My family is planning a ski trip this winter at Nozawa Onsen.
Now that we have to purchase plane tickets, we've discovered that we can fly into either Niigata or Tokyo. Distance-wise, Niigata is closer. What are the transportation options from the Niigata International Airport to Nozawa Onsen in the winter? Riding the train could be an option, but the duration is almost as long as the bus ride from Narita to Nozawa Onsen, so I'm looking for non-train options, if possible.
