A thousand years of
Japanese purity
in a single bar.

For over a millennium, Japanese craftsmen have used kaki shibu — persimmon tannin — to waterproof, preserve, and purify. Ancient farmers rubbed their hands with persimmon juice after long days of labour. Samurai used it on their armour. The tradition endured because it works.

Tsūki distils this lineage into a cold-pressed cleansing bar. No synthetic fragrance. No harsh detergents. Just the raw power of persimmon tannins binding and eliminating odour molecules at a molecular level.

Three ingredients.
One ancient formula.

No fillers. No compromise.

Persimmon Tannin
柿渋 · Kaki Shibu
The active core. Binds odour-causing bacteria and neutralises them on contact. Anti-inflammatory, astringent, and deeply cleansing.
Cold-Pressed Olive
オリーブ油 · Olive Yu
Moisturises without stripping the skin's natural barrier. Rich in squalene and polyphenols that leave skin supple and balanced.
Activated Charcoal
炭 · Sumi
Draws impurities from deep within pores. Amplifies the purifying action of the persimmon tannins for a complete cleanse.

How to use Tsūki

Wet the bar with warm water
Allow the persimmon to activate. The tannins release best with warmth. Take a moment. This is the beginning of the ritual.
Lather directly on skin
Work into a rich lather. Focus on areas of concern — underarms, feet, anywhere odour forms. The tannins begin binding immediately.
Let it sit for 30 seconds
Unlike ordinary soap, Tsūki works on contact time. A brief pause allows the persimmon to fully neutralise, not just mask.
Rinse and feel the difference
No residue. No perfume trail. Just clean skin that stays odour-free for hours. Store your bar on a dry soap dish to extend its life.
