I was finally able to stay at a ryokan that is famous as ``Japan's most difficult to book inn.''Not only is the hospitality, food, and facilities on par with the top-ranked ryokan hotels chosen by professionals, but you can also feel the unique concept of this inn.I was only able to stay for one night, but the first thing that stood out to me was the staff. I can sense a strong desire for "hospitality" from everyone. For example, even though the inside of the facility is complex, like a maze, an employee always appears from somewhere and not only smiles and politely tells you where to go, but also offers to accompany you and help you with your family. They even run up the stairs to check if the bathroom is empty, making you feel special. It seems that all employees are treated in this way. Incidentally, the number of employees is said to be 60.The second reason is that the facilities and the various trees within the 10,000 tsubo area sit well together. Trees have been planted so that the inn building cannot be seen from the adjacent road. Each person can spend the day in their own way, strolling through the large Japanese garden, enjoying coffee in the lounge, or reading books in the study.Third, you can enjoy a variety of hot springs, including cave baths, private baths, family baths, and room baths, all of which are fed directly by the source. You can enjoy the feeling of being in a sauna while taking a hot bath inside the cave and then soaking in the warm water at the back. According to people who have actually entered the cave (repeat visitors who come every year), they can stay in the cave for about an hour. And it's a nice touch that there are cut apples, mini tomatoes, etc. placed at the exit. The private bath comes with a Jacuzzi, so you can relieve your fatigue and relax.In addition, the cuisine is based on local production and consumption, using local ingredients as well as vegetables from the restaurant's own garden. This time, the spring wild vegetable dishes and Shinano trout sashimi were very delicious.No wonder so many people stay for consecutive nights.If you stay for consecutive nights, they will prepare a boxed lunch for those who request it for lunch on the second day. Dinner on the first night will be Japanese food, the second night will be Western food (Japanese style), and the third night will be Japanese food.When I checked out, I tried to make a reservation for the next time, but it was already booked."postscript"This is my second time staying for consecutive nights.On the second day, the French restaurant (Sabo "Yagura") was a little smaller in quantity. Also, at noon, I ordered a set of zaru soba and udon from the ``stay lunch menu'' in my room (soft drinks available at the turret).Something I realized again...One is that you can hear the soothing sounds of the river in your room.Second, there are rest areas throughout the facility. The coffee next to the study is delicious, and it's even better if you sit in one of the reclining chairs and enjoy the view.The problem is that there is no Wi-Fi and the TV is small (maybe it's a good thing...).
