Ariake Sea Hot Spring
Ariake Sea no Yu is an accommodation-type hot bath facility located in Tara Town, Fujitsu District, Saga Prefecture.

Hot Spring Information
Taranodake Onsen
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.

A warm space crafted from solid spruce wood aged 350-400 years, hand-carved by artisans piece by piece. Surrounded by the scent of wood, you can control the heat and steam to your liking with self-administered löyly. The moderate temperature allows for prolonged sitting, drawing out sweat gradually. The warmth of the wood and gentle heat envelop the body, bringing deep relaxation. Enjoy a luxurious moment of quiet reflection while gazing at the stunning view of the Ariake Sea.
Grid Sauna
An innovative design with spruce wood precisely arranged in a 20mm grid pattern. Equipped with Japan's first low-impact sauna heater 'AINO', it provides a gentle warmth that penetrates deeply while minimizing strain on the body at relatively lower temperatures. You can adjust the heat and steam with self-administered löyly, and enjoy the breathtaking view of the Ariake Sea through the grid. This space offers a new experiential way to enjoy saunas.

Located on the terrace right after exiting the sauna, it features a system where soft underground natural water from the Tara Mountain range is constantly replenished. It provides a full-body cool down up to the shoulders, with a comfortable chill that soothes the heated body.
