Kojigoku Onsenkan

Nestled in the serene mountain valleys of Unzen, a gentle plume of white steam rises softly, signaling a hidden gem for relaxation. This is Kojigoku Onsenkan, a day-trip hot spring facility perfectly harmonized with its peaceful natural surroundings. It has become a beloved destination for visitors from both near and far, all seeking the healing embrace of its rich, soothing waters.

What makes Kojigoku Onsenkan truly special is its direct use of the hot spring water gushing right behind the building. The milky, silky flow of the onsen water is kept fresh by minimizing exposure to the outside air, allowing bathers to fully relish its cloudy texture and tender warmth. The onsen is served in an indulgent, constant flowing manner, so as you soak, you feel the gentle power of the earth’s blessings seep deeply into your body. The temperature is carefully set between 40 and 43 degrees Celsius, thoughtfully adjusted for a comfortably long soak that leaves you refreshed but never overwhelmed.

Kojigoku Onsenkan serves as a beloved haven not only for travelers but also for locals seeking a moment of everyday tranquility. After exploring the surrounding nature trails, visitors can stop by to wash away fatigue in the authentic sulfur-scented waters without the need for an overnight stay. This facility offers the perfect blend of casual accessibility and genuine hot spring atmosphere, where the natural bounty of Unzen invites you to rejuvenate your mind and body in a deeply refreshing experience.
