Remember that Japanese industry was damaged extensively during WW II. After the war was over the US government gave assistance to the Japanese and the goods that were imported by the US helped to restart the Japanese economy. A lot of these items were of low quality and price, but from the perspective of the Japanese manufacturers, that was what Americans wanted to buy. When the terms "Made in Japan" and "cheep" became synonyms, Japanese companies steadily worked to raise the quality of their products. The JCII program was a further effort to combat against the impression that Japanese products were inferior.
