Turn your bath at home into a natural hot spring. HAA for bath's 4 secrets.
Mixing natural ingredients processed by hand by artisans.Spend relaxing time with the gentle bathwater of "HAA for bath".
"Beppu yunohana", precious hot spring essence made by hand from the Edo period.
The main ingredient of "HAA for bath" is yunohana, or mineral deposit from hot springs, which has been made in Beppu from nearly 350 years ago. These crystals only react to the blue clay found in the mountains of Beppu. By combining Beppu yunohana components with alkaline hot spring components in a delicate balance, we have achieved a bathwater quality rich in natural minerals, while being smooth and soft to the skin.

Let your body feel lasting warmth with our bathwater rich in minerals.
Adding “HAA for bath” to your bath results in milky, thick bathwater. The mineral components in the bathwater gently covers your skin and prevents your body heat from dissipating, resulting in lasting warmth after bathing.

No use of sulfur which damages bathtubs
Sulfuric components, which cause damage to bathtubs, have been removed from “HAA for bath” during its production. Enjoy the feeling of bathing in a natural hot spring at home.

Fragrance-free so everyone can use it without worrying
We haven’t used any fragrances in order to make our product easy to use for everyone, including babies over 3 months of age, pregnant persons, and elderly persons.

朝のTIMEを見て興味を持ちすぐお願いしました。
入浴剤は好きで、かなりアレコレ使ってますので、それなりに毎月の出費も大変です(笑
でも、求めている効果を全て求めるのは中々難しいので、その時々で使い分けてます。
こちらを使ったのは3回だけですが、最初の衝撃は言葉にならない位でした。
温泉に浸かったときを思い出す程で、かなり久しぶりに朝までぐっすり眠れました(*^^)
定期購入も考えています。
いいものに出会えて良かった! -
