Company information
Tokai Parts Industry Co., Ltd. has been manufacturing and selling screw parts since its establishment in 1947, primarily producing bolts for transportation equipment manufacturers such as automotive and motorcycle companies. As the times have changed, customer needs have also increased, allowing us to manufacture a wide range of products from large "special bolts" to tiny "micro screws," and we have expanded our business to include not only transportation equipment manufacturers but also model kit manufacturers and IT-related companies. In recent years, we have also ventured into the medical field, developing implant products and surgical instruments for orthopedics, neurosurgery, and dentistry. Additionally, we have established an agricultural division that handles everything from the cultivation to the sale of fruits and vegetables. The foundation of Tokai Parts Industry is "the ability to think freely." We aspire to be loved by the public like the "karakuri puppets" that were popular in the Edo period, while pursuing our "dreams" with the craftsmanship and creative thinking that lies within.
