Some good steep tree skiing here with no crowds at all (even on weekends). No night life or bars so you make your own fun in an izakaya (casual dining spot). Not as much snow as it's more famous neighbours but seems to maintain snow quality for longer after dumps due to the colder, drier weather. Really quick to get here by train (or drive) from the airport so a good place to start a Hokkaido tour, two days would be a good amount of time here in my opinion, we skied here for four but it was one too many.
