The town of Kusatsu has flourished around Yubatake. Yubatake is the largest source of hot spring water in Kusatsu, gushing out 4,437 liters of hot spring water per minute at a temperature of 55.7 degrees Celsius. Taro Okamoto supervised the design of the Yubatake area, and Kaoru Mende, a lighting designer, designed the lighting at night.
The spring water flows through seven neatly lined up channels. The hot spring water that flows into the gutter condenses and precipitates over time to produce yunohana (hot spring flowers). The name "Yubata" (hot spring field) is derived from the fact that the hot spring water is used to collect hot spring flowers. After the temperature of the hot spring has cooled down, the hot spring water is sent to the various facilities. The stone pillar and the frame of the hot spring that was used by the 8th Shogun, Yoshimune Yoshimune, are here and tell of the long history of the area.

Origin of Shirahata Souce of Spring
- Founding and Legend: Yoritomo Shrine (Shirahata-source) is located upstream from the hot spring field. It is said that in 1193, Minamoto no Yoritomo (the first shogun of the Kamakura Shogunate) traveled to Kusatsu Onsen on a hunting trip, rebuilt his house in the ribs, and bathed there, which later became an object of worship for Yoritomo himself, according to legend. This source was called "Gozanoyu," and when a shrine was erected, it was patronized by Kusatsu Onsen related persons and hot-spring cure customers as the origin of the opening of the hot spring.
- Renaming to "Shirahata no Yu": The present stone shrine was rebuilt in 1782, and the hot spring was renamed "Shirahata no Yu" in 1887 from "Shirahata," the banner of the Genji clan.
- Kusatsu-cho Designated Cultural Property: Yoritomo Shrine is designated as a Kusatsu-cho Designated Cultural Property as a historical site for the tradition of the opening of Kusatsu Onsen and the belief in hot springs.

History of Yutaki's Lantern
Yudaki's Lantern is a historic stone lantern donated in 1830 by the Ise Taiyo-kochu people. This lantern was used as a night light for the Fudo Hall, which was located beside the Yubatake hot spring. Later, as Kusatsu Onsen developed, the Yudaki lantern became a symbol of the hot spring resort.
Characteristics of Yudaki Lanterns
Yudaki's Lantern overlooks the hot spring fields of Kusatsu Onsen and is a stone lantern with an old-fashioned appearance. Yudaki's lantern offers a spectacular view of the hot spring fields, especially when illuminated at night, providing an unforgettable sight for visitors.
Reasons to Visit
Yudaki's Lantern is a precious place that offers not only a beautiful view of Kusatsu Onsen, but also a sense of the history of onsen culture. The Yudaki lanterns are also a source of artistic inspiration, as the Japanese painter Ryuko Kawabata is famous for her painting "Reisen-dera (Origin of the Reisen)," which was inspired by the steam from the May rain.
