Saga Tara Town
Tara’s bathhouse with sweeping Ariake Sea views and saunas on two floors
The bathing area of Taradake Onsen Kanigoten, an onsen inn in Tara Town, Fujitsu District, Saga Prefecture. The main bathhouse has full ocean views that take in the Ariake Sea and Mount Fugen, and it offers two saunas: the Gravity Sauna, carved from solid spruce, and the Grid Sauna, heated by an AINO heater, the first of its kind in Japan. The deep cold plunge, fed with natural underground water from the Taradake mountains, is built so you can stand in it. Reaching totonou, that state of deep relaxation, on the terrace in the sea breeze is a spectacular experience found only in Tara, “the town where you can see the pull of the moon.”

A weakly alkaline cold mineral spring that rises at the foot of Mount Taradake. Although it is clear, odorless and tasteless, the water feels soft and gentle on the skin. Filling tubs of bluish Towada stone, it gives off a calm, beautiful quality that recalls the sea. In the main bathhouse, with its grand panorama of the Ariake Sea’s tides and Mount Fugen straight ahead, you can soak at leisure while taking in the view. The onsen gently settles the circulation stirred up by the sauna and cold plunge, and it is expected to help with neuralgia, frozen shoulder, chronic digestive ailments, sensitivity to cold and recovery from fatigue. After bathing you stay warm to the core, and the deep relaxation lingers.

A warm room of solid spruce from trees 350 to 400 years old, each piece carved by hand by craftsmen. Wrapped in the scent of wood, you can adjust the heat and steam to your liking with löyly you pour yourself. The moderate temperature lets you stay seated for a long time and slowly work up a sweat. The warmth of the wood and the soft heat envelop your whole body and bring deep relaxation. Gazing out over the spectacular Ariake Sea, you can spend a luxurious, quiet moment alone with yourself.

An original design of spruce precisely fitted into a lattice of 20 mm (0.8 in) slats. The AINO heater, a gentle sauna heater introduced here for the first time in Japan, runs at a relatively low temperature that is easier on the body while still warming you slowly to the core. You can adjust the heat and steam with löyly you pour yourself, and the spectacular Ariake Sea spreads out before you through the lattice. It is an innovative space that offers a new way to enjoy the sauna.

A deep cold plunge on the terrace that you enter standing up. Built so you can sink comfortably up to your shoulders with the Ariake Sea right in front of you, it feels very different from an ordinary cold plunge. It uses soft natural underground water from the Taradake mountains, so the cold rarely feels sharp, and you will want to linger and take it in along with the view. Afterward you step straight out to cool off in the open air in the sea breeze, a rest where you can give yourself over to the sky and the sea.

A deep cold plunge on the indoor side of the ground floor. As on the upper floor, you enter standing up, which makes it easy to immerse yourself fully up to your shoulders. The natural underground water from the Taradake mountains feels soft on the skin, calming the body quickly while letting you savor the pleasure of the water itself. It sits right along the way from the Grid Sauna, so after taking in the gentle heat you can cool down without strain.
