A spectacular infinity open-air bath that merges with the Pacific, and natural onsen water
Akazawa Day-Trip Onsen is a bathhouse for day visitors in Ito, Shizuoka. Its greatest draw is the large infinity open-air bath, overwhelmingly open, where the surface of the water seems to run straight into the horizon of the Pacific. You can sink into natural onsen water, a chloride spring that holds its heat well, and take in a vast panorama of sky and sea. There is also a sauna walled entirely in glass with views of the ocean, as well as a spot for cooling off in the open air with a sea breeze and a spectacular view. After bathing, you can spend the whole day at ease in the Umi no Nekorobi Lounge, stocked with some 6,000 manga, or in the restaurant.

A large infinity-style open-air bath spread out before a panorama of the Pacific, and a spacious indoor bath with a jacuzzi and a reclining bath. The natural onsen water is a chloride spring that holds its heat well, so you do not cool down quickly after bathing, and with the sound of the surf as your soundtrack you can enjoy the ultimate sense of immersion, as if melting into the sea and sky.

A dry sauna with a panoramic view of the Pacific through huge floor-to-ceiling windows, and a steam room where dense, soft steam wraps the whole body. Far-infrared heat reaches slowly to the core, and a pleasant sweat comes as you gaze at the blue of sea and sky. The moisture-laden steam rarely feels stifling and leads you into deep relaxation. Fresh water overflowing close by quietly pulls the flushed body taut, and then you unwind into the Pacific sea breeze.

A warm room kept at a comfortable temperature, where you stay clothed and warm your body through to the core. By encouraging a slow sweat at a low temperature, it keeps the strain on your body down, and you can expect a boost to your metabolism and a detox effect. Between baths or sauna sessions, it is a soothing place to rest at your ease.
