A Guide to Netsunoyu and Kusatsu Onsen’s Iconic Show, Yumomi

If this is your first time visiting Kusatsu Onsen, the attraction that you have to visit is Netsunoyu (熱乃湯). It was one of the public bathhouses in Kusatsu Onsen until the early 20th century. But since 1968, it has been transformed into a theater-like facility to introduce visitors to Kusatsu’s tradition and performing arts. In 2015, a major renovation was completed to the building giving it a Taishō period appearance.

What Is Yumomi?

At Netsunoyu, Kusatsu Onsen’s iconic performance, Yumomi (湯もみ), is held six times a day. It is one of the main reasons why tourists visit Kusatsu Onsen.

Yumomi is the name given to the process of stirring high-temperature hot spring water with large wooden paddles. This is a part of the hospitality of Kusatsu Onsen’s bathhouses to bring down the hot spring’s temperature without diluting it with cold water. That way, the customers can enjoy the full medical benefits of Kusatsu’s hot spring!

Yumomi is said to start in the Edo period. Since 1960, it has now become a unique show which entertains tourists. The 20-minute show isn’t all about stirring the onsen. It first starts off with a short introductory film with Engish subtitles about Kusatsu Onsen, followed by Kusatsu’s traditional dancing (草津節の踊り) before the Yumomi performance.

After the performance, the audience is invited to stir the hot spring (although currently suspended due to COVID-19). A commemorative photo will also be taken with you holding the 180 cm long, 30 cm wide wooden paddle. And as proof of your effort, you will even receive a Yumomi certificate at the end!

Tips:
☛ Purchase your Yumomi performance ticket as soon as possible. Tickets might be sold out for the session you want to attend.
☛ Arrive at least 15 minutes before the show starts so you can sit in the front row on the first or second floor, which offers the best view.
☛ The seats in the front row on the first floor are the ones closest to the performers. Photos of the show can be taken easily from this row.

The Yumomi-Kun Show (ゆもみくんショー)

Instead of women, if you want to see young guys performing Yumomi, check out Netsunoyu’s calendar HERE to see when the Yumomi-Kun Show is on!

The young men performing in the special Yumomi shows are all Kusatsu’s soccer players who aim to become professionals. With their strong athletic built, the show is going to be more exciting for many!
