What secrets does this combination hold?
Theurapeutic onsen bathing has been cherished since the Edo period in Japan.
Many people have experienced firsthand the health benefits of onsens.
Have you ever wondered, "Aren’t all onsens the same?"
In truth, the mineral composition of each onsen varies, making no two springs identical.
“Therapeutic onsen pairing” invites you to enjoy hot springs in pairs.
This amplifies their complementary effects—where "1 + 1" isn’t just 2, but 3 or even 4!
THERAPEUTIC ONSEN RESEARCH
Historically, during the Edo period in Joshu (now Gunma Prefecture), it was recommended to follow a soak in the highly acidic waters of Kusatsu Onsen with the milder waters of Sawatari Onsen or Shima Onsen. In those old days, people discovered that this combination improved their skin condition. This traditional practice is considered the origin of therapeutic onsen pairing.
When it comes to therapeutic onsen pairing in Beppu City, two classic courses stand out for their effectiveness and popularity among vistors. They are:
① Shampoo & Rinse Course
Acidic sulfur spring → Mildly acidic chloride spring
② Ultra Smooth Skin Course
Neutral sulfur spring → Mildly alkaline bicarbonate spring
Beyond these, other scientifically-backed pairings have been introduced, alongside hand-picked combinations curated by onsen enthusiasts. With countless possibilities still waiting to be discovered, why not explore and create a pairing that’s uniquely yours?
