I booked this hotel without knowing anything about it other than checking the location information and high ratings on a map because it was eligible for a travel discount, but it turned out to be a memorable trip and I'm glad I stayed there. The hot springs date back 250 years, and even Lord Asano bathed there. It's a mineral spring, and now you can bathe in the heated hot springs and the original cold water, so you can take alternate baths. Although it looks like a simple hot spring, it has a slightly thick consistency, and when I asked the neighbors about it afterwards, they told me that it is so effective that skin problems such as heat rash can be cured with just one bath. Perhaps it's because people with sensitive skin often come here, but the inn's cosmetics range is about 4 types, including shampoo, as well as lotion and emulsion. They even have interdental brushes, so I think it's on par with other five-star hotels.It was founded in 1933, and at first there was a cow shed in the back for plowing the rice fields. Now, after several renovations, a pine tree hangs over the entrance, and the openwork glass, which is rare these days, has a maple pattern. Now in its fourth generation, the surrounding inns have gone out of business and it is said to be the last one remaining. Now, due to the coronavirus pandemic, several rooms have been grouped together and the sliding doors removed to make it more spacious. Even though we had our own futons, a kotatsu, and chairs facing each other on the wet veranda, it was still spacious, and we had the luxury of eating in the room next door.For dinner, matsutake rice harvested from the mountain behind the restaurant is served in a large clay pot. Because the area is a place where wild boars roam, the wild boar hotpot, wild boar cutlets, and a Japanese dish made with a rare mushroom called Kuroko are all locally produced for local consumption. He doesn't skimp on his breakfast either, thinking that store-bought cups of natto would be bland, so he adds sticky seaweed to the mix, giving it a vinegary taste. The miso soup is homemade red miso with taro and mushrooms. The salmon was probably what I had bought, but the rice from the local rice terraces was delicious, and even though I had plenty of it in the clay pot, it ran out in no time.There are Japanese-style and Western-style toilets, so if you have a preference, it's a good idea to let them know. Also, the bathroom is accessed via stairs, so it might be difficult for people in wheelchairs, but if you need some rehabilitation, the hot spring facilities in the town just above are less expensive than public baths, and Kurhaus is nearby and has a pool, so it's suitable for elderly people. I wonder if it will be done.This is the perfect inn to relax and enjoy the atmosphere of an Edo spa and the prosperous Showa era.
