More corporate misconduct by yet another major Japanese firm emerged Tuesday as Toray Industries Inc. said its group falsified quality test data.

Toray Hybrid Cord Inc., an Aichi-based subsidiary of Toray and maker of tire and other industrial reinforcement cords, said it identified 149 cases out of 40,000 in which two employees in charge of quality assurance modified figures.

In these cases, which occurred between 2008 and 2016, the strength of the materials did not meet the standards promised to customers.
