The Japanese government urged steelmaker Kobe Steel to clarify the extent of manipulation of inspection data on steel, aluminum and other metals used in a wide range of products, reportedly including rockets, aircraft and cars, in the latest quality scandal to rock Japanese manufacturing.

Kobe Steel, Japan’s third-largest steel maker, has announced that between Sept. 1, 2016 and Aug. 31 of this year it sold aluminum and copper materials using falsified data on such things as the products’ strength.
