Ariake Sea Hot Spring

📅Reservation Required

Ariake Sea no Yu is an accommodation-type hot bath facility located in Tara Town, Fujitsu District, Saga Prefecture. It features two types of saunas for men and women: the Gravity Sauna, crafted from solid spruce wood aged 350-400 years and hand-finished by artisans, and the Grid Sauna, equipped with Japan's first low-impact heater 'AINO'. Guests can control the heat with self-administered löyly. The standing cold plunge bath, 130-150cm deep, uses natural underground water from the Tara Mountain range, providing a quick full-body cool down. The large public bath offers a panoramic view of the Ariake Sea and Mount Unzen, with a bath made of bluish Towada stone reminiscent of the sea. The facility also includes the mildly alkaline Taranodake Onsen, a lounge with complimentary drinks, and Panasonic's meditation room MUROOM. Both overnight and day-use options are available, offering a supreme healing experience surrounded by breathtaking views and tranquility.

♨️Hot Spring Information

♨️
Taranodake Onsen
Natural Hot Spring
A mildly alkaline cold mineral spring that wells up from the foot of Mount Tara. It is colorless, odorless, and tasteless, yet the water feels soft and gentle on the skin. The bath filled with water in a bluish Towada stone tub evokes the tranquility and beauty of the sea. You can soak leisurely in the large bath with a panoramic view of the Ariake Sea's tides and Mount Unzen. The hot spring gently adjusts the increased blood flow from the sauna and cold plunge bath, potentially benefiting neuralgia, frozen shoulder, chronic digestive pain, sensitivity to cold, and fatigue recovery. After bathing, you will feel warmth from the core of your body, with deep relaxation continuing.
