Kusatsu Onsen (草津温泉) is a picturesque mountain hot spring resort located 1,200 meters above sea level in Gunma Prefecture. Known for its stunning natural surroundings, the resort offers a range of activities throughout the year, from winter skiing and summer hiking to year-round hot spring baths that provide relaxation and rejuvenation. Situated along Japan’s Romantic Road, Kusatsu Onsen is a perfect destination for those seeking a peaceful retreat in nature, combined with the benefits of traditional wellness experiences.

The town's fame dates back centuries, primarily due to its abundant supply of high-quality spring water, which locals have long believed to possess healing properties for nearly every ailment, except lovesickness. Kusatsu’s reputation grew further in the 1800s when German physician Erwin von Baelz, who served Japan’s imperial court, extolled the therapeutic effects of the hot springs. With its serene atmosphere and soothing waters, Kusatsu Onsen continues to be one of Japan's most popular hot spring destinations, offering a tranquil escape for both Japanese and international visitors alike.
