A New Story, Woven from Scallop Shells.

STORY

Nothing Should Go to Waste.

A Way of Life Passed Down Through Generations in Shimokita.

Gathering fallen grains of rice.
Turning driftwood into firewood.
Finding purpose even in a single scallop shell.

In a land shaped by a harsh natural environment, resourcefulness was more than wisdom—it became a way of life.

A way of life deeply rooted in this region and carried forward to this day.

物尽其用

Giving Everything Its Fullest Purpose.

We believe everything has a purpose.

And that nothing should be left without the chance to fulfill it.

Discover its potential.

Make the most of it.

Pass it on.

These are the three principles that guide KOHARUTO.

Our First Step

From the gifts of this land,
to innovation for the world,
and onward to future generations.

We began with something that had long been considered spent:
scallop shells nurtured by Mutsu Bay.

We saw new potential in what others saw as waste.
And from that possibility, "ORIUMI" was born.

This is KOHARUTO’s first step.

Carrying the gifts of this land
into a new era.

And bringing
the value of our region to the world.

ORIUMI

Sustainable Fiber, Born from Local Resources.

ORIUMI is a sustainable fiber made from scallop shells—an abundant local resource that has long remained underutilized.
