- Gentle, unscented glycerin bar for mature, sensitive skin — no cover-up perfume
CHOOSE YOUR SUPPLY
"After about 40, the skin makes more of a compound called Nonenal — it's the real reason a faint, stale scent lingers even after you shower, because ordinary soap can't break it down. Persimmon tannins actually neutralize it at the source instead of masking it, and in a gentle, nourishing base I'm comfortable recommending Kohaku for daily use — even on mature, sensitive skin."

Low stock notice
We sold out three times last year and the last restock took seven weeks — persimmon is harvested seasonally, so we can't simply order more. If you'd rather not gamble on it being here next month, subscribing reserves your bar from every batch before it goes on general sale. Cancel any time.
The odor has a name: nonenal
Around 40, skin begins producing nonenal — the compound behind that faint, persistent scent that returns hours after a shower. It isn't about hygiene, and scrubbing harder won't fix it. It's chemistry — and chemistry has an answer.
Persimmon breaks it down at the source
In Japan the scent has a name — kareishu — and a remedy trusted for generations: persimmon tannin, paired with green tea. Ordinary soap covers the odor. Kohaku neutralizes it where it starts, wash after wash.
Unscented — because fresh needs no disguise
No fragrance, no masking perfume. A rich, creamy lather with green tea, vitamin E and shea, gentle on mature skin. One bar. One month. Simply fresh.

I kept washing and it kept coming back within a few hours. A friend from Osaka told me about persimmon soap and I ordered the same day. Two weeks in, I stopped checking. That's the best way I can put it — I just stopped thinking about it.

I didn't recognize the scent on my own pillowcase, and that honestly scared me. This bar is the first thing that ended it instead of perfuming over it. My sheets smell like nothing now. Nothing is wonderful.

I'd started keeping my distance from people without realizing I was doing it. Six weeks with this bar and that habit is gone. I hold hugs longer now.

My wife ordered it for me without saying much. Three weeks later she told me why. I wasn't offended — I was grateful. I've reordered twice since.

Perimenopause changed a lot of things, including how I felt about myself by evening. I was skeptical of a soap making promises like this, truly. But it does exactly what it says — nothing to mask anything, just fresh skin.

Fifty-eight and I figured this was just part of getting old. It isn't. The musty scent is gone — and my skin's softer too.

Bought it after reading about nonenal — finally a name for the thing I'd quietly worried about for a year. It lathers rich, doesn't dry my skin, and I feel properly clean the whole day.

I gave one to my sister and we compared notes like schoolgirls. Both fresh, both a little smug about it. Wish the three-pack had been my first order.

Noticed it on my shirt collars first. Regular soap did nothing. This did — within the first week. Collars are just shirts again.

Unscented is what sold me. I didn't want to trade one smell for another. You step out of the shower smelling like clean skin, full stop.

My wife noticed that “old guy” scent on my pillow and collars before I did. A month on, she says it's gone. Nothing else touched it.

Ordered one bar to test, came back for the three-pack. It's the difference between covering something up and it simply not being there.

The bar itself is beautiful — amber, like a gem — and it lasts the full month with the little mesh bag. But mostly: it works. I don't spray perfume just to leave the house anymore.

My daughter hugged me and said 'you smell like you again.' I cried a little. That's the review.

Skeptical at first — it's a bar of soap. But the persimmon thing is real. Collars stay fresh, no more evening funk. Repurchasing.

Gentle enough for my skin, which reacts to everything. No itching, no tightness, and the freshness actually lasts past lunchtime.

Frequently asked questions
Everything you need to know about Kohaku, nonenal, and the guarantee.
Does it actually work?
+
Persimmon tannin has been used in Japan for generations to neutralize nonenal — the compound Japanese researchers identified behind so-called aging odor. We pair it with green tea in a gentle glycerin base. It doesn't mask odor with fragrance; it breaks it down at the source, every wash.
How fast will I notice a difference?
+
It works from the first wash — most people notice the difference within the first week of daily use: on skin, on collars, on the pillow. One bar lasts about a month.
Is this a medical product?
+
No. Kohaku is a cosmetic soap — it deodorizes and cares for skin. It doesn't treat or cure anything. If a change in body odor is sudden or unusual for you, it's worth mentioning to your doctor.
How long does shipping take?
+
Orders ship within 24 hours, then typically arrive in 7–10 business days with tracking. Free shipping on every order.
What's your return policy?
+
You're covered by our 30-day money-back guarantee. Use it daily, and if you don't feel fresher and more confident, reach out and we'll refund you — no hassle.
