Yumomi (湯もみ) is a traditional method of cooling down hot spring water to bathing temperature by stirring the water with large wooden paddles. The process is accompanied by the singing of a local folk song.
A yumomi performance for tourists is held daily in the Netsunoyu building next to the yubatake. The performance includes a yumomi and dance performance, and several people from the audience have the opportunity to partake in yumomi. The building was recently rebuilt and reopened to the public in late April 2015.
