As far as business hotels next to train stations go, Hotel Folkloro Ominato is a good choice. Free breakfast (not a huge selection but I was satisfied), free wifi, free parking, staff are polite and speak some English. Rooms are very clean and fairly quiet. My only complaint would be the price. For two people, one night on a Saturday, the price was 16000 yen. That seems a bit high to me based on my previous experience. For me, this was a four-star experience within the limited realm of Japanese business hotels.
We stayed here after a day of exploring yagen valley and mt.osore (both withon driving distance). The room is not much to speak of, your typical budget hotel room near a train station. It was neat and tidy. No safe. Breakfast was buffet style and was fine. Plenty of free parking around back. Staff was very polite and spoke a little English. There are also plenty of convenience stores, grocery stores, etc nearby. The price was a tad high for what you get, but there's not much other options in the area.
