Hikari Seiko is the top manufacturer of universal joints, the parts that transfers engine power to the rear wheels through the transmission or conveys the steering wheel movement to the front wheels.

In its factory you will find that much of the specialized equipment, such as the rows of machining equipment, has been developed by Hikari Seiko itself. It has developed assembly machines that can accurately and efficiently perform such tasks as installing needle rollers without spacing to the inner surface of the metal cap of a cylinder, as well as building a grinding machine capable of working on four areas simultaneously.

Moreover, by carrying out operations such as cold forging, heat processing, machining, assembly and evaluation testing in house, it can create products that guarantee performance quickly and at a low cost. This exemplifies the spirit of Japan's monozukuri, as it puts into practice the aims of high precision, high quality and low cost.

The uniqueness of Hikari Seiko can also be seen in its management style. Every morning, the President arrives at the company at 7:20 a.m. and reviews the events of the previous day as reported by his top management. At 8:00, the President then makes an assessment of the work area himself. Since the morning is reserved for improvement programs by the improvement teams, no contact is made with other businesses. Hikari Seiko has also dedicated itself to enhancing the satisfaction of its employees, so there is an emphasis on improving the employee dining area and providing restrooms on a par with top hotels. The company President, Mr. Nishimura, is also the executive secretary of the Mie High-tech Forum, a group that promotes interaction among different types of businesses. He is also actively developing ties with those in the academic field of manufacturing engineering. The culmination of these activities contributes greatly to the improvement of the company's technology and skill as well as to the betterment of its employees.

Hikari Seiko is making plans to build a new factory to further strengthen its involvement with CVJ (Constant Velocity Joints) that are so widely used in front-wheel drive vehicles. It also has plans to expand its business into the mass production of fuel adjustment valves, parts that demand micron-level precision.

Through its blend of high-precision machining technology and unique business strategy, Hikari Seiko is ready to lend its support to the automotive industry of tomorrow.
