It is a historical fact that the first Tokugawa Shogun Ieyasu, the eighth Shogun Yoshimune, and the tenth Shogun Ieharu, had hot spring water brought from Kusatsu Onsen to Edo Castle in today's Tokyo in barrels for bathing. Throughout history, Kusatsu Onsen has been visited by numerous feudal lords, military commanders, and literary figures.
Located in the center of Kusatsu Onsen resort, the hot spring source called Yubatake gushes over 4,000 liters of hot spring water every minute. The Yubatake, which literally means "field of hot water", is a symbol of Kusatsu Onsen and the site is beautifully lit up after dark. Here, you can smell the intense odor of sulfur and watch billowing clouds of steam coming off from one of the largest natural springs in Japan. The hot spring water, which is an extremely hot 55 degrees Celsius when it comes out of the ground, passes through a series of wooden channels and is then sent to individual Ryokan inns in the town, cooling it along the way. The sinter accumulated here is a popular souvenir called "Yu-no-Hana (Hot Water Flowers)".
