The family-friendly facility provides free amenities, such as body soap, shampoo and conditioner, as well as safety boxes for valuables, hair dryers and baby chairs and beds. A free footbath for pets is available right outside the bathhouse. The later opening hours indicated for Saturdays also apply to the days before a national holiday. During the 4-day Fuji Rock Festival held at Naeba Ski Resort Yukisasa No Yu is open 24 hours.
