A gentle alkaline simple thermal spring. With its high pH it has the slippery feel of Japan's beauty-water family, soft on the skin. It carries a notable 181.6 mg/kg of metasilicic acid, which leaves a thin silica film for noticeably smoother skin afterwards. The water is reheated and chlorine-disinfected, then served as free-flow.

About

Aomoriya counts five separate bathing spots across its grounds, among them an indoor bath scented with hiba wood, an outdoor bath that seems to float over a pond (guests call it Ukiyu, 浮湯), and a foot bath overlooking the property. The water is kakenagashi, kept flowing straight from the source, with a smooth, faintly silky feel. The hotel itself is built like an old Aomori village, with horse-drawn carriages on its paths and Nebuta festival decorations throughout. Staff, known as kaccha (かっちゃ, a local word for mom), serve regional Aomori dishes, and a nightly festival show with food stalls takes place in a central square.

Aomoriya Hoshino The rotenburo is awesome! It feels like lying in a lake with trees all around, pure bliss! But there are always people there, so you can only get some privacy right after the daytime break. The water is cool, it feels slippery because of the pH 9.3. There are almost no minerals. The temperature is +41. There is a mizuburo and a sauna. The floor inside is very slippery❗️ because the shower uses the same slippery onsen water. There is no point in booking a room with its own onsen because the water there is tap water... and they charge an extra €200 for that😅💸 Also, I was disappointed that the room had tatami everywhere, but you sleep on a mattress🥺 why not a futon??????😢 We were the only ones in yukata... everyone else was in pajamas or regular clothes. The park is beautiful! Definitely worth a walk. There are lots of people at the hotel non-stop

940. Aomoriya by Hoshino Resorts, Misawa, Aomori (pt.2) ★★★ About the onsen: 1. Outdoor area. It looks incredible. A large oval bath by a pond, with trees growing around it. Depending on the season, the object in the center of the pond changes, for example in winter there is a nebuta there. In April there was an artificial cherry blossom, and round lanterns in pink tones float in the pond itself. It is very striking and makes you want to stay as long as possible. The atmosphere is completely different during the day and in the evening, which gives a wider range of visual experiences and enjoyment. 1.1. Main oval bath. The water is clear, with a soapy effect. Temperature 41. 10.04.2026 11.04.2026

940. Aomoriya by Hoshino Resorts, Misawa, Aomori (pt.1) ★★★ Stayed overnight. No day-use bathing. For guests staying overnight, free access to the Motoyu onsen is available, with a shuttle running there. A large complex, like a little town inside. Lots of cool decorations with nebuta. There are plenty of different activities, from simple ones to ones that require booking: performances, ponies, crafts, taverns, workshops, arcade games, quizzes, and more. A lot of Japanese staff. There is not much direct activity in terms of service, but if you ask for help, they pay attention and help solve the issue fully. I needed to take a taxi for several hours after check-in and visit a few onsen nearby along the onsen road. The staff called the taxi company, and they were not able to provide a car continuously for several hours, so the staff themselves suggested it and then booked separate taxi reservations for each onsen at the right times, so I could travel between them comfortably. For food, I had dinner and breakfast, and everything was buffet style. It was comfortable and I liked it, even though I do not especially like that format in general. A top-class place with an incredible bath. It is worth the trip on its own, and if you are choosing accommodation in Aomori, it will be hard not to choose this place again, despite the strong competition in the prefecture. 10.04.2026 11.04.2026

Visited a place from my bucket list. The north delivers, and winter is already here. A reasonably priced ryokan that features a Nebuta sauna and Nebuta in the rotenburo. Inside everything is very cozy, all in wood, two baths at 42 and 39 degrees. Outside there's a rotenburo that extends into a small lake, but you can't go into the lake. Outside there's also a sauna entrance and a small cold bath. They feed you a buffet with all sorts of food, even ice cream. There's also a paid show — highly recommend, it's like a mini matsuri. *First photo is from the internet but the Nebuta figure is there on-site.
