Exploring Kusatsu Onsen - Tourist Attractions, Hot Springs, and More

Hot springs (onsen) are so prominent in Japan that there are even areas known for primarily being an onsen resort district. These places exist in nearly every prefecture of the country and offer seemingly countless hot spring bath options for tourists to choose from.

For the prefecture of Gunma, the Kusatsu Onsen stands as the most popular hot spring resort, which, interestingly, also serves as a wonderland for ski enthusiasts during the winter season.

Yubatake, which literally translates to mean “the field of hot water” in English, is one of the most iconic landmarks of Kusatsu Onsen. In fact, it serves as the hot spring resort district’s main source for all of the onsens it houses.

Capable of supplying a recorded output of about five thousand liters per minute, Yubatake stands among the most productive hot spring sources of Japan.

Numerous ryokans (traditional Japanese inns) and charming shops are scattered around the area. As such, the nearby streets are usually filled with tourists and locals clad in yukata robes and geta sandals.

Mount Shirane

Mount Shirane, also known as Kusatsu-Shirane or Shiranesan, refers to an area located just beyond the outskirts of Kusatsu Onsen which features a series of volcanic peaks.

als take a trip to Mount Shirane to hike during the spring, summer, and autumn seasons. Come winter, the place turns into a haven for ski and snow sports enthusiasts.

The hiking routes of Mount Shirane range from easy to highly difficult walking paths, but the chairlifts and ropeway of the Kusatsu Kokusai Ski Resort offers an easy solution for those who want to skip the trails.

Tourists are advised to at least do the easiest trail of the area which goes from the Shirane Resthouse to the Yugama Crater Lake. This route can be done in ten minutes or less and features a paved trail that makes the hike all the more comfortable. Once at the end of the trail, a baby blue-colored lake and breathtaking mountain ranges can be found.

Sainokawara Park

Sainokawara Park, or Sainokawara Koen, is located several hundred meters away from the central town of Kusatsu Onsen. The area houses several hot springs and walking trails for visitors to enjoy and explore.

One of the most popular points of interest of the park is the Sainokawara Rotemburo, which is composed of two gender-separated outdoor onsen baths that can comfortably accommodate up to a hundred people each.
