Okudaira Onsen Yushinkan is a day-use hot spring facility located in the lush mountain countryside of Minakami, Gunma Prefecture. Nestled in the mountains of the historic Mikuni area and surrounded by the soothing sounds of a flowing stream, it is a popular place for both local residents and visitors to enjoy an authentic Japanese hot spring experience.
Surrounded by beautiful scenery throughout the year, Yushinkan offers a relaxing escape where visitors can enjoy the natural environment while taking their time in the hot springs.
The greatest attraction of Yushinkan is its abundant natural hot spring water. The spring is classified as an alkaline simple hot spring and is also known as a “beauty-enhancing” hot spring because of its gentle feel on the skin.
The soft water leaves the skin feeling smooth and refreshed after bathing. The hot spring has traditionally been enjoyed for relaxation and is said to be beneficial for conditions such as nerve pain, joint discomfort, fatigue, and general health maintenance.
The facility uses 100% natural hot spring water, with some baths offering a direct-flow experience. The dedicated source-fed bath is not artificially heated or recirculated, allowing guests to experience the water in a more natural state.
At around 30°C, this bath is relatively cool compared with a typical hot spring and is particularly popular as a refreshing cooldown after using the sauna.
Yushinkan features a variety of bathing facilities, including a large communal bath, open-air bath, jacuzzi, herbal baths, and sauna.
The spacious indoor bath provides a comfortable place to relax while looking out at the surrounding scenery. Guests can take their time in the warm water while enjoying a peaceful view of the mountains and countryside.
The rock-lined open-air bath offers an even stronger connection with nature. Fresh green foliage in spring and summer, colorful autumn leaves, and snowy winter scenery create a different atmosphere with every visit.
Seasonal herbal baths are also popular. Special baths featuring ingredients such as yuzu citrus, apples, and Japanese iris fill the water with pleasant aromas and add another dimension to the bathing experience.
The low-temperature sauna is designed to be gentler on the body. Spending time there and gradually working up a sweat can be a relaxing way to unwind and refresh yourself.
Yushinkan offers much more than bathing facilities. Its spacious 120-tatami-mat relaxation hall provides plenty of room for guests to rest, enjoy a meal, take a nap, or simply spend time at their own pace.
Private rooms are also available, making it possible for families and groups of friends to relax in a more secluded setting.
The facility also has banquet spaces that can accommodate events such as family memorial gatherings and welcome or farewell parties. A large venue is available for groups of up to 160 people.
The building is designed with barrier-free accessibility, making it suitable for visitors of a wide range of ages and mobility needs.
The on-site restaurant serves dishes made with ingredients from Minakami and the surrounding region.
Popular choices include handmade soba made with locally produced flour, catfish dishes, and kamameshi, a traditional rice dish cooked in an individual pot. The cooking emphasizes the natural flavors of the ingredients and offers a simple, comforting taste of local mountain cuisine.
The café also serves sweets made with locally grown fruit and wheat, making it a pleasant place to stop for a dessert or drink after bathing.
Inside the facility is Irikoi Yokocho, a farmers’ market where visitors can purchase fresh local vegetables, processed foods, handicrafts, and other regional products.
It is a convenient place to find souvenirs while discovering some of the agricultural and craft traditions of the Minakami area.
For additional relaxation, Yushinkan also offers services such as traditional hand massage, beauty treatments, and massage chairs. Combining these services with a hot spring bath can make for an especially relaxing visit.
The river flowing in front of Yushinkan provides opportunities for playing in the water during the summer. The clear stream and surrounding greenery create a refreshing environment that can be enjoyed by both children and adults.
Visitors can also feed carp raised in hot spring water in the pond in the garden. This simple activity adds a charming touch to a relaxing visit and is particularly enjoyable for families.
