Description
Authentic Japanese carbonated bath salts by Bathclin — the "Cool" summer edition of the beloved Kikiyu (きき湯) line. Mineral-rich fizzing granules with a menthol finish that leaves skin feeling cool and refreshed after a hot day. A medicated bath (quasi-drug), about 12 soaks per bottle. Ships directly from Kobe.
What it is
Kikiyu (きき湯) is one of Japan's most trusted bath brands, launched in 2003 and modelled on the mineral hot springs of Nagayu Onsen in Ōita. This is its summer "Seiryō" (清涼 — "cool and refreshing") carbonated line: the same fizzing, mineral-rich granules, finished with menthol so that once you step out of the bath your skin feels cool rather than hot and flushed. In Japan it's classified as a 医薬部外品 (quasi-drug / medicated bath additive).
In Japanese homes, a cool-type bath is a summer ritual: you still soak — because a warm bath actually helps you shed heat and sleep better in humid nights — but the menthol finish stops the bath from leaving you overheated afterward.
How it works
Drop the measured granules into the tub and they fizz, dissolving carbon dioxide and hot-spring-style minerals into the water. The carbonation and minerals support the warm-bath effect that helps circulation and eases tired shoulders and lower back. The menthol and cooling agents then deliver that signature after-bath coolness on the skin — the reason this variant exists for summer rather than the standard warming Kikiyu.
Key benefits
- Cool, refreshed after-feel — menthol finish leaves skin cool instead of flushed.
- Carbonated mineral soak — fizzing granules dissolve hot-spring-style minerals into the water.
- Eases tired shoulders & lower back — the warm-bath + carbonation effect on a heavy summer day.
- Crisp mint fragrance — a clean, cooling scent for the bathroom.
- ~12 baths per bottle — measured with the included scoop, easy to dose.
- Made in Japan — genuine Bathclin Kikiyu, the same line sold in Japanese drugstores.
Who is this for?
Recommended for anyone who still loves a proper soak in summer but hates feeling overheated afterward. Ideal after a hot commute, sport, or a humid night when you want to cool down and sleep. Also for fans of Japanese onsen-style and carbonated bathing looking for a seasonal variant.
How to use
- Fill the tub with hot water (about 150–200 L, standard Japanese bath).
- Add one scoop (approx. 30 g) of granules using the included measure.
- Stir briefly and let it fizz and dissolve.
- Soak as usual and enjoy the cool menthol after-feel.
Tip: for a stronger cooling finish in high summer, run the bath slightly cooler than in winter.

FAQ
Does a "cooling" bath mean cold water?
No. You still take a normal warm bath — the warmth helps your body release heat and relax. The difference is the menthol finish, which leaves your skin feeling cool and refreshed instead of hot once you step out.
How many baths per bottle?
About 12, using one scoop (~30 g) per standard Japanese tub.
Is it safe for sensitive skin?
It's a widely sold quasi-drug bath additive, but menthol is strong for some people. Start with a smaller dose and stop if you notice irritation.
Is this the same product sold in Japan?
Yes — genuine Bathclin Kikiyu from the summer "Seiryō" cool line, shipped from Kobe.
Will it fit a Western bathtub?
Yes. Dosing is by water volume; a standard Western tub is similar to a Japanese one. Adjust the scoop slightly for a larger tub.
From Natalia, in Kobe
People are always surprised when I tell them Japanese households keep taking baths through the summer — but in a humid Kobe July, a proper soak is one of the best ways to actually cool down before bed, because it helps your body shed heat afterward. The trick is the "cool" bath salts. I keep a bottle of the minty Kikiyu on the shelf from June: same familiar carbonated fizz, but you climb out feeling refreshed instead of sticky. It's a small, very Japanese piece of summer that most people outside Japan have never tried.
