Unzen Onsen, developed in the 19th century as a summer retreat for foreigners, is located in the heart of the Shimabara Peninsula in southern Nagasaki Prefecture. Nestled in a national park rich in nature, this unique onsen town is situated at an altitude of 700 meters, with numerous hotels and inns dotting the mountainside.
At the heart of the town lies an area known as "Jigoku" (Hell), characterized by its high-temperature hot springs. Visitors can stroll along well-maintained paths in this area, engulfed in a strong sulfuric smell and surrounded by billowing white steam, creating a landscape reminiscent of hell itself. This striking scenery is a product of the energy from magma reservoirs beneath the sea bed, making it a distinctive spot to visit while exploring Unzen.
The hot springs at Unzen Onsen are piped in from these hells, offering a strongly acidic sulfuric bath. These waters are known for their skin beautification properties, fatigue recovery benefits, and relief for neuralgia and joint pains. A relaxing and leisurely bath in these waters is the perfect way to gently soothe the weariness of travel.
