We stayed as 3 couples with 2 children in the room. We booked three rooms and we had a great stay at the hotel. The hotel onsen was really good, separated into mens & women - it's swapped over each day so you can experience both. There are also several private onsen that you can book as couples. The breakfast teppanyaki was stunning, several courses and quite a lot of food. The location in the town was really good and you can easily walk around the local area. I recommend driving to the pedestrian suspension bridge over a dam nearby (about 10 mins drive) as it is quite breathtaking to walk across this.
