitors who climb up to the castle.

The Sky Castle in a Sea of Clouds

The reason Bitchu Matsuyama Castle is called the sky castle is the sea of clouds seen on early mornings from autumn to spring. Morning mist rising in the basin wraps around the castle, and the fantastical scene appears in which only the summit keep floats above the clouds. This view is best admired from the observation deck across the way, near Fuigo Pass. It is a rare sight that appears only when weather conditions align, such as a clear, chilly morning with little wind.

Seasonal Enjoyment

The sea of clouds can generally be seen on early mornings from late September to early April, and it is said to be most likely from late October to early December. A clear, calm morning with radiative cooling is the best chance. The castle itself can be visited year-round, and the fresh greenery and autumn foliage seasons also suit a mountain castle. The castle-town streets of Takahashi change their appearance with the seasons.
