Mana Residence, located about 17km from JR Nasu-Shiobara Station, is a quiet inn nestled in the majestic Nasu Mountain Range.The first floor, centering on the entrance lobby, has been completely renovated with a Taisho Roman motif. It has a modern and calm atmosphere while maintaining a Japanese taste. Additional facilities are also available, including a gallery with stained glass, paintings, and other works. In addition, at the restaurant ``Hanatoro,'' you can enjoy dishes that make use of seasonal highland vegetables.What is unique is Arashi no Yu, which is covered with 15 types of medicinal stones. Mineral-rich spring water is poured over medicinal ore on the floor to create a room with a room temperature of 45 degrees and humidity of around 80%. The steam generated indoors is turned into nano-mist of ultra-fine particles, allowing the human body to ingest important minerals and sweat profusely. In addition, waste products can be excreted from the body not only through the sweat glands but also through the sebaceous glands. There is also an open-air bath and an indoor bath.When I visited around 3pm on a holiday, there were no customers in the lobby. It is a small inn with 10 rooms in total.*Japanese-style standard room 1 night with 2 meals 16,600 yenThe rooms are nostalgic inn style. It is a shame that there is no wide edge of the mystery space. Arashi no Yu is in a separate building, so change into sandals and head there. It may give you an image of a ceramic (rock) board bath made of gravel, but the sweat produced is amazing. This beer looks good. Dinner will be served at the restaurant from 6pm.*Ebisu Meister 700 yen*Martini (half bottle) 1,500 yen・Appetizer appetizerUrui soak, mizuna and soft white onion with white dressing, firefly squid and udon with vinegar miso・StealingBamboo shoots, shiitake mushrooms, ganmo, butterbur, warabi, fumu・SashimiPalm trout, sea bream, sweet shrimp・Steamed foodChawanmushi・Fried foodCod sprouts, Udo, Kogomi, Snap peas・Meat dishesPoiled Nasunogahara beef fillet・MealsClams pot rice, red soup stock, pickles・Water sweetsSeasonal roll cake/fruitSince it is a small inn, I was impressed by the fact that there was no need to line up the food in advance, and the food was brought out each time. It's good that the wild vegetables are delicious. The clam kamameshi with ginger at the end was also good.Breakfast starts at 8:30 at the restaurant.・Kombu tsukudani, grated whitebait, mustard cod roe, natto, grilled seaweed, boiled komatsuna and fried tofu, daily small bowl, seasonal vegetable salad, salt-grilled mackerel, omelet, rice, miso soup, pickled vegetables, Senbonmatsu Farm yogurtEach item is of high quality and satisfaction is high.I've been to Arashi-no-Yu about three times, and it had a different quality to it than a sauna. The food is of a high quality that you won't find at big-box inns, and it makes sense that they are proud of their cuisine.
