History of Kaizen

Since the definition of Kaizen is quite broad, there are several different

thoughts about the history of Kaizen. The most common version is that

it resulted from the competition between Nissan and Toyota.

The fact that Nissan won the Deming Price for quality in 1961 drove

Toyota even more aggressive in its approach to lean manufacturing.

Toyota therefore vowed that it, too, would win the Deming price. In

order to overcome certain quality issues Shigeo Shingo elaborated a

poke-yoke system. Based on the experience gathered during the

elaboration Tetsuichi Asaka and Kaomi Ishakawa developed the Toyota

Quality Circles in 1962. These Quality Circles were later called the first

real Kaizen event. In the same year Masaaki Imai founded the Kaizen

Institute, which promoted the Kaizen approach through the world.

Other theories about the origin of Kaizen are described in the paragraph

“Impact of cultural differences Japan, US, Europe” (Mika, 2000, p.5 )
