How to Use Japanese Bath Salts
Fill your bathtub up with warm water. Open one sachet; the salts may have a strong fragrance when you first open them, this will soften as they dissolve. Pour the entire sachet into your bath and mix it around until the powder dissolves. Immerse yourself in the tub and soak for at least 20 minutes. The bath salts will help the water to retain its heat. When you are finished simply towel dry, there is no need to rinse after soaking.
