Established in 1872, our predecessor, Byosada Shoten began operations in Kanda, Tokyo.
Since our founding, we have specialized in the manufacturing and sales of fastening parts, earning a solid reputation as a trusted and long-established presence in the industry.
In today’s dynamic business environment, adaptation is essential. In collaboration with our partners, we have built a production and quality control system that ensures a prompt and precise response to our clients’ needs.
Though often unnoticed, screws and fasteners are essential elements that support the very foundations of society—from machinery to infrastructure.
While circumstances may change, our mission remains unchanged: to listen to our clients and respond with integrity and innovation. This commitment will guide us toward our 160th anniversary and beyond.
We welcome individuals who share this vision and are ready to contribute to a company built on trust and lasting value.
