By bus
From Niseko's Hirafu ski fields, Kutchan is an easy 15 minute bus ride. During the day, Donan and Hirafu bus companies operate regular services to Kutchan, one-way fare is about ¥380, depending on where you start and end. The bus will drop off at several points within the boundaries of the town, the terminus being at the JR rail station. Details are in the trail map of the Niseko United. In the winter months, there is also a free Kutchan Night Go Bus service, which runs approximately once an hour from 5pm until 11pm. Strangely enough, to board the free bus, you need to get a free "Kutchan Bus Passport" which is available at all information centres and most hotels.
