Promote work style reforms with scientifically based Support Gear

Many people who are involved in work such as
in industry, agriculture, medical care and welfare have
a lot of physical burden and complain physical pain.

We would like to energize the working people
by providing our Support Gears that are highly effective
in reducing the work load.

We utilize the know-how cultivated in the support technology of medical products
and we assist you to work more actively.


Daiya, with more than 50 years of sewing experience has developed and manufactured braces and supports. We are particular about “Made in Japan” and manufacture high quality products. There are as many health needs as there are people. We are refining our manufacturing spirit and technology, hoping to meet all of these requirements.


We do not compromise on the structural design of the product so that users say that it is "really useful".
We take the idea into shape, make prototypes until we are satisfied, and send only those backed by objective evidence data to the world as finished products.

Ease of use

We would like to be close to people's pain and support workers. We collect needs related to labor reduction based on the voices of the field and develop products. And even after the prototype, we will conduct a monitor survey on site to pursue ease of use. We develop wearable, easy-to-move products that are close to the workers.
