A Japanese Paralympian is out of the Games after being hit by a self-driving vehicle inside the Athletes' Village.
The accident left judo competitor Kitazono Aramitsu, who has a visual impairment, with injuries to his head and legs.
Police say Kitazono was struck on Thursday afternoon while using a pedestrian crossing.
They say he was treated at a clinic inside the village and that his injuries will take two weeks to heal.
Kitazono was due to compete in the 81-kilogram class in the men's Para judo. He was forced to withdraw from a match scheduled for Saturday.
None of the seven people on board the electric shuttle bus were injured.
The Toyota vehicle is part of a fleet being used to transport athletes and Paralympic officials around the village.
Toyota Motor President Toyoda Akio posted an apology on the company's website.
He said self-driving vehicles have struggled to cope with the special environment of the Paralympics, which includes people who can't see and those with other impairments.
