Reiwa 6 (Wa) No. 831 Road Transport Vehicle Act Violation and Negligent Driving Causing Injury Case

In April 2025, in Tokyo, Japan, 28-year-old Hiroshi Sato operated a motor vehicle despite a suspended driver's license and without a valid mandatory vehicle inspection certificate. While driving through a residential area, Sato momentarily lost focus and failed to brake in time, colliding with pedestrian Yuki Tanaka on a crosswalk. Tanaka sustained severe leg fractures requiring extended hospitalization. Sato was arrested and charged with violations of the Road Transport Vehicle Act for the uninspected vehicle and with negligent driving causing injury under the Penal Code. The case was recorded as Reiwa 6 (wa) 831 at the Tokyo District Court. The prosecution highlighted the dual infractions, while the defense cited Sato's remorse and settlement with the victim.

The Tokyo District Court sentenced Hiroshi Sato to 18 months in prison, suspended for three years, and permanently revoked his driving privileges.

Whether the defendant's act of driving without a license and with an uninspected vehicle elevated the negligence to a degree warranting a harsher sentence, and whether dashcam evidence sufficiently proved momentary inattention.

The case intensified public calls for stricter penalties against unlicensed drivers and mandatory vehicle safety checks, and it was widely discussed on social media as an example of preventable traffic injuries.
