Do not know answer but I was there three days and never saw hotel staff at the Onsen or related facilities

Hello, I’m pretty sure there are but as we were there in deep snow there were no opportunities for us so we didn’t really ask. Sorry I can’t be of more help!

No sign, but we were contacted by the hotel a couple of days before our arrival, and between some questions from them they've attached a map of where you need to meet the van. It's just outside the station and he can has the name of the hotel, so pretty easy to find. If they don't get in contact, I would email them to ask for the map. Enjoy

Yes, there is a very good possibility that there will be snow. I cannot give you a specific room number, however you want to book a Seiryuan Type room. When you make your reservation, which should be now as the ryokan is very popular, specify that you want an outside, open-air bath so that you can hear the passing river. You can only hear the river from outside as most of the rooms windows do not open, which is unfortunate. You can hear the river, but not see it. All rooms basically have the same, hill-facing, view. Pray for snow, it's beautiful. BTW, there is also a private lounge open from 15:00 - 19:00. It is only available to frequent guests and it's quite pleasant. Complimentary wine and champagne is served. It is my understanding that other guests can gain access at a special rate. You should inquire when you make your reservation.
