Rex: New hotel connected to the JR Asahikawa station and the AEON mall. Small onsen onsite. Self laundry available. Make sure you book a non-smoking room (if that's what you want) - they are strict.
Rex: Stayed at a nearby hostel which gave me a free onsen pass to this property. It was October, and the place was quiet. I had the indoor+outdoor onsen to myself for 3 hours. Unlimited popsicles as well.
Rex: You can't go wrong staying here if you plan to go to Daisetsuzan. It's walking distance to the cable car station. Meals are prepared by the hosts and change daily. Best part is the free onsen pass
