Kawasaki broke ground on Irvine headquarters.

The company, the U.S. distributor of Kawasaki motorcycles, all-terrain vehicles and Jet Ski watercraft, began construction Thursday on a $10-million, 220,000-square-foot corporate headquarters on 22 acres in Irvine Spectrum, a planned business community near the San Diego and Santa Ana freeways. With its estimated 400 employees, the U.S. subsidiary of Kawasaki Heavy Industries Ltd. of Hyogoken, Japan, is now headquartered in Santa Ana. Among operations consolidated into the new facility are administration, sales, marketing, data processing and research and development. Construction is expected to be completed by March.
