Police on Tuesday referred to prosecutors the case of an 88-year-old former senior bureaucrat who was involved in a Tokyo car crash that left a toddler and her mother dead and prompted many elderly Japanese to surrender their driver’s licenses for fear of causing a similar accident.
The police concluded after a seven-month investigation that the April accident was caused by Kozo Iizuka, former head of the Agency of Industrial Science and Technology, rather than a problem with his car.
The police did not disclose whether Iizuka admitted to the charge of negligence resulting in death. He has said he may have mistaken the gas pedal for the brake, according to investigative sources.
The April 19 accident killed Mana Matsunaga, 31, and her daughter, Riko, 3, while leaving eight people injured, including Iizuka’s wife, who was a passenger in the car.
The police handling of the case, in which Iizuka was not arrested, has attracted criticism, with speculation that he received favorable treatment due to his social standing.
The police cited the improbability of Iizuka fleeing or destroying evidence when explaining their decision not to arrest him. He voluntarily answered police questions after he was discharged from hospital.
Iizuka’s car started to accelerate 200 meters away from the crash site in the Ikebukuro district and changed lanes several times to pass other cars, the police said. The car was traveling at nearly 100 kilometers per hour when entering the crosswalk where the mother and daughter were hit.
The police also suspect Iizuka may have been suffering the effects of Parkinson’s disease, which causes hand and leg rigidity, among other symptoms, at the time of the incident, the sources said. His doctor had not permitted him to drive a car.
The prosecutors will continue to investigate the case before deciding whether to indict him.
In September, the husband and father of the deceased submitted to prosecutors a petition signed by about 390,000 people calling for a harsh punishment to be handed down to Iizuka.
“I believe having (the driver) face the punishment he deserves will lead to the prevention of similar accidents,” the man said in August. He declined to be named.
An increase in traffic accidents caused by elderly drivers has become a major social problem as the population rapidly grays.
While police regularly urge elderly people to surrender their driver’s licenses, many older residents resist, citing a lack of public transport options and the need to drive for daily necessities, particularly in rural areas.
Some 37,000 people gave up their licenses in the six-month period after the accident, nearly double the number for the same period a year before, according to police.
In 2019, around 53,700 people had surrendered their licenses as of the end of October, already topping the previous annual record, they said. Around 80 percent of them were age 70 or older.
The involvement of driver error in fatal accidents increases in line with the age of the drivers.
Just 0.5 percent of fatal accidents involving driver error between 2015 and 2017 were caused by people under 70 years old, compared with 5.1 percent for people age between 75 and 79, and 7.6 percent for people age 80 or older, the police said.
The government is considering introducing tighter rules for elderly drivers, including only allowing them to drive cars equipped with a system to prevent sudden acceleration.
