How do I know if have nonenal?
How do I know if have nonenal?
Nonenal, a natural compound created when skin oils oxidize, has a greasy or musty smell. It usually starts after 40, when the skin’s antioxidants decline with age. The catch: you often cannot smell it on yourself. Your nose adapts to it. Other people’s noses do not
Why is it expensive?
Why is it expensive?
- Real fermented kakishibu. Cheap bars use persimmon fragrance or a splash of juice. Kakiyu uses the concentrated tannin extract that actually breaks down nonenal.
- The traditional Japanese method. Made the way kakishibu has been fermented and used for over a thousand years. Most competitors only borrow the word “Japanese”.
- Slow, traditional fermentation. Unripe persimmons are pressed and fermented the traditional way before a single bar is poured. That takes months, not minutes.
- Seasonal and rare. Persimmons ripen once a year, in autumn. One harvest makes a limited number of bars, so every batch is small.
- Still less than your morning coffee. For a problem you actually want gone.
How long does it last?
How long does it last?
4 to 6 weeks per bar with daily use. Each bar is a full 100g, not a mini bar. Keep it on a draining soap dish out of standing water and it lasts even longer.

It is not your hygiene. It is a compound called nonenal
After 40, your skin starts making a new oil called nonenal. That oil is what smells.
Think of a greasy pan. Water runs right over it, and the grease stays. Regular soap does the same thing with this oil. That is why showering more changes nothing.
You cannot smell it on yourself. Other people can.
Why nobody makes it like Kiyora
One harvest.
Persimmons ripen once a year. We press one harvest, the way it has always been done in Japan. Fewer than 50,000 bars. Then we wait for the next autumn. That is what real fruit costs.
Months, not minutes.
The unripe fruit ferments for months. The way Japan has done it for a thousand years. Then it is poured into a glycerin base that holds moisture. The odor comes off. The water stays in.
Everyone wants a shortcut.
Persimmon soap got popular. The copycats came fast. Neon orange bars. Persimmon fragrance. Two for $10. But kakishibu cannot be rushed. We went deep so you never smell it again.
Real results from the first use.
The aging odor gone, confidence back, and skin that feels soft instead of stripped.

What does it smell like
What does it smell like
Quiet and clean, with a faint natural note from the persimmon. It rinses away and leaves your skin smelling like nothing, so it will never fight your perfume or cologne. If you have been burned by soaps that smell worse than the problem, this is the opposite of that.

Is this for men too?
Is this for men too?
Yes. Nonenal does not care who you are. Men over 40 produce it just like women do, often more, and it settles into collars and pillows. Plenty of our bars get quietly placed in a husband’s shower. He will not ask questions. It is just soap.
My skin is sensitive. Is this safe for me?
My skin is sensitive. Is this safe for me?
Kakiyu is free from parabens and synthetic dyes, and the glycerin base is gentle enough for daily use on face and body. As with any new product, if you have very reactive skin, test it on your forearm for a day or two first.
Where should I use it?
Where should I use it?
Once a day in the shower, on the places nonenal builds up the most: behind the ears, the back of the neck, chest, underarms, and the back and shoulders. If you only change one thing about how you wash, wash behind the ears and the back of the neck.
