Several Japanese automakers including Toyota Motor Corp. reported damage to cars and facilities after two huge explosions at the Chinese port of Tianjin tore through an industrial area where toxic chemicals and gas were stored.

The blasts in the city of Tianjin on Wednesday night killed at least 50 people, including a dozen fire fighters, state media said. About 700 people were injured.

Toyota said on Friday the blasts broke windows at its car assembly, logistics, and research and development facilities, which are jointly run with China FAW Group Corp. Operations had been closed for a weeklong summer holiday and no one was injured, it said.
