TOKYO -- There appears to be no end in sight to the data falsification scandal at Kobe Steel, with the company admitting it could not guarantee more evidence of malpractice would not emerge.
"I sincerely apologize for creating distrust and concern among many people," Kobe Steel Chairman and President Hiroya Kawasaki told reporters on Thursday at the Ministry of Economy, Trade and Industry, where he met with Akihiro Tada, director-general of the Manufacturing Industries Bureau.
"The highest priority is to check the safety of products already shipped. We will use all necessary means to do so," Kawasaki said. The company plans to publish the results of its safety checks in about two weeks and compile an analysis of the causes of the incident, along with planned countermeasures, within a month, he said. "Trust in Kobe Steel has been reduced to zero," he added.
Kawasaki said that, as long as the scale of the scandal does not widen further, there would be "no impact" on company earnings; shipment has been halted on products accounting for 4% of overall sales.
Importantly, however, he said, "there is a possibility of more individual cases coming to light."
The economy ministry's Tada expressed his concern, saying that "the scandal has been seen by some as an incident that could undermine the trust in Japan's manufacturing industry as a whole."
The scandal has also spread beyond Japan, with General Motors and Ford Motor launching investigations into the possible effects on their products.
General Motors said on Wednesday that it is investigating aluminum and copper products supplied by Kobe Steel but provided no further information.
Kobe Steel has a long history of supplying aluminum products to automakers in the U.S. In 2016, it announced plans to build a new plant in the state of Kentucky to produce the material for the industry.
Aluminum is used to make the chassis lighter to increase fuel efficiency. Demand for the metal has been expanding in the U.S., with Ford using it in large volumes for its trucks.
In Japan, the aluminum products for which product quality data has been falsified, are used in cars and shinkansen bullet trains. Central Japan Railway said part of the chassis of its shinkansen trains has been discovered to lack the strength required by Japanese Industrial Standards. But the overall strength of the framework has been confirmed and there is no impact on safety, the company said.
Kyushu Railway said on Thursday that the products are used in 12 of its local trains. An inspection by a train maker has confirmed the safety of the carriages, and operations will continue as usual, the company said. Kyushu Railway also said it has not found evidence that the aluminum products are used in its shinkansen trains.
