Our History

We are a furniture parts manufacturer that was founded in Tokyo back in 1945. Initially, we began as a small family business with a small office. For more than 70 years we have supplied high quality and highly functional products. Having earned the trust of customers, today, we maintain business relationships with more than 1,000 companies, including major international furniture manufacturers such as Okamura Corporation and Kokuyo Co.,Ltd. not to mention medical equipment manufacturers and metal trading companies.
In 1960, we created the product brand PLA-PART and later registered it as a trademark.
This brand name is given to the highly functional parts we develop. After a half a century in the business, the name PLA-PART has now become widely known not only as our product line, but as a general term in Japan associated with high end, highly functional parts for chair and desk legs.
PLA-PART is now an established brand and a source of pride.
