Why Visit Kusatsu Onsen
Kusatsu Onsen ranks among Japan's three legendary hot springs, nestled at 1,200 meters in Gunma Prefecture's volcanic mountains, where over 32,000 liters of highly acidic, sulfur-rich water surge from Mount Shirane each minute to feed the iconic Yubatake hot water field at the town's heart.[1][3][4] This geothermal powerhouse, praised by 19th-century German doctor Erwin von Baelz for its therapeutic powers against all ills except lovesickness, powers 19 free public bathhouses alongside ryokans, charming alleys lined with crafts shops, and performances like the paddle-stirring Yumomi ritual.[2][3][5] Year-round appeal spans winter skiing, summer hiking in Sainokawara Park, and illuminated night strolls, though spring cherry blossoms and autumn foliage elevate the scenery.[1][3][6]
