Reiwa 7 (U) No. 233 Dangerous Driving Causing Death or Injury and Road Traffic Act Violation

On April 12, 2025, in Utsunomiya, Japan, Kenji Tanaka, 26, drove intoxicated at over 100 km/h in a 40 km/h zone, ran a red light, and struck pedestrian Yuki Nakamura, killing her instantly, while two others sustained injuries. He was arrested at the scene and charged with dangerous driving causing death or injury under Article 208-2 of the Penal Code and multiple Road Traffic Act violations, including driving under the influence. The prosecution argued that his severe intoxication and excessive speeding constituted a willful disregard for safety. The defense contended the crime should be classified as negligent driving causing death, not dangerous driving, which carries a lighter penalty. Security camera footage capturing the incident intensified public scrutiny.

The Utsunomiya District Court convicted Tanaka of dangerous driving causing death or injury and Road Traffic Act violations, sentencing him to 10 years of imprisonment with hard labor. The court emphasized that his very high blood alcohol content, deliberate excessive speeding, and blatant disregard for traffic signals met the criteria for willful endangerment and showed a grave deviation from ordinary driving care.

The core dispute was whether Tanaka's actions satisfied the legal threshold for "dangerous driving causing death or injury," which requires driving under the influence of alcohol to the point of being incapable of normal operation or driving at substantially excessive speeds with gross negligence. The defense argued that while Tanaka was reckless, his condition did not completely impair his driving ability and thus the crime should be downgraded to negligent driving causing death or injury, carrying a significantly shorter maximum sentence.

The case reignited public anger over lenient sentences for drunk and reckless driving in Japan. Victim advocacy groups cited the case to push for legislative reforms, including mandatory minimum sentences and mandatory installation of alcohol interlock devices for repeat offenders. The incident prompted intensified police crackdowns on drunk driving in the Tochigi area and nationwide educational campaigns highlighting the severe consequences of dangerous driving, while lawmakers faced renewed pressure to amend the Penal Code for stricter penalties.
