Stopped by to get a can coffee, stayed for the rest! This was a beautiful, natural rest stop in the mountains. No one was there, but the facility was open to the traveler. There was even a tatami space for the family or a sleepy traveler!
In the back corner there was a counter with brochures and visitor stamps! These stamps are unique to a city, store, area, train, etc. and many Japnese collect them on their travels. They have their own personal books to keep them in or some sell books for the collector.
Do not go into this place with ill intentions though. There are cameras hidden throughout to catch any nefarious activity.
