The Hokkaido branch of JR is offering cheap one-day trips for skiing, snowboarding and hot springs in Japan's northern winter wonderland. For about $75 you can get an inclusive trip of train pass, one-day lift pass, and ski/board rental for some of the world's best snow.
Some trips also involve a bus trip to the particular destination, but that's also included in the price.
Your options include:
Niseko Hirafu with view of Mt. Yotei: 6,200 yen
(special note: we just covered Niseko!)
Sahoro with view of Tokachi plain: 10,300 yen
Tomamu with 16 courses: 9,100 yen
Furano with courses for all levels: 5,750 yen
Teine, just 40 minutes from Sapporo: 5,850 yen
