The Masters Behind the Denim?
Work Only with The Best.
The best cotton in the world deserves the best mills in the world.
And this one has three.
Yamachu Spinning
Yarn Production
They don’t just spin yarn—they engineer it.
They use a 7x8 thread technique, which is next-level craftsmanship.
- Seven fibres twisted together.
- Eight fibres twisted together.
- Then combined into a 56-fiber thread.
The result? A yarn with controlled irregularity, just like vintage denim.
Hand-picked Zimbabwe cotton needs a master spinner.
Yamachu lets the fibre’s natural strength shine.
Each batch of cotton is allowed to breathe before spinning. 24 hours in a climate-controlled room. Old-school ring spinning, not open-end shortcuts. This means a stronger, smoother yarn.
Zimbabwe cotton’s long fibres mean it can be spun finer.
1. Fine yarn = high-tension weave = legendary fades.
They deconstruct old jeans to understand vintage yarn. Then, they recreate that magic—better. Balance is key. Just enough slub for texture, not too much for breakage.
2. Low-speed spinning = high integrity yarn.
This is why your denim lasts. Without the right spinning, the best cotton is wasted.
Yamachu honours the fibre with precision and patience.
Sakamoto Dyeing
Indigo Rope Dyeing
They have blue blood running through them.
They were Japan’s first mechanized rope-dyeing house in 1892 and have been perfecting it since.
Indeed, without Sakamoto, Japanese denim wouldn’t exist.
Compromise? They'd rather dye.
Indigo takes time. Multiple dips, each one oxidized between, so the colour sets deep.
The true skill is controlling the white core.
Deep indigo on the outside, undyed inside = perfect fades.
Not all indigo is the same. Sakamoto controls shades down to the finest variations.
They invented Japan’s first continuous dyeing machine. That’s innovation in action.
Sustainable dyeing before it was trendy. Electrolysed water system, less chemical runoff.
They mastered both synthetic and natural indigo. Traditional aizome (Japanese indigo dyeing) meets modern rope dyeing.
Consistency is everything.
Every yarn gets the exact same treatment, every time.
Indigo fades, but Sakamoto’s legacy won’t.
They set the standard for Japanese denim dyeing.
Yamaashi Orimono
Weaving
They’ve been weaving denim for over 80 years. That’s generations of knowledge, passed down.
- Vintage shuttle looms.
- No mass production.
- Every inch of fabric is slow-made for perfection.
Selvedge denim masters live here.
Zimbabwe cotton + shuttle looms = the dream team.
Strong, yet soft.
Tough, yet breathable.
Woven at a lower tension for an authentic, vintage feel.
Their machines move at a fraction of the speed of modern looms.
Why rush perfection?
The shuttle loom creates a continuous weft thread.
That’s what gives selvedge denim its durability.
Inspectors check every yard by hand. If it’s not perfect, it doesn’t leave the mill.
They don’t know how to compromise.
