Inyo-ryu Kempo Katete-jutsudo (Sakyo Ward, Kyoto City) held their New Year's winter practice on January 7, 2024, in the Nakanoshima area of Arashiyama Park in Ukyo Ward, Kyoto City. Approximately 400 people, mostly children, entered the Katsuragawa River and braved the cold to pump their fists.

It has been held every year in Arashiyama for more than 50 years to train the mind and body, and students from 3 to 80 years old gather from Kyoto and Shiga. When he stepped into the Katsura River near Togetsukyo Bridge, it was so cold that he let out a cry, but when the practice began, he cheered up by shouting "Ei" and began punching with his left and right fists.
An 11-year-old boy who participated for the first time said with a smile, ''When I move my body, I don't get cold anymore.I guess I've grown up with the strength to endure.''
