I am glad that you saw a fox on snow during our cross country skiing tour. And, it is a very good idea to rent a car to drive around this area. However, it is very dangerous driving on snow during winter. I recommend you to take JR train in winter. Our driver will pick you up at the station. If you stay here two nights, you can enjoy cross country skiing tour twice !! Anyways, Thank you very much for staying and please come back again!!
