Yunomaru is a ski area located in Tomi City in the eastern region of Nagano Prefecture.
In fact, it is only just in Nagano, as it is on the border with Tsumagoi Village in Gunma Prefecture.
The ski lifts and ski runs of Yunomara are on either side of a road, with the larger section on the eastern side. There is one triple lift (405m) and four pair lifts (466m, 603m, 760m and 1,040m) in that area. The western side has just one 520m pair lift. The two areas are close but not connected, so you need to take off skis or snowboard to get from one to the other.
The base of Yunomaru is at a high elevation of is at 1710m and the area often enjoys good snow conditions. In fact, its catchphrase is 'the closest powder snow ski resort to Tokyo'.
Yunomaru dates back to 1928, with the main development of the ski area in the early 1960s.

Introduction to the region
Nagano Prefecture is located in the Chubu region of the main island of Honshu. It is one of only eight landlocked prefectures in Japan, bordered by Niigata, Gunma, Saitama, Yamanashi, Shizuoka, Aichi, Gifu, and Toyama.
Nagano Prefecture is sometimes referred to as 'the roof of Japan' because of the steep, rugged terrain of the many 2,000-3,000m mountains that comprise the Japan Alps. The Northern Alps are located along the northwestern region bordering Gifu and Toyama. The Central Alps are in the southwestern region, and the Southern Alps are along the southeastern border.
After Hokkaido, Nagano Prefecture is home to the second-largest number of ski areas in Japan. It has multiple world-class winter sports resorts within its boundaries, and some were venues for the main events of the 1998 Nagano Winter Olympics. There are ski areas throughout the mountains of Nagano Prefecture, but the majority are in the northern and central regions.
Yunomaru is the only ski area currently operating in Tomi City.
