Jujutsu is a traditional Japanese martial art that involves techniques for unarmed attack and defense. Used historically by samurai, it is considered the root of judo and aikido. Today, it remains widely recognized as an effective self-defense method against dangerous situations. To promote and develop jujutsu among women, the "Full-Power Jujutsu Dojo in Swimsuits" was established. This dojo aims to teach proper jujutsu techniques to help women protect themselves from dangers such as crowded trains and walking alone at night, while also strengthening their bodies. A unique feature of this dojo is that all participants train in swimsuits, culminating in a bikini jujutsu championship event.
