Reimagining the art of "Creation"

Tsuchiya Kaban is starting a new chapter of craftmanship.

Our goal is to create "Endearing Products".
Upholding that goal means evolving our handcrafted
products to meet today's consumers.

We have decided to use Mylo™, a next generational,
high quality material derived from mushroom mycelium.
We are one of the early pioneers working
with the Mylo™ material.

Combining innovative mushroom leather with
Tsuchiya Kaban's storied history of
Japanese craftsmanship will birth new,
unseen ideas and creations.

Creating "Endearing Products" 
with new ideas

The idea of what an "Endearing Product"
means is different from person to person.
The job is a creator is to keep searching for
an ever evolving consumer base.
This is not just reflected in our product's functionality or design
but also with the fundamental materials
that is at the core of handcrafting our products.

Our journey with Mylo™ started with us talking to Bolt Threads,
a cutting-edge biotechnology company in the US.
Our strong belief in Bolt Threads' mission of
"From the Earth, for the Future"
led us to form a partnership together.

Meet Mylo™

Mylo™ is made from mycelium, the underground root structure of mushrooms, an infinitely renewable resource. Mycelial microfibers provide a soft feel with fine texture. Mylo™ was designed to have flexibility, making it highly versatile to be used in a variety of products.

The mycelium is grown in less than two weeks with mulch, air, and water, allowing Bolt Threads to scale supply.


Tsuchiya Kaban has begun product development with Mylo™ mushroom leather.
