Go-karts have become a common sight on Japan's busy streets, but safety concerns were raised Thursday when police data showed that 50 accidents had occurred in Tokyo over a recent 11-month period.

Foreign drivers were involved in 86 percent of the crashes, which took place between March 27 of last year and Feb. 26, according to National Police Agency data released Thursday. Out of the 50 accidents, 43 involved foreign drivers.

On Feb. 23, a 35-year-old Taiwanese man driving a go-kart was arrested on suspicion of negligence resulting in injury after hitting an 18-year-old male cyclist and driving away.
