Toyota Motor Corp. will cut summer bonuses for some 9,800 managers by 4 to 5 percent, as it looks to tighten cost control in the face of high spending on developing technology for autonomous and electrified vehicles, a source close to the matter said Thursday.

The decision comes even as the company expects a 19.5 percent rise in net profit in the current fiscal year, and reflects an uncertain business outlook due to the prolonged trade war between the United States and China, the source said. Toyota President Akio Toyoda said Thursday at an annual shareholders' meeting that his company is boosting efforts in developing zero-emission vehicles including fuel cell vehicles. "We are facing a once-in-a-century transformation. I hope to build a mobility society of the future with our shareholders," Toyoda said at the meeting at its headquarters in Aichi Prefecture.

Competition is intensifying, with new rivals such as technology giant Google LLC now in the markets for electric and self-driving vehicles and new transportation services.
