NO SIGN × Osu no Sushi｜Knife Case Development Case Study (Leather OEM)
From Miyazaki to the world:
OEM development of knife cases.
NO SIGN,
together with the sushi school "Osu no Sushi,"
has developed a knife case using Miyazaki Wagyu leather.
In this article,
we introduce the background and process of this OEM product development, built from the ground up.
■ Background of the leather OEM development
Osu no Sushi is a sushi school based in Aoshima, Miyazaki Prefecture,
that shares Japanese culture with international visitors.
Focusing on the sushi experience,
they engage in activities to convey the essence of Japanese culture,
including pottery, sake, fermented foods, agriculture, and marine sports.
As they provide people from all over the world with
"an experience they can take home,"
the concept of
"Could we turn the sushi chef's own tools into a product?"
led to the start of this leather OEM development.
■ Purpose of product development
For a sushi chef, a knife is
not just a tool, but "the skill itself."
- Ability to carry it safely
- Durability even in environments involving frequent travel
- Design that embodies the Japanese aesthetic
They required a knife case that meets these criteria,
combining both functionality and brand identity.
■ Leather OEM design (Development points)
In this OEM development,
we based our design on the following points:
- Use of Miyazaki Wagyu leather
- A structure that can safely store multiple knives
- Design considering stability during transport
- A design aesthetic mindful of global expansion
It is designed not just as a leather product,
but as a "product used in the professional field."
■ Reflecting the professional perspective
The development of this product also incorporated
the insights of Mr. Mitsuhiro Tsumoto, known for his
"Ultimate Blood-letting" technique for managing fish freshness.
After he personally reviewed the samples,
- How the knives fit
- Stability when carrying
- Ease of use in the workplace
we incorporated feedback based on practical experience.
In OEM development,
the "perspective of the person actually using it" is indispensable.

That accumulation of trust
led to this OEM development.
