Kubota falsified inspection data on component used by steelmakers

OSAKA (Kyodo) -- Machinery maker Kubota Corp. said Wednesday it falsified inspection data on a component used in equipment to make steel plates, in the latest such conduct on quality control among Japanese manufacturers.

The Osaka-based company admitted to having inappropriately changed data such as the strength of the component in inspection reports submitted to client companies in order to meet specifications it had agreed on with customers.

Of 99 customers in and outside Japan, 85 have confirmed to have received the component with falsified inspection data from Kubota's plant in Hyogo Prefecture between October 2013 and July this year.

The component in question is called rolling mill rolls and used in machinery to turn solid metal blanks into steel plates.

Sales of the product totaled 4.4 billion yen ($40 million) in 2017, some 0.3 percent of the group's total sales.

"I offer a sincere apology for causing concern and inconvenience to all our customers and concerned parties," Kubota President Masatoshi Kimata said at a press conference.

Nissan Motor Co., Subaru Corp., Kobe Steel Ltd. and Mitsubishi Materials Corp. are also among companies recently found to have falsified product quality data.
