Overview

Meito-no-Yu Azumaso is a traditional hot spring ryokan in Onogawa Onsen, Yonezawa, Yamagata. The ryokan has welcomed travelers since 1789 and continues the feeling of a classic hot spring retreat, with source-flowing water, tatami rooms, Yonezawa food, and views toward the Azuma mountain range or the Onogawa hot spring town.

This is a good stay when you want a quiet onsen town atmosphere, deep source-flowing baths, Yonezawa beef, seasonal local cuisine, and a more personal ryokan feeling. Onogawa Onsen has more than 1,000 years of hot spring history, and Azumaso keeps the focus on bathing, rest, and regional food rather than resort-style entertainment.

Accommodation

You can choose from main-building Japanese rooms, special rooms with source-flowing hot spring baths, and the separate Azumaen annex for pet-friendly stays. Main-building rooms face either the Azuma mountain range or the Onogawa hot spring town, with tatami flooring, seasonal flowers, and a kotatsu in winter.

The main-building 12.5-tatami room is the largest corner room in Azumaso and works well when you want more space. The 10-tatami room is the standard Japanese room, with a sitting area and views toward either the mountains or town. The 8-tatami room is a comfortable choice for one or two people. These rooms include Wi-Fi, TV, refrigerator, washbasin, warm-water washing toilet, safe, hair dryer, yukata, towels, toothbrush set, tea set, and tea sweets.

For private hot spring bathing, choose one of the two special rooms with source-flowing baths. The third-floor special room has a 19.5-tatami Japanese-Western layout, two semi-double beds, futon bedding for larger use, Wi-Fi, and a semi-open-air hot spring bath. The second-floor special room has the same 19.5-tatami Japanese-Western layout, two semi-double beds, Wi-Fi, and a private indoor hot spring bath.

If you travel with a pet, Azumaen sits across the road from the main building. It has five rooms with source-flowing indoor hot spring baths. Room types include 17-tatami, 14-tatami, 10-tatami, and 8-tatami Japanese rooms. These baths do not have showers, so you use the main building’s large public bath when you want a shower. Pets stay in the same room, and you need to bring pet items such as food, dishes, sheets, mat, blanket, and cage or lead.

Dining

Dinner highlights Yonezawa and Yamagata flavors. You can enjoy Yonezawa beef, seasonal vegetables, local mountain ingredients, river fish, carp dishes, and regional home-style cooking prepared as a Japanese meal. Yonezawa beef can appear in dishes such as sukiyaki, shabu-shabu, or steak depending on your plan.

The ryokan’s local dishes include Yonezawa carp simmered slowly in a sweet-savory sauce, hiyajiru made with local vegetables, uchi-mame, kukitachi greens, and frozen konjac, plus seasonal dishes using mountain vegetables, mushrooms, fruit, and local produce.

Breakfast focuses on rice and simple regional flavor. You can enjoy rice made with Tsuyahime and Koshihikari from contracted farmers, polished twice for a refined texture, along with local radium eggs, tofu, fresh seasonal vegetables, and other Japanese breakfast dishes.

Meals are served in the dining hall or a private dining room. If you stay in the Azumaen annex with a pet, dinner and breakfast are usually served either in your room or in a pet-friendly private dining room, depending on the day and arrangement.

Onsen and Wellness

Azumaso uses source-flowing Onogawa Onsen water. The ryokan mainly blends the 80°C No. 4 source and the 35°C No. 5 source by season, so you can soak in naturally flowing water at a comfortable temperature. The water has high salt content despite the mountain setting, and it also contains sulfur and radium components.

The large public bath faces the garden through wide windows and has a slightly deeper tub, so you can stretch out and let the heat settle into your body. Bathing is usually available from afternoon until the next morning, except during special maintenance.

You can also reserve a private bath. It is not too large, has handrails, and works well when you want a more personal soak with family or someone who prefers easier bathing. Advance reservation is required, and plan conditions may differ, so confirm the details when you book or check in

The water is known for warmth, skin moisture, sulfur cleansing qualities, and deep heat retention, especially in winter.

Guests with Tattoos

For the smoothest stay, choose a room with a private source-flowing bath or reserve the private bath when available.

Facilities

Azumaso gives you a traditional ryokan setting with a polished entrance, garden views, public bath, private bath, dining hall, souvenir corner, and in-room massage by reservation. The courtyard was created with stones brought from a mountain owned by the family, and it changes with the season: butterbur sprouts after the snow melts, cherry blossoms in spring, hydrangeas in the rainy season, and snow-protection scenery in winter. You can see the garden from the entrance, corridors, and dining area, and it is lit at night.

The courtyard also has a footbath and a pond with koi. Near the entrance, you can buy local sweets, Onogawa mist, pickles, soft drinks, and local beer, or take time after your bath before returning to your room. Colorful yukata rental is available at the front desk, so you can change and walk through the hot spring town in a more relaxed style.

For practical support, Wi-Fi is available in main-building rooms and in the five Azumaen annex rooms, though some older rooms do not have Wi-Fi. The ryokan is fully non-smoking inside, with smoking areas near the entrance lobby or rear parking entrance. Parking is available, and there is no shuttle service, so you arrive by car, taxi, or local bus.

Activities

You can spend your time slowly inside the ryokan with the baths, private bath, footbath, garden, local food, and massage. The atmosphere suits you when you want to rest, read, soak, walk in yukata, and let the hot spring town set the pace.

Around Onogawa Onsen, you can enjoy seasonal walks, town scenery, local sweets, and the nature around the Otaru River. The area is known for cherry blossoms in spring, fireflies in summer, autumn leaves, and snowy winter scenery.

Yonezawa also gives you strong cultural and food experiences. You can explore Uesugi-related history, Yonezawa’s castle-town atmosphere, local sake, Yonezawa beef, and nearby sightseeing while returning to Onogawa for hot spring bathing.
