Japan-based Diamond Electric is relocating its North American headquarters to Eleanor, West Virginia. The move will consolidate the automotive ignition coil manufacturer’s main U.S. office with its existing operation in Putnam County.

“This change will streamline Diamond Electric’s United States operations by improving accessibility between departments and it will strengthen our internal and external communications,” said Hironori Kurita, Chairman of the Board for the Japanese-owned U.S. company. “We will continue to maintain a sales office in southeast Michigan to provide quality service to our valued customers.”

Diamond Electric supplies ignition coils to Ford Motor, Chrysler, Toyota and Subaru. The company currently employs approximately 335 workers in West Virginia. The employees in Michigan are being given an opportunity to relocate with the company to West Virginia, which is expected to add 10 to 15 positions to the Eleanor site.

“Since Diamond Electric opened its first manufacturing plant in West Virginia in 1997, the company has chosen to expand its operations in the Mountain State multiple times,” Governor Earl Ray Tomblin said. “We’re honored Diamond Electric has selected West Virginia as the new home for its headquarters facility. I truly appreciate the confidence in not only our state and our business climate, but West Virginia’s growing and dependable workforce as well.

Over the years, the operation in Eleanor has grown into the company’s largest production facility in the world, the Governor’s Office said. In addition to the United States and Japan, Diamond has operations in five other countries across the globe.
