Oze and Marunuma Snow Cams & Snow Report
From the Numata exit on the Kan-etsu Expressway, Route 120 heads east and the ski areas follow the valley up the Katashina River. Lodging means the onsen inns, family-run minshuku and pensions scattered along the river in Katashina village. The 12.1 km of Route 120 from the Marunuma ski area entrance to the Konsei Tunnel is shut in winter, and Oku-Nikko Yumoto, over the pass, is approached from the Tochigi side instead.
