23,143 reviews, and countingfrom people who swapped their soap and stopped checking how they smell.
How would I even know it is me?
Usually you would not, and that is the problem. From around 40, the oils on your skin start breaking down into nonenal, a greasy, stale note. Your nose gets used to your own scent within minutes, so you stop picking it up. The people standing next to you do not.
Why does one bar cost this much?
Real tannin, not a scent. Cheap bars add persimmon fragrance or a splash of juice. Ours is built on fermented persimmon tannin (kakishibu), the part that actually binds nonenal. Fermenting it takes months, and we make it in small batches. Per wash it still costs less than a coffee.
How many weeks do I get per bar?
Around 4 to 6 weeks of daily use from a full 100g bar. Let it dry on a draining dish between showers and it goes further.
And if it does nothing for me?
Then you get your money back. You have 30 days from delivery. If the smell has not clearly lifted, email help@sawumi.com and we refund you. One email, no forms.
The real reason

It was never about how often you shower. It is one compound: nonenal.

Somewhere in your late thirties or forties, the natural oils on your skin begin to oxidize into nonenal. That is the stale note people pick up on, and it is not a hygiene issue.

Nonenal is oily, so water alone barely touches it. Regular soap washes off sweat and leaves nonenal behind on the skin. That is why it is back by lunchtime even on days you showered twice.

You go nose-blind to it fast. Everyone else keeps noticing.

Fermented persimmon tannin grabs onto nonenal so it rinses away with the lather. That is the whole idea, and most people can tell after the first few washes.

Why the cheap bars do not work
like SAWUMI.

The fruit only comes once a year.

Kakishibu comes from unripe persimmons picked in a short window each autumn. That harvest sets how much tannin exists for the year, which is why we pour in small batches instead of mass runs, and why some batches sell out.

A small factory and a lot of waiting.

The pressed fruit is left to ferment for months, since that is what makes the tannin strong enough to matter. A small family factory then folds it into a base of olive oil, coconut oil and glycerin, so the smell lifts but your skin does not feel tight.

Then the copycats arrived.

Once persimmon soap took off, marketplaces filled with orange bars that smell of persimmon and do little else. Fermentation cannot be faked or rushed. We do it the slow way because that is the only way it works.

Real customers, first-week results.

What they tell us: the smell stopped hanging around, and their skin did not feel stripped.

★★★★★

“I kept noticing a stale smell that hung around even after I’d showered. Switching my usual soap for the persimmon bar made my whole routine feel fresher, and I’m not drowning myself in perfume anymore.”

“My husband showers every single day, but I could still smell something musty on his neck and his shirts. Swapping in this bar was such an easy change, and the light, clean scent suits us both.”

Margaret T.✓ Verified buyer
★★★★★

“I help look after my mum and wanted something that kept her fresh without making her feel embarrassed. It’s just a bar of soap in her shower, so it’s simple, respectful and easy for her to keep using.”

Fermented persimmonTargets the odor

Kakishibu tannin binds nonenal, the compound behind age-related odor, so it washes away instead of being masked.

Olive & coconut oilRich, gentle lather

Cleans away the day’s build-up while leaving mature skin soft rather than squeaky and tight.

+
Green tea extractAntioxidant care

Green tea catechins add antioxidant support for skin that oxidizes more easily as it ages.

+
GlycerinHolds in moisture

Pulls water into the skin and keeps it there, so you step out of the shower comfortable.

Before you order

Everything else you might be asking.

What will I smell like?
Clean, with a faint natural persimmon note while you lather. It rinses off fully, so it never clashes with your perfume or aftershave.
How many showers is one bar?
A full 100g bar gives most people 4 to 6 weeks of daily use. Keep it on a draining dish out of standing water and it lasts longer. That is why most people take the 2 or 4 bar deal.
Does it work for men too?
Yes. Men produce nonenal too, often more of it, and it tends to settle into shirt collars and pillowcases. Plenty of our bars end up shared between partners.
My skin reacts to a lot of soaps. Will this be okay?
It is sulphate-free and made with olive oil, coconut oil and glycerin for daily use on mature skin. Everyone’s skin is different, so patch test on your inner arm first, avoid broken skin, and stop if you get irritation.
Where should I use it?
Once a day in the shower. Focus on where nonenal builds up most: behind the ears, the back of the neck, chest, underarms, back and shoulders. Lather for 30 to 60 seconds, then rinse.
What if nothing changes?
Then it costs you nothing. Use it for up to 30 days from delivery. If you do not notice a clear difference, email help@sawumi.com and we refund you in full.
How does the refill work?
Your first box arrives now with any free bars and gifts. After that, a refill of the bars you paid for ships every month at the same price (1 bar at £23.20 on Buy 1 and Buy 1 Get 1, 2 bars on Buy 2 Get 2). Free bars and gifts are first-order only. You can skip a delivery, change it or cancel anytime from your account or by emailing help@sawumi.com. No fees, no lock-in.
How fast does it arrive?
Orders placed before 11pm are dispatched the same day. Most arrive within 5 to 8 business days, and you get tracking by email as soon as it ships.

This is the best soap. I was being told by my daughter that I smell odd like old musty. I decided to try this soap and have been using it now for about 4 mo. My daughter even asked me what I did different. Did I tell her NO!

My daughter hugged me and pulled away. She said I smelled "odd, like old musty". I was mortified and ordered this soap that same evening. I've been using it for 4 months now, and last week she asked me what's different about me. Did I tell her? NO!

I'm 69 and had started worrying about that "old person smell" I remembered from visiting my aunt years ago. After only a few days of using this persimmon soap, my granddaughter mentioned how fresh I smelled.

Bought it for my husband after 40 years of marriage. He now uses it more religiously than I do. The pillowcase test does not lie.

Sceptical at first, it's soap after all. But within a week the difference on my collars was undeniable. It's the real kaki extract, I checked the label. One star off because I wish the bars were bigger.

Ordered the 3 bar set, one vanished into my sister's handbag within the week. Reordering the 5 pack on subscription, it's cheaper per bar anyway.

The bar itself is lovely, doesn't dry my skin like the carbolic stuff my mother used. Takes a moment to get going in hard water, hence four stars.

Started as mine, now there are two in the shower. The spare room doesn't smell of "grandad's house" when guests stay. That's all I wanted.
