You can make your way to this spa, using the free shuttle service (2:30 - 3:00 hour drive) from the Sapporo Bus Terminal, that is right next to the Sapporo JR Station. The shuttle must be booked in advance.
The room we had, is a typical Japanese onsen Western style, with two beds, TV, fridge, etc. The traditional Japanese style room using futons is available at a higher price. As for the buffet dinner, it should appease the most discriminating palate. With sushi, dumplings, pasta, noodles, steak, sea food, and the list goes on, good luck with sampling all. If you get to the dining room prior to opening, you should be able to reserve a table of your choice
And the buffet breakfast will too be considered to be quite appetizing to a Western palate. One thing to remember is that alcoholic and soft drinks will incur an additional cost, though there is a free drink bar available with coffee, tea, water, and a small assortment of juices.
As for their facilities, they have two extremely large segregated public hot spring spas, indoor co-ed heated hot spring pool and a very large co-ed outdoor hot spring pool. And if you are tired of being wet, you can always go for a walk along the river, play ping pong, there is also a games room, or visit the other spas in the area.
The one major issue I have, is that the public hot spring spas are crowded during the day and evening. Best time to hit them is late in the evening, well after dinner or after midnight - then you can have the spa almost all to yourself.
Issue #2 is the Departure time from the Sapporo Bus Terminal to the Hotel, and the Departure time from the Hotel to Sapporo Bus Terminal - there is very little time left with a one night stay to do a little hiking and visit the nearby hotels that are part of the chain that Yumoto Dai Ni Meisuitei belongs to, and take advantage of the shared privileges.
Be forewarned, that English is not widely spoken in these here parts. This hotel is in an isolated area, therefore, very little shopping. And no Tipping - fantastic.
To really have a leisurely time here, you need to spend at least two nights, if it is within your budget.
Would I recommend this establishment: Definitely
Would we return: Yes, though we would go for two nights, instead of one.
