神戸製鋼所
In October 2017, Kobe Steel admitted to falsifying data on the strength and durability of its aluminum, copper and steel products. The scandal deepened when the company said it found falsified data on its iron ore powder, which caused its shares to fall 18%. By 11 October, shares had fallen by a third. After testing the parts of their bullet trains, the Central Japan Railway Company announced that 310 components were discovered to contain sub-standard parts supplied by Kobe Steel.
