Nissan Motor Co. and mobile game-maker DeNA Co. said Friday that they will launch an autonomous-driving taxi service for a two-week experiment in Yokohama next month, with the participation of 300 groups of people who will be asked to give feedback after using the ride-hailing app.

The companies aim to officially launch a full service in the early 2020s.

The world has yet to see a hailing service for a self-driving taxi, so ¡°we are going to learn about some of the things that maybe we can¡¯t foresee without actual testing,¡± said Ogi Redzic, senior vice president of the existing alliance among Nissan, Renault SA of France and Mitsubishi Motors Corp., during a news conference in Yokohama.
