Masaaki Imai is a Japanese management consultant, known for his work on quality management, specifically on Kaizen.

In the late 1950’s, Imai worked for five years in Washington DC at the Japanese Productivity Center, where he was responsible to accompany groups of Japanese businessmen on visits to American plants.

In 1986, he founded the Kaizen Institute Consulting Group (KICG) to help western companies to introduce the concepts, systems and tools of Kaizen.

His first book, Kaizen: The Key to Japan’s Competitive Success, helped popularize the Kaizen concept in the West.
