A yubatake is a facility where the source of hot spring water is poured over the surface of the ground or into a wooden gutter to collect hot water flowers, an ingredient of hot spring water, and to control the temperature of the water.
They also serve to remove harmful concentrations of hydrogen sulfide through aeration.
In some cases, the harmful sulfur content of the water causes the installation of exclusion fences and warning signs.
 Yubatake exist in many hot spring areas where hot water flowers are collected, and in Kusatsu Onsen in Kusatsu-machi, Gunma Prefecture, they have become a local landmark and tourist attraction.
The Kusatsu Onsen in Kusatsu Town, Gunma Prefecture, is a local landmark and tourist attraction. Kusatsu and Unzen are some of the most famous places.
