Case of Negligent Driving Causing Death (Reiwa 7 (Wa) No. 108)

On April 12, 2025, in Tokyo, defendant Kenji Tanaka, a 72-year-old driver, struck and killed 58-year-old pedestrian Hanako Suzuki while making a left turn without properly checking the crosswalk. Tanaka was arrested and charged with negligent driving resulting in death under the Criminal Code. During the trial at the Tokyo District Court (case Reiwa 7 (Wa) No. 108), the prosecution argued that Tanaka failed to fulfill his duty of care, while the defense claimed the victim suddenly ran into the street. The victim's husband, Taro Suzuki, participated as a civil plaintiff. The case centered on whether the driver's actions constituted gross negligence.

On October 20, 2025, the Tokyo District Court found Tanaka guilty, sentencing him to 2 years in prison suspended for 3 years, emphasizing his remorse and compensation payment.

The core dispute was whether the defendant's failure to observe the pedestrian constituted criminal negligence and whether a suspended sentence would be appropriate given the victim's family's demand for a custodial sentence.

The case intensified public debate on elderly driver accountability and prompted calls for mandatory cognitive tests for license renewal, leading to a national review of traffic safety policies.
