The hotel itself is very close to the JR station, but unfortunately, JR trains to Tomakomai are very infrequent, running only about once an hour in the evening. You really have to plan your time carefully, otherwise, like me, I waited a full 48 minutes at Minami-Chitose before a train returned to Tomakomai. The hotel staff were very helpful; although they only spoke Japanese, they understood what I needed and were happy to assist me.
