The carbonated mineral spring feels just like sparkling carbonated lemonade on your body. That is where the spa name comes from. In fact, the spring water was packed in bottles to be sold as lemonade during the Meiji era. It is said that the spring water is effective at curing weak stomachs and heartburn. It received the Incentive award at the expo in Germany in 1881. The spring water of Ramune Ginsen is of excellent quality. Carbon dioxide gas is absorbed into your body, which dilates the blood vessels. It is effective for people recovering from fatigue, lower back pains, and skin irritation. This mildly acidic spring water makes your skin smooth, therefore, it is referred to as a “rejuvenation spa” or a “beautiful skin spa”.
The spring water is initially clear and colorless, but eventually becomes oxidized and the color turn to murky gold. This proves that it is highly energizing.
