Yubatake (Hot Water Field)

Yubatake (湯畑), also known as the "hot water field," is one of Japan's most iconic hot spring sources, located in the heart of Kusatsu. This powerful spring gushes over 5000 liters of water every minute, with temperatures reaching above 70°C when it first emerges. The water is channeled through traditional wooden conduits, where it is cooled slightly before being directed to the town's ryokan and public baths. The sulfur-rich scent and the steam rising from the wooden structure create a captivating atmosphere, particularly in the evenings when the area is beautifully illuminated, enhancing the magical, otherworldly feeling of the town.

Around the Yubatake, visitors can explore a variety of charming ryokan, local souvenir shops, and a free foot bath (ashiyu) where they can unwind. A unique feature of the area is the “yunohana” — the mineral-rich deposits left behind by the hot spring water, which are harvested and sold as natural bath salts. In the evenings, Kusatsu's traditional spa culture comes to life as visitors dressed in yukata and wooden sandals leisurely stroll around, adding to the nostalgic and serene ambiance of the town.
