What it is
OSAJI Tuning Moisture Soap is a Japanese body soap, 300ml, built on a gentle amino-acid cleanser that washes away excess sebum and dirt without the tight, over-washed feeling. Weakly acidic to match skin, it whips into a cushiony foam with a net and leaves adsorbing hyaluronic acid behind, finishing soft but clean rather than slippery, in an aromatic woody scent.
Why it's different
It uses an amino-acid cleanser (sodium lauroyl methylalaninate), so it cleans gently without stripping or tightness.
Adsorbing hyaluronic acid and biocompatible humectants stay on skin after rinsing for lasting softness, without a slippery film.
The scented Tuning line carries an aromatic woody blend of geranium, lavender, hinoki, myrrh, and yuzu.
Key ingredients

Frequently Asked Questions
Is this authentic?
Yes. We only buy from official retailers and directly from the brands here in Japan. Never resellers, never grey market stock.
We are beauty lovers too, so we know the worry, especially with something you are putting on your face. Authenticity is 100% guaranteed by us.
Why an amino-acid cleanser?
Amino-acid cleansers wash away dirt and excess oil more gently than harsher surfactants, so skin feels clean without the tight, stripped feeling.
Will it leave my skin greasy or slippery?
No. The humectants are chosen to keep skin soft while rinsing off cleanly, so it finishes moisturized rather than slippery.
What does the scent smell like?
An aromatic woody blend, with geranium and lavender over deeper hinoki cypress and myrrh and a fresh touch of yuzu. A refill is available for the bottle.
Do I need a foaming net?
It is not required, but a net gives the fine, cushiony foam the soap is designed for, which makes the wash gentler on skin.
