Japanese telecom giant SoftBank Group has invested in two U.S. companies, a map software startup and an artificial intelligence startup, the two American companies said on Tuesday.

Mapbox, based in San Francisco, said it has received an investment worth $164 million from a group of investors, including SoftBank Vision Fund, set up jointly with the government of Saudi Arabia among others, and several venture capitals. The investment will be used in three areas: autonomous driving, augmented reality, and virtual reality technologies for games and expansion into China, Southeast Asia and Europe.
