Message from the President

Hirofumi Imamura

In January 2015, our company started a new path as a specialized manufacturer of bead wires for tires, wholly owned by Yokohama Rubber Co.
Our company is located in a corner of Meihan Kameyama-Seki Plant Complex in Kameyama City, known for Kameyama-juku and Seki-juku on the Tokaido-way.

We manufacture and sell bead wires, the main parts of tires, to Yokohama Rubber's tire production bases in Japan.
We hope to support Yokohama Tire by manufacturing safe, high-quality, and high-performance products using the advanced technology we have cultivated since our establishment.

With "Challenge, Fair, Open" as our action guideline, we are working every day to become a company where employees themselves act as parts manufacturers that maintain the quality of Yokohama Tire and continue to take on new challenges as one.

Health and safety activities

Safety and health committee meetings and safety patrols are held once a month to check for hazardous areas in the plant.
In addition, we strive to identify and eliminate risks that may lurk in daily operations by attending KYT classes outside the company, conducting risk assessment activities, and submitting near-miss reports, thereby creating a safe working environment.

Disaster Response

We focus on disaster drills such as in-house evacuation drills (once a year) and safety confirmation drills using an app (four times a year).
We also participate in disaster drills in cooperation with Yokohama Rubber to identify problems and make improvements.
