Step 2 · How would you like it?
If the people closest to you don't notice, it's free.Use it daily for 30 days. If your partner, your kids or your friends haven't noticed a difference, email us for a full refund. You keep the soap. No need to send it back.
"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."

Will it work on me?
If you shower every day and still notice a stale scent by evening, on your pillowcase or your collars, that's the pattern Kohaku is made for. Use it daily on the back of your neck, behind your ears, your chest and underarms. If it doesn't work for you, the guarantee above covers you.
How will I know it's working, if I can't smell it on myself?
- Night 1: check your pillowcase in the morning.
- By day 7: your collars still smell like nothing at the end of the day.
- Weeks 2–4: someone close to you notices before you say anything.
Why not just buy a cheap $3 persimmon bar?
You can. Here's what the cheap bar doesn't come with: a gentle, unscented glycerin base with shea butter and olive oil made for mature, sensitive skin, green tea added alongside the persimmon, a lathering mesh bag with every bar, free shipping, and a money-back guarantee if nobody notices a difference.
And it still works out to less than $1 a day.
How long does one bar last?
About a month of daily use. Each 100g bar ships in its own lathering mesh bag. The bag makes a rich lather from a small amount of soap and lets the bar dry between uses, so it doesn't go soft and melt away.
Low stock notice
We sold out seven 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.

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.
