[Medicinal Nagayu Hot Tub Classic] Nagayu Hot Tub is a bicarbonate bath additive originating from Nagayu Onsen in Oita Prefecture, one of Japan's leading national hot spring resorts. Nagayu Onsen boasts exceptional water quality, making it ideal for natural therapy. Aiming to capture this quality, Nagayu Hot Tub was developed in collaboration with Taketa City, Oita Prefecture. Enjoy the benefits of Nagayu Onsen in the comfort of your own home.
[Differences from the Hot Tub Series] Like the regular Hot Tub series, Nagayu Hot Tub is a bath additive made with a unique formula that efficiently produces bicarbonate ions by combining baking soda and citric acid in tablet form. Designed to more closely resemble the spring quality of Nagayu Onsen, it continuously emits fine carbon dioxide bubbles, which dissociate into bicarbonate ions and hydrogen ions in the water. The concentration is maintained for 24 hours, allowing for reheating.
[How to Use Nagayu Hot Tub] Dissolve 3 tablets in approximately 160 liters of lukewarm water (36°C-41°C) (approximately 4 tablets in approximately 200 liters). We recommend the "bicarbonate bath method," which involves soaking in bicarbonate-containing water for at least 15 minutes. Even lukewarm water warms the body from the inside out, and the benefits continue even after bathing. The pH of the natural carbonated springs of Germany's therapeutic hot springs and Oita's Nagayu Onsen is neutral, at 6.7 to 7.1. Carbon dioxide cannot exist at a neutral pH, so most of the carbon dioxide is converted into bicarbonate ions, which are thought to enhance the bathing and cleansing effects of the natural carbonated springs and warm the body.
[Suitable for those with sensitive skin and babies] Nagayu Hot Tub produces gentle, colorless water without any added additives. It neutralizes chlorine and contains no fragrances or colorings. The concentration lasts for 24 hours, allowing family members who join later to enjoy the warming effects by reheating the water. Furthermore, the water from Nagayu Hot Tub neutralizes chlorine, resulting in a neutral pH. This results in gentle skin irritation and a soft feel. It can even be used by people with sensitive skin and babies.
[Active Ingredients] Sodium bicarbonate, sodium carbonate. [Other Ingredients] Anhydrous citric acid, vitamin C and sodium, glycine, and three other ingredients. *This product does not contain sulfur, which can damage bathtubs and boilers.
