There is a knack to bathing in a hot spring, so choose a bath that suits your physical condition. A "standing bath" is expected to improve blood flow as water pressure is evenly distributed over the entire body. A "lying bath" improves blood and lymph flow and is said to be effective against arteriosclerosis, high blood pressure, mental fatigue, and insomnia. A "cascading bath" is suitable for people who suffer from stiff shoulders or back pain. The silky bath promotes blood circulation with the massage effect of superfine microbubbles, and the cleansing effect removes sebum from pores. It is expected to moisturize and warm the skin, and the generation of negative ions also has a relaxing effect.

Also, in hot spring areas where the water temperature is generally high, an increasing number of inns are equipped with baths of different temperatures, such as hot, moderate, and lukewarm. After soaking in hot water for a few minutes to steam the whole body, cooling down the heated body in a low-temperature bath increases metabolism, promotes sweating and the excretion of waste products, and can also help reduce obesity, neuralgia, and stress. Shikisai Ichiriki in Bandai Atami Onsen, Fukushima Prefecture, offers a "warm bath" with water directly from the source that can be enjoyed in the open-air garden bath and large public bath.
