Nippon Telegraph & Telephone’s data subsidiary is joining forces with Toyota Motor to develop connected cars that can collect and share data.

NTT Data will actively consider mergers and acquisitions to accelerate a push into overseas markets, Yo Honma, the networking and data subsidiary’s chief executive officer, said in an interview. Honma sees the company spending as much as ¥400 billion ($3 billion) for deals over the next four years.

Toyota and other Japanese carmakers have been ramping up efforts to develop electric vehicles and connected cars, which can communicate with each other and outside networks to improve autonomous driving, performance and in-car features. New connected-car sales are on track to reach 94.8 million units globally in 2035, almost tripling from 2020, according to researcher Fuji Keizai Group.
