Trains from Sapporo to Niseko
Although it can be a little complex, it’s possible to take a train from the New Chitose Airport or Sapporo City to Niseko. From New Chitose airport a fast train takes about 35 minutes to Sapporo. A train from Sapporo to Otaru takes from 32 to 50 minutes, and from there you can take a train to Kutchan takes between 1 hour and 1:20 hours. Niseko station is a further 15-20 minutes on from Kutchan. For train timetables and fares take a look at Hyperdia.
Kutchan station is located in a better position if you are travelling to Hirafu or Hanazono, whilst Niseko station is a touch easier for those staying in Niseko Village (Higashiyama) or Annupuri. Buses are available from Kutchan train station, and taxis available from both train stations, while some lodgings provide a pick-up service. A taxi between Kutchan station and Hirafu costs about ¥3500 and takes about 15 minutes.
Trains from Honshu to Niseko
A tunnel runs between Honshu, which is the main island of Japan, and Hokkaido. Trains between Shin-Aomori (at the northern tip of Honshu) and Kutchan take as little as 4.5 hours as the first part of the trip is a bullet train. It’s about 3 hours from Tokyo to Shin-Aomori by bullet train. However, from Tokyo it is more expensive to take the train than to simply fly to Sapporo and take either a train or the bus to Niseko. Once again see Hyperdia for train timetables and fares.
