Shikoku Karst Plateau
Japan's Alps - Highland Plateau Paradise
The Shikoku Karst represents one of Japan's three major karst formations, stretching approximately 25 kilometers along the border between Ehime and Kochi prefectures at elevations between 1,100 and 1,400 meters. These distinctive limestone landscapes formed over millions of years from ancient coral reefs that were uplifted through tectonic activity. The plateau's name derives from the Karst region in Slovenia, where similar limestone topography was first scientifically described. For centuries, the highland served as summer grazing land for cattle, a practice that continues today and contributes to the area's pastoral character.
Historically isolated due to steep mountain access and harsh winter conditions, the Shikoku Karst remained sparsely populated, known primarily to local mountain communities. The scenic Skyline Road connecting the plateau's key viewpoints was completed in 1964, transforming accessibility and establishing the area as a driving and motorcycling destination. The distinctive white limestone outcrops dotting the grasslands, combined with the undulating highland topography, earned the plateau its nickname 'Shikoku's Alps' or 'Japan's Switzerland.'
Today, the Shikoku Karst is protected as part of the Tsurugisan Quasi-National Park, balancing conservation with sustainable tourism and traditional cattle grazing. The plateau attracts outdoor enthusiasts, photographers, motorcyclists, and nature lovers seeking Japan's unique highland landscape. Summer brings wildflowers and grazing cattle creating iconic pastoral scenes, while autumn offers golden grass vistas and clear mountain air. The area exemplifies successful coexistence of natural preservation, agricultural tradition, and eco-tourism.
