"A small and cosy hotel. Comes with hot spring voucher for you to enjoy the bath. About 10mins walk to the street with restaurant. Plenty of parking available and is free. Staff will use a translator to explain all the details of the hotel."

"i wouldnt hestitate staying here if i was passing through to see mt.aso again. granted there was only 1 other guest in my room which made it comfortable/quiet so i wouldnt be sure with a packed house. the receptionist "mama" was so cutesy!!!"

"As for the food, both dinner and breakfast, we were very satisfied with both their quality and quantity. If I were to make a complaint, it would be that the cottages that are far from the public bath, restaurant, and front desk can take a long time to get to (the cottage we stayed in was in the very edge area), but the location was good and overall we were satisfied with our stay."

"I arrived around 8pm, took a shower and checked out around 6am the next day. It was a short stay but I had a good sleep."

"Nice n quiet place."

"To soak in the world's best carbonated spring at the Lamune Onsen in Nagyu Onsen, I stayed one night at the Daimaru Ryokan. 1. The Daimaru Ryokan has a history of over 100 years, built along the Serikawa River. The exterior is understated, but the interior exudes the air of a classic luxury inn. At the front desk sat a woman in a kimono and heavy makeup; she was not young, but her beauty was still evident. In Japan, good inns are often run by beautiful women. The hotel rooms were nice, with views of the Serikawa River in full bloom. The hotel also displayed many artworks, giving it a strong old-money feel. 2. The main reason for staying at the Daimaru was to soak in the carbonated spring. The hotel's onsen is also carbonated, but the water temperature reached 46 degrees Celsius, and the carbonic acid had dissipated. Later, Daimaru Ryokan built the "Lamune Onsen" a few hundred meters away. The open-air bath there has a water temperature of only 32 degrees Celsius, with abundant carbonated bubbles. Soaking in it feels like soaking in soda water—a tingling, numbing sensation, with your whole body enveloped in bubbles—a truly magical experience. There's also a sauna nearby; you can steam and then soak, which is incredibly relaxing. 3. Staying at Daimaru comes with a perk: free access to the "Lamune Onsen." To get to the "Lamune Onsen" from Daimaru, you walk along the Serikawa River, passing a crab-shaped open-air pool—a spot where the hot spring flows by the river. People can bathe for free, but they must not wear clothes or intentionally expose themselves. I thought no one would use it, but surprisingly, some did. There's a warning sign on the roadside near the onsen entrance: watch out for a cat crossing the street, as a cat often crosses the road to visit the onsen. 4. Bottled hot spring water can be purchased at both the onsen and Daimaru Ryokan. Many hot springs in Japan have drinkable water, but most don't taste as good as Nagayu Onsen; its water is truly refreshingly sweet. The meals included in the one-night stay are also quite good."

"a very kind owner couple. thank you for your help."

"I originally booked this hotel for the convenience of going to Mount Aso, but I didn't realize that the volcano had been closed for some time. This hotel is located in a far outskirts, but the facilities are very good and the environment is beautiful. When we arrived, the owner was very enthusiastic and explained. We didn't understand Japanese, so he translated to us on the phone. The hot spring is in another room, and there were not many guests that night. Our family could enjoy one hot spring room, and everyone was very satisfied. The room is large, with one bed per person and complete facilities. The breakfast the next day was Western-style and very rich. The bakery owner who couldn't finish it packed it for us and took it away. No food was wasted. Very good service.  There is also an astronomical telescope on the grassland. Unfortunately, it was very cloudy that night, so there was no chance to see the stars. No wonder the hotel has "Galaxy" as its name. I think you can see the Milky Way in the sky when the weather is good. I hope to have the opportunity to come back next time. Fortunately, Mount Aso suddenly opened again after checking out, and we actually saw the volcano!"

"The sky and air of Kuju, the green of the trees, the mountain range visible in the distance, the cozy atmosphere, the warm hospitality, the delicious food—a wonderful auberge. A place where you can reset your mind. A place I love."
