For those who want to enjoy hot springs in Japan, they have no choice but to be naked! Naked soaking in hot springs is the most natural thing in Japan. Nakedness is the most natural state. In such a nudist camp hot spring world, people face each other坦然 (frankly), cleanse their body and mind, and blend into the natural realm, which is indescribably wonderful. No wonder the Japanese, who regard soaking in hot springs as their greatest love, say that hot springs are their "homeland of the heart."
