[Great location and charming owner couple]Right in front of the Tazawako ski resort, Mizusawa Onsen, whose spring quality is comparable to Nyuto Onsen, and atop a hill overlooking the spectacular view of Lake Tazawa. A wonderful location surrounded by a white birch forest.This is a small guesthouse run by a dandy, smiling husband and a wife who is very service-minded and serves a lot of elaborate and loving home-cooked meals.[Local production for local consumption and careful home-cooked meals that are kind to the body]The local produce and local cuisine from his wife's hometown, Niigata, are just amazing. A variety of home-cooked dishes carefully prepared using fresh ingredients such as rice (Akitakomachi), vegetables, mushrooms, meat, and fish. Both dinner and breakfast had a rich variety of items and felt luxurious. Simple, low-salt seasonings using dashi stock, handmade seasonings, and the acidity of fruits are gentle on the body, bring out the goodness of the ingredients, and are good for your health. The Inaniwa udon that I had at the end of dinner was also more flavorful and delicious than the ones I had at a famous restaurant in Akita in the past.[Exclusive hot springs with plenty of hot springs]There are two indoor baths with natural hot spring water. This is really amazing. There are two types: one that is large and has a normal temperature, and one that is hot enough for one person, and there is so much hot water that it accumulates at the bottom of the bath. It is a beautiful skin bath that will make your skin smooth. It is a completely private style where you hang the tag you are using at the entrance when you take a bath, but since there are only a few rooms, you can enjoy the best hot springs by yourself without having to wait for a long time.[The building is designed with the users in mind]The building is non-smoking (there is a smoking area for one person), and the first floor is a living/dining room with a bar where you can enjoy breakfast and dinner, as well as Akita sake, beer, wine, and whiskey for a fee. The second floor has guest rooms, bathrooms, washrooms, a shared refrigerator, smoking room, and a gathering space where you can enjoy comics, etc. The third floor is also a guest room. Shampoo and body soap are provided in the bathroom and sink, and toiletries, washing machines, drinks, sweets, etc. are available for a fee, but they are available in the gathering space, and are perfect for long stays such as skiing in winter or climbing Mt. Komagatake in Akita. It's a very friendly inn.*Towada-Hachimantai National Park is located in the middle of one of the world's largest primeval beech forests and white birch forests. For those who can accept an environment rich in ecosystems such as wild animals and insects, and for those who do not need hotel-like facilities, I think this is the best inn in terms of hot springs, quality of food, hospitality of the owner couple, and cost performance.
