Japanese carmakers, including Toyota Motor Corp., have ordered their employees based in Russia to return home to secure their safety amid the Ukraine crisis, they said Monday.

Toyota is evacuating around 30 employees and their 20 family members. Nissan Motor Co., Subaru Corp. and Mitsubishi Motors Corp. have also made similar arrangements.

Toyota said its decision is "based on the advice of the Japanese government and the situation of local businesses."

Toyota suspended operations at its plant in St. Petersburg last Friday due to supply chain disruptions. Meanwhile, Nissan said Monday it will temporarily halt production at its factory in the Russian city soon.

A total of 347 Japanese companies were operating in Russia as of February, according to credit research company Teikoku Databank Ltd.

Among them, 45 percent were carmakers and other manufacturers. Wholesalers, including trading houses, accounted for 25 percent while services and financial sectors made up 10 percent each, it said.

Telecom company KDDI Corp. also said it plans to evacuate employees from Russia.
