Mount Yunomaru, Lava dome summit in Ueda, Japan
Mount Yunomaru rises to 2,101 meters and spans across the borders of Nagano and Gunma Prefectures. Its steep slopes are covered with Japanese azalea plants that characterize the landscape.
The mountain formed through volcanic activity from the Eboshi Volcano Group in ancient times. This geological formation shaped the structure of the entire region today.
The mountain appears in two lists of famous peaks, one celebrating the Kanto region and another for Gunma. Visitors travel from across Japan to experience these recognized heights and their views.
Several hiking trails of varying difficulty lead to the summit with parking areas and information boards at the main access points. Check weather conditions before your visit and prepare for steep sections on the route.
The slopes maintain a rare community of Japanese azalea plants that resemble a natural botanical garden when in bloom. This plant diversity makes the area special for nature and botany enthusiasts.
