About Okari It starts with a fruit most people throw away.
Every autumn, persimmon orchards drop thousands of unripe, green fruit to the ground. Too bitter to eat, too astringent to sell — most of it is left to rot or composted as waste. We build our soap from it.
That "waste" fruit holds the most powerful version of an ingredient Japan has trusted for over 800 years: persimmon tannin. By rescuing the green fruit the food industry discards, we turn an overlooked byproduct into the heart of your daily ritual. Good for your skin. Better for the orchard floor.
In 13th-century Japan, artisans pressed juice from unripe persimmons and aged it for years to make kakishibu — a natural substance used to waterproof, preserve, and deodorise everything from cloth to fishing nets to lacquerware.
The reason it worked is the same reason it works on you today: persimmon tannin is a large, hydroxyl-rich polyphenol that physically grabs and binds odour molecules — rather than masking them with fragrance or simply rinsing over them. In Japan, persimmon-tannin soap isn't a novelty. It's a mainstream shelf, used for generations. Okari brings that established ritual to the rest of the world.
Here's something the beauty industry rarely talks about honestly: from around age 40, our skin chemistry shifts.
As the body's natural antioxidant defences weaken, the oils on our skin begin to oxidise — producing a compound called 2-nonenal. It's a real, measurable molecule, first identified by researchers in a peer-reviewed study of body odour across ages 26–75.
And here's the frustrating part: 2-nonenal doesn't wash off easily with ordinary soap and water. You shower, and it lingers.
Persimmon tannin doesn't mask and it doesn't just rinse. It works on the actual chemistry of age-related odour, three ways at once:
It captures. The tannin's hundreds of reactive "hooks" bind odour molecules so they can't reach your nose.
It calms bacteria. Persimmon tannin has demonstrated antibacterial activity against the skin bacteria that turn sweat and sebum into smell.
It defends. As a potent antioxidant, it helps limit the very oxidation that creates the odour in the first place.
Capture. Calm. Defend. That's the difference between covering a problem and address
That's the gap conventional products were never designed to close — and exactly the problem persimmon tannin was made for.
We believe getting older deserves products built with honesty and respect — not euphemisms, and not shame. Okari is the meeting point of three things we care about deeply: a centuries-old natural tradition, real published science, and a circular ingredient story that wastes nothing.
A fruit no one wanted. A problem no one talked about. A solution Japan has trusted for 800 years.
That's Okari.
