Kusatsu Onsen, nestled within the scenic mountains of Gunma Prefecture, is one of Japan’s most prestigious and prolific hot spring resorts. Its roots trace back over a millennium, with its restorative waters having a legendary reputation for their healing properties. Kusatsu’s thermal waters, known as yubatake (hot water field), are renowned for their high sulfur content, which gives the waters their distinctive, therapeutic qualities.
The cultural depth of Kusatsu Onsen is as impressive as its natural beauty. The time-honored practice of yumomi (water cooling), where locals cool the hot spring waters with large wooden paddles while chanting traditional songs, is a mesmerizing spectacle. Wandering around the charming town, with its traditional wooden inns (ryokan), delightful eateries, and quaint shops, is a journey into the timeless heart of Japan.
