NO SIGN × Osu no Sushi｜Knife Case Development Case Study (Leather OEM)
OEM development of knife cases,
from Miyazaki to the world.
NO SIGN, in collaboration with the sushi school "Osu no Sushi,"
has developed a knife case using Miyazaki Wagyu leather.
This article introduces
the background and process of this OEM product development from scratch.
■ Background of Leather OEM Development
Osu no Sushi is a sushi school
based in Aoshima, Miyazaki Prefecture,
that promotes Japanese culture to foreigners.
Centered around sushi experiences,
they engage in activities that convey essential Japanese culture,
including pottery, sake, fermented foods, agriculture, and marine sports.
While providing "experiences that allow people to take Japanese culture home"
to people around the world,
the idea of "couldn't we productize the tools of a sushi chef themselves?"
led to the start of this leather OEM development.
■ Product Development Objectives
For a sushi chef, a knife is
not just a tool, but "skill itself."
・Safe to carry
・Durable enough for frequent travel
・Designed to embody Japanese aesthetics
A knife case that met these requirements,
combining practicality and brand identity, was needed.
■ Leather OEM Design (Development Points)
In this OEM development,
the design was based on the following key points:
・Use of Miyazaki Wagyu leather
・Structure to safely store multiple knives
・Design considering stability during transport
・Design with international appeal in mind
It was designed not just as a leather product,
but as a "product to be used in the field."
■ Reflecting Professional Perspectives
The development of this product also incorporated
the perspective of Mitsuhiro Tsumoto,
known for his "Ultimate Blood Removal" technique for fish freshness management.
After reviewing the samples,
・Knife fit
・Stability during transport
・Ease of use in the field
etc., feedback based on practical experience was incorporated.
In OEM development,
"the perspective of the actual user" is indispensable.

the shared vision of three entities
active globally from Miyazaki:
