We're 300 meters from the bus stop shown here. There's a shuttle bus going in a loop around the mountain every 15 minutes, going both east and west.
Annupuri is 5 minutes, Niseko village 2 minutes and Hirafu is 8-9 minutes.
It's a 650 metre walk to the closest lift and you can ski back to the cabin.
There's a great spread of restaurants between those places as well. A car would be ideal, but plenty of bus services to access lifts, Onsens, and the villages like Hirafu. Buses are free with your day lift ticket.
