Overview

Onyado Toho is a hillside hot spring ryokan in Aizu Higashiyama Onsen, overlooking Aizuwakamatsu and the surrounding mountains. You stay in one of three buildings — Tower Building, Suzakutei, or Main Building — with 160 rooms in total and views of the castle town from selected rooms. The stay is built around wide scenery, Aizu culture, buffet dining, and large open-air baths that feel open to the sky.

Aizu Higashiyama Onsen has a long history of around 1,300 years, and the hot spring area has been connected with poets, artists, and historical figures over time. At Onyado Toho, you can enjoy that history in a larger ryokan setting with easy access to Aizuwakamatsu sightseeing.

Accommodation

You can choose from premium-floor Irodori rooms, Japanese rooms, Western rooms, large group rooms, and a special Japanese-Western room. Room styles include tatami layouts, bedded rooms, rooms with city views, mountain-side rooms, and larger layouts for family or group travel. Most room types include a bath, washbasin, and warm-water washing toilet, while the large 32-tatami group room does not have a bath and uses the public bath instead. In-room baths use heated water, not hot spring water.

The Irodori Japanese room with two beds sits on the top floor of Suzakutei and faces the castle town. It has 14.5 tatami mats, two Simmons beds, a 50-inch TV, bath, washbasin, and warm-water washing toilet. The Irodori mountain-side Japanese room has 12 tatami mats, table seating, a 50-inch TV, and Aizu Hongo ware washbasin details. Both Irodori room types are non-smoking, including electronic cigarettes.

The Main Building Japanese rooms are quieter mountain-side rooms with 8, 10, or 16 tatami layouts. The single room in the Main Building is a compact Western-style room with a unit bath, warm-water washing toilet, and smoking-permitted setting. The special Japanese-Western room sits on the top room floor of the Tower Building and combines a 12.5-tatami Japanese room, adjoining room, and bedroom.

Dining

Dinner is served at the buffet restaurant Agaransho, where you can enjoy live cooking from the open kitchen. Tempura, nigiri sushi, teppanyaki dishes, and other freshly prepared items are served in front of you, so the meal feels lively and easy to enjoy. The restaurant interior uses Aizu lacquerware and Aizu cotton as design motifs, and window-side seating looks out toward the castle town through a wide panoramic window.

Breakfast is also served buffet style at Agaransho, with a focus on Aizu and Tohoku flavors. You can enjoy Aizu rice onigiri with fillings such as salmon, tuna mayonnaise, Aizu vegetable miso, and spicy cod roe; mochi with toppings such as kinako sugar, anko, grated daikon, and zunda; plus Kitakata-style morning ramen with soy sauce flavor.

If you have food allergies, please plan carefully. Meals are mainly buffet style, and the same kitchen, cooking tools, serving utensils, and washing areas are used across menu items, so allergen cross-contact cannot be fully prevented. Allergy-specific menus and ingredient-answer support are not provided, but you may bring safe retort foods or tableware with advance notice.

Onsen and Wellness

The main bathing experience centers on two large open-air observation baths: Sora no Yu and Tanagumo no Yu. Both sit on the west side of the Tower Building’s third floor, on a hill around 300 meters above sea level, with views across the Aizu Basin and toward the mountains beyond. During the day, you can look over Aizuwakamatsu; at night, you can soak under the sky and city lights.

Sora no Yu has indoor bathing, two terraced open-air baths with different depths, and a circular open-air tub that reaches out 11 meters above the ground. Bamboo, wind sounds, birdsong, and night lighting shape the atmosphere. This bath area also includes a mist sauna and security boxes.

Tanagumo no Yu has an indoor bath and three terraced open-air baths. The upper level gives you full-body soaking with a wide view, the middle level works for half-body bathing, and the lower level is designed as a reclining bath where you can lie back and look up. This bath area includes a dry sauna and security boxes. The two bath areas switch between men and women in the morning, though the switching schedule may change.

The spring quality is sulfate spring water. Listed indications include cuts, burns, chronic skin disease, muscle pain, joint pain, frozen shoulder, bruises, chronic digestive issues, hemorrhoids, sensitivity to cold, fatigue recovery, and health promotion. The baths use both free-flowing and circulation systems; when circulated, the water may be heated and diluted for temperature control and supply.

You also have Sora no Michi, the bath approach inspired by the phases of the moon, plus a women-only powder room with dryers, brushes, and skincare items. After bathing, you can rest at Sesenagi, the post-bath lounge, where Hokkaido haskap water and ice candy are available during service hours.

Guests with Tattoos

If you have tattoos, you cannot use or enter the public bath areas.

Facilities

Onyado Toho gives you plenty of space to enjoy your stay between meals and baths. The lobby lounge offers hot coffee, oolong tea, soft drinks, and ice during set service hours, making it a comfortable place to pause before check-in, after sightseeing, or before dinner. The shop sells Aizu souvenirs such as local sweets, Kitakata ramen, Aizu lacquerware, akabeko folk toys, pickles, miso, Aizu cotton goods, drinks, and snacks.

You can stay connected with free wireless LAN throughout the building and in all rooms. The ryokan also has an arcade and karaoke, conference space, meeting rooms, luggage storage, a safe at the front desk, daily housekeeping, and elevator access. Parking is available, with space for standard cars or large buses, plus an adjacent parking area.

The bath-side facilities add to the stay, especially the women-only powder room, Sesenagi post-bath lounge, mist sauna, dry sauna, security boxes, and the moon-themed Sora no Michi walkway leading toward the baths. These spaces make the onsen experience feel more complete than a simple bath visit.

Activities

Inside the ryokan, you can enjoy the open-air baths, saunas, post-bath lounge, buffet dining, karaoke, arcade, and TOHO Treasure Hunting, a free indoor puzzle-style activity. The ryokan also works well for group stays, meetings, and celebrations thanks to its large rooms, banquet spaces, and meeting facilities.

Around Aizuwakamatsu, you can explore Tsuruga Castle, Iimoriyama, Nanukamachi, and other historic areas using the city loop buses Haikara-san and Akabee. These buses connect key sightseeing spots and help you experience the castle town without needing to drive everywhere.
