Toyota Motor will shut down all plants in Japan on the 1st due to a system failure at a major customer parts manufacturer.
The company considers that it may have been hit by a cyber attack and is investigating the cause, and is rushing to restore the system with the aim of resuming operations as soon as possible.
Toyota Motor Co., Ltd. had a system failure last night at one of its major customers, the parts manufacturer Kojima Press Industry Co., Ltd. in Toyota City, Aichi Prefecture. Announced that it will stop operating for one day.
All factories that manufacture Toyota cars will be shut down.
According to the parts manufacturer, on the night of February 26, it detected a signal that one of the servers went down and took steps to turn off all the servers in the company for safety.
As a result, it became impossible to exchange data such as the number and timing of parts to be delivered with Toyota.
It seems that Toyota has decided to suspend the operation of all plants because it may hinder future production because parts of this manufacturer are used in many car models.
According to the company, it will not be possible to produce about 13,000 units a day.
