I've been up to the Ginreiso Hut (銀嶺荘) on Mt. Haruka (春香山 - 910m) a number of times now in most seasons. It is one of only three huts in Hokkaido to boast a year-round hut-keeper (Mt. Tarumae Hut and Mt. Muroran's Shiratori Hut being the others). In winter it is a gorgeous, cosy oasis at the foot of Mt. Haruka's upper eastern face, giving prime ski access to easy lapping of tree- and open-runs. While the hut is owned by Tokai University and officially designated as a staff and student retreat facility, the general public are welcome to stay with prior booking when the hutkeeper is present.
