7 min read

Event Overview

The Kawarayu Onsen Yukake Matsuri is a traditional ritual held every year in the early morning of January 20th (the day of Daikan, or Great Cold) at Kawarayu Onsen in Gunma Prefecture. The tradition dates back approximately 400 years, originating as a ritual to celebrate the resurgence of hot spring waters. In front of the communal bathhouse "Oyu," young men dressed in traditional fundoshi (loincloths) splash hot spring water on one another, creating a breathtaking and spirited spectacle known as a "unique festival" that breaks the winter silence.

Highlights & How to Enjoy

The greatest thrill is the sight of hot spring water being splashed amidst the freezing cold. The intense energy of participants divided into red and white teams clashing with hot water, accompanied by rising steam, is a spectacular sight found only during this season. The ritualistic ceremonies and traditional performances are also major highlights. Immerse yourself in the vibrant energy of the hot spring town, enveloped in heat and steam.
