As the IT revolution injects extra octane into the auto industry with driverless technology, DeNA Co. said Thursday it will steer toward an innovative new target: robot taxis.

Best known for its Mobage cellphone video game platform, DeNA said it will team up with ZMP Inc., a developer of automated driving technologies, and set up a joint venture called Robot Taxi on Friday.

"The auto industry is so huge . . . about ¥50 trillion in all, the biggest industry in Japan. This is very attractive to DeNA," said DeNA executive Hiroshi Nakajima at a news conference in Tokyo. Both DeNA and ZMP are based in the capital.
