Overview (history, characteristics, attractions)
Minakami Onsen is the general name for a hot spring resort in Minakami Town, Tone District, Gunma Prefecture. Surrounded by beautiful valleys carved by the Tone River and its tributaries, the area is characterized by its seasonal natural beauty, with the Tanigawa mountain range as a backdrop. In the past, it developed as a hot spring resort, and since the Meiji period, it has been developed as a tourist destination. The quality of the spring water varies depending on the facility, with some being bicarbonate springs and others being sodium-calcium springs, and many of the hot springs are known for being gentle on the skin and are known as "beauty waters."
The area's appeal lies in its combination of hot springs and activities. Outdoor tourism, such as mountain stream rafting, canyoning, skiing and snow activities, mountain climbing, and autumn leaf viewing, is popular and can be enjoyed throughout the year. With a wide selection of inns, day-trip hot spring facilities, and lodgings with open-air baths, it's also ideal for a staycation where you can relax in the hot spring town.

Things to be aware of (crowds, manners, seasonal precautions, etc.)
-
congestion
Golden Week, summer vacation, autumn foliage season, New Year's holiday, and winter ski season tend to be busy for both overnight stays and day trips. We recommend making reservations in advance and arriving early at popular inns and day trip facilities. -
Hot Spring Manners
Please observe general Japanese hot spring etiquette, such as washing your body in the washing area before bathing, not putting towels in the bath, and avoiding occupying the bath for long periods of time. Some facilities will refuse bathing to those with tattoos, so if you have any concerns, please check in advance. -
Seasonal precautions
In winter, there is snowfall, frozen roads, and chain restrictions. If you are visiting by car, be sure to bring winter tires and chains. In spring, the amount of water for rafting increases due to melting snow, so please check your level and clothing. In summer, the mornings and evenings can be chilly due to the difference in altitude. -
Nature and Mountaineering Safety
The weather in mountain areas such as Mt. Tanigawa is prone to sudden changes, and many trails are for experienced hikers. Be sure to share your equipment, weather information, and an action plan. Consider taking measures to prevent accidents and hiring a guide. -
Cash and equipment
Small restaurants and souvenir shops may only accept cash. Public transportation may have limited service at certain times, so it's a good idea to check your means of transportation back home in advance.
