1 of 6 in Gunma Prefecture

Kusatsu Onsen (草津温泉) is a scenic mountain hot spring resort in Gunma Prefecture, sitting 1,200 meters above sea level. Known for its natural beauty, it offers winter skiing, summer hiking, and year-round relaxing hot spring baths. Located along Japan’s Romantic Road, it's a perfect escape for nature and wellness lovers.

The town has been famous for centuries thanks to its abundant high-quality spring water, said to heal all ailments except lovesickness. Its popularity grew even more when German physician Erwin von Baelz, who served Japan’s imperial court in the 1800s, praised its therapeutic effects. With its charming atmosphere and relaxing waters, Kusatsu Onsen remains one of Japan’s top hot spring getaways.
