In a trial in which it was disputed whether driving a car in reverse at 16 km / h on a one-way road in Hyogo Prefecture and hitting a man and causing his death was a crime of dangerous driving manslaughter, the Kobe District Court admitted that the crime of dangerous driving manslaughter was established, saying, "It proceeded at this speed while driving in the opposite direction on a one-way road, and its meaning is completely different from moving forward." The 63-year-old defendant was sentenced to two years and six months in prison.

In April 2021, the defendant Kimion Sugimura (4), who was driving a passenger car, was charged with dangerous driving manslaughter for driving a passenger car in reverse for about 60 meters at a speed of 16 kilometers per hour on a one-way road in Amagasaki City, Hyogo Prefecture, and hitting and killing a 72-year-old man who was riding a bicycle.

The defense had sought to apply the charge of manslaughter by negligent driving, which carries a light penalty.

In his ruling on the 27th, Chief Judge Akira Maruta of the Kobe District Court said, "This speed does not make you feel the risk of causing an exceptional accident when moving forward, but if you are driving in reverse on a one-way road in reverse at this speed, the meaning is completely different from that of moving forward, and it is a speed that causes a serious traffic hazard."

On top of that, he sentenced him to 2 years and 6 months in prison, saying, "It should be said that it is an act that is out of common sense, and the high level of danger cannot be underestimated."
