Iwai, nestled in the heart of Gifu Prefecture, is a hidden gem of an onsen area, famed for its untouched beauty and therapeutic waters. The area is encircled by dense, verdant forests, and the penetrating silence is only broken by the gentle rustling of leaves and the soothing babble of the river. The hot springs of Iwai are renowned for their nikkansui (hot spring waters rich in minerals), believed to have immense healing properties, especially for skin ailments and muscle fatigue.
The serene, tranquil charm of Iwai has been appreciated by monks and scholars for centuries, who sought solace and enlightenment amidst its serene landscapes. The area is compact, making it easy to explore on foot, and visitors can immerse themselves in the local culture by visiting the surrounding temples and shrines, or staying in one of the traditional ryokan (Japanese inns) that offer a truly authentic experience.
