Karst topography is terrain created on the earth’s surface by dissolution of soluble rocks. The Karst highlands including Medurudaira and Onogahara extending approximately 25km, from 1,000m to 1,485m above sea level, are scenic driving routes. While the roads are closed during the snowy winter period, they are the perfect place to enjoy driving, cycling and camping through spring, summer and autumn. Relax and enjoy the refreshing scenery of cows feeding on a meadow or the starry sky at night.
