Kanagawa Yokohama City

"Yokohama Aoba Onsen Kirari Bettei" is a day-use hot spring facility in Aoba Ward, Yokohama City, Kanagawa Prefecture. It is carefully maintained as a quiet environment for elementary school students and older, allowing adults to relax at their leisure. The weakly alkaline natural hot spring "Bijin no Yu," which springs from 2,000 meters underground, combines a cleansing effect that leaves the skin smooth with excellent heat-retaining and moisturizing benefits. In addition to the atmospheric open-air bath fed directly from the source and surrounded by bamboo groves, the facility also features a high-concentration carbonated spring that is among the largest in the area, a powerful auto-löyly sauna with triple blowers, a deep cold bath, and an Iwaburo sauna area called Onnetsubō.

Hot Spring & Bath Information

Yokohama Aoba Onsen

TypeNatural Hot Spring

Flow-through

A weakly alkaline golden natural hot spring that springs from 2,000 meters underground. Because bicarbonate soda helps emulsify the skin and leaves it smooth, it is known as a "beautifying bath," and it is also rich in metasilicic acid. In addition, the salt content forms a salt film on the skin after bathing, delivering excellent heat-retaining and moisturizing effects, making it a "warming bath" as well. The outdoor "source spring bath" is provided with heated free-flowing water, allowing you to enjoy the superb hot spring to your heart’s content while looking out over the beautiful and tranquil bamboo grove.

A spacious three-tier auto-löyly sauna located inside the large bath area. At regular intervals, the triple blowers unleash a powerful blast of hot air as the double hot-air löyly system activates, quickly raising the perceived temperature and driving an explosive, deeply satisfying sweat. The room, wrapped in the warmth of wood, has high ceilings and even includes rental urethane mats. The strong heat activates the whole body’s metabolism and refreshingly blows away everyday stress and fatigue.

A deep cold plunge bath installed right in front of the sauna room, boasting a maximum depth of 110 cm. It is deep enough to fully submerge your body, and the crisp cold water instantly tightens up a body heated to its limit in the sauna. The texture on the skin is extremely smooth, delivering a pleasantly intense cooling experience. After the cold bath, you can enjoy outdoor air bathing while gazing at the beautifully lit green bamboo grove, and sink into the ultimate tottonou state and deep relaxation.
