Kozo Iizuka

Kozo Iizuka (飯塚 幸三, Iizuka Kōzō, IPA: [iizuka koː(d)zoː]; born 1931)[1] is a Japanese engineer who served as Director of the AIST[2] and President of the International Measurement Confederation [3] and Human Frontier Science Program[3] among other positions. On April 19, 2019, while driving his car, he killed a woman and her child, who were on a bicycle, and injured nine pedestrians in what is called the Higashi-Ikebukuro runaway car accident. Following the accident, perceived special treatment of him by the police, legal system and media, ostensibly due to his privileged position in society, drew much attention and criticism.

Life and careerEdit

Iizuka Kozo was born in Nakano in Tokyo in 1931.[4] He graduated from the University of Tokyo. He became a Doctor of Engineering in 1972.[5]

He was president of the National Institute of Advanced Industrial Science and Technology[6] and vice-president of Kubota corporation. While vice-president of Kubota, he also served as chairperson of a committee of the Science Council of Japan.[7]

In 2015, he was awarded the Order of the Sacred Treasure for Administrative Services in International Trade and Industry.[1]

Higashi-Ikebukuro runaway car accidentEdit

On April 19, 2019, while driving his Toyota Prius in the Ikebukuro district of Tokyo, Iizuka ran a red light and struck and killed a mother and daughter who were on a bicycle (Mana Matsunaga, 31, and her daughter Riko, 3), injured eight others at a pedestrian crossing, and his wife, who was riding with him. The reported cause of the accident was Iizuka stepping on the accelerator when he meant to apply the brake.[8][9] About a year before the incident, Iizuka had received treatment on his right knee and was advised by his doctor to drive as little as possible.[10]

In spite of Iizuka having caused a fatal accident, he was not arrested. Police stated that this was because Iizuka was injured at the scene and was elderly, and hence was not expected to run away or attempt to destroy evidence.[11] However, in similar accidents caused by elderly drivers that have occurred in Japan following Iizuka's, each and every suspect has been arrested almost immediately, regardless of their age and state of health. This has led to widespread scrutiny and criticism of the police in Japan in regard to just how impartially they enforce the law.[12]

One of the victim's parents started a campaign demanding that police prosecute Iizuka in line with normal practice and 390,000 signatures were collected. The petition was submitted to the National Police Agency of Japan.[13] Finally, on November 12, 2019, the Traffic Investigation Division of the Tokyo Metropolitan Police Department referred Iizuka to prosecutors on suspicion of causing fatal injury by negligent driving. Iizuka claimed that there was a mechanical problem with the brake and/or accelerator, but vehicle function tests revealed no mechanical defects. The Metropolitan Police Department concluded that negligent driving by Iizuka was the cause of the accident.[14] In February 2020, he was prosecuted.

Following the accident, Iizuka is reported to have explained that he was hurrying in his car to a French restaurant where he had made a lunch reservation, concerned that he and his wife would be late.[15]

Hearings began on 8 October 2020, in which Iizuka continued to deny the charges, claiming that the car had malfunctioned, and saying that he had no memory of accelerating the car.[16][17][18] On 4 March 2021, a 25 year veteran engineer from the car's manufacturer testified that they found no problems with the car's parts, but the defendant continued to profess that it was a malfunction.[19][20][21]

In interviews with the media, the husband and father of the woman and girl killed by Iizuka criticized Iizuka for not looking him in the eye when apologizing to him, and also questioned the sincerity of the apology, given how Iizuka continued to claim that he was not at fault.[22] The case drew an unusual amount of attention due to the apparent leniency Iizuka was treated with, and criticism that he was being treated as a notional "upper-class citizen" (Japanese: 上級国民, Hepburn: jōkyū kokumin), to whom regular rules do not apply. Many people pointed out that the Japanese police immediately arrest regular people, who are without such status or influence, but did not arrest Kozo Iizuka because of his social standing.[23]

In analyzing the reactions to the incident, Toyo Keizai commentator Atsushi Manabe writes that Iizuka's words and actions after the accident "added fuel to the fire", and as a result the case represents to people how unapologetic liars and coldblooded psychopaths succeed more than regular honest people, which goes against the zeitgeist of the common people. This "victory of brazen shamelessness" represents a loss of morals, and is why people feel disgust and anger.[24][25][26] Manabe also writes that, to many people, the case represents how Japanese law no longer functions as it should, with criminals being able to get away with their crimes by using their privileged position in society.[27]

The case renewed attention regarding the problem of accidents caused by elderly drivers[28][29] which was a pre-existing topic for several years before.[30] It was reported that in the aftermath of the accident, more elderly people voluntarily surrendered their driver licenses.[31]

A documentary covering the case will air on Tokyo Broadcasting System Television on 4 April 2021.[32]

Japanese Wikipedia article controversyEdit

Attention was also brought to Iizuka's article on the Japanese Wikipedia, which goes in-depth into his accomplishments, but has no mention of the incident. A small group of users constantly removed edits regarding the incident, before finally protecting the article so that nobody else could edit it. When brought up on the article's talk page, they cited this as being "the result of discussion by the community". Though the topic has been brought up multiple times since, with many topics on the talk page questioning the decision, all such attempts at discussion were answered with the same users saying that the topic was already discussed and decided upon by "the community". The problems with the Wikipedia article were widely discussed on social media, and subsequently reported on by multiple outlets in the Japanese news media, including major outlets such as Asahi Shimbun, which questioned the decision of the Wikipedia users.[33][34]

As of January 31st, 2021, the page remains protected with no mention of the incident.[35][34]

Also, about half a year after the incident, in November, he said in a television interview that he "wanted car manufacturers to apply to themselves to developing safe cars and thus create the kind of environment where the elderly can drive with a sense of assurance, and where they can go outside of their homes."

Behind these suspicions is a sense of crisis in regard to today's society not only possibly descending into a state of legal dysfunction where falsehood and injustice are openly tolerated, but where that is becoming increasingly embedded as the new normal. That is to say, an image has been formed of a society where the law isn't working properly, where criminals make use of their privileged position, and where they employ sophistry to clear themselves of wrongdoing. What is to become of things if, in real terms, this begins to come across as chaos, as the disarray of a society that lacks a legal structure?' Manabe, Atsushi (14 October 2020).
