Japanese Reporter Hits Dummy in Drink Driving Test After Saying She Felt Confident

A missed brake turns an Okinawa safety lesson into a viral warning

A rookie television reporter drank four cans of beer and four glasses of wine in about an hour, told viewers she still felt confident about driving, then struck a dummy on a closed driving course in Okinawa.

The reporter, Nakamura of Ryukyu Asahi Broadcasting, known as QAB, was taking part in a supervised exercise in Tomigusuku City on September 18. Her breath alcohol reading before driving was 0.5 milligrams per litre, about 3.3 times Japan's 0.15 mg/L threshold for driving with alcohol above the legal limit.

An instructor was sitting beside her and told her to brake. She reacted too late. Afterward, Nakamura said she had become confused about left and right, despite believing before the test that she could handle the car.

The footage reached a large audience after appearing on QAB's evening news programme CATCHY and its YouTube channel on October 15. A clip circulating on X attracted more than 45 million views, while the YouTube video passed 1.82 million views.

Behind the viral moment was a persistent local problem. Okinawa had recorded Japan's highest proportion of crashes involving alcohol among traffic accidents causing injury or death for five consecutive years. The exercise put a concrete example beside that statistic: a driver who felt only mildly affected could still miss an instruction and hit something directly in her path.

What happened at the September 18 exercise?

Tomigusuku Police Station and Orion Beer organised the September session, which brought together about 20 people, including representatives of drinks manufacturers and the media. Participants drank before moving to a driving school for supervised tests.

Beer, wine and awamori, an Okinawan distilled spirit, were among the drinks served during the drinking period. Nakamura said she consumed four cans of beer and four glasses of wine in roughly one hour.

The driving course included reversing manoeuvres, tight turns and an obstacle exercise involving a dummy. An instructor accompanied Nakamura in the car as a safety measure. The test took place on a closed course, away from ordinary road traffic.

Nakamura, the QAB reporter taking part in the demonstration, described her condition before getting into the vehicle:

I feel tipsy, but I am confident in my driving.

She initially completed tight turns by taking her time. The failure came during the obstacle exercise, when she needed to respond to the dummy and the instructor's braking instruction. Her response was too slow, and the car struck the dummy.

Confidence lasted longer than control

Nakamura's account after the drive was very different from her assessment before it. She said she had considered herself a confident driver, yet had hit the dummy despite being warned to brake.

The reporter described her confusion after completing the exercise:

I could no longer tell right from left. I thought drunk driving was very frightening.

Driving requires several tasks to happen together: watching the road, understanding a hazard, choosing a response and moving the hands or feet in time. Alcohol can interfere with judgment, coordination and reaction time. A driver may still feel capable while struggling to complete that chain of actions.

The instructor's presence made the failed response particularly striking. Nakamura received a direct instruction to brake, yet did not stop in time. On a public road, pedestrians and other drivers may appear without any warning from someone sitting beside the driver.

Other participants also made mistakes during the session, including mounting a kerb. Some had expressed confidence beforehand; others were already worried about driving after drinking. Their experiences showed how difficult it could be to judge their own performance while affected by alcohol.

What does a reading of 0.5 mg/L mean?

Nakamura's breath test measured alcohol in the air she breathed out. A result of 0.5 mg/L means the test detected 0.5 milligrams of alcohol per litre of breath. It is a different measurement from the blood alcohol percentages commonly used in some other countries.

Japan's threshold for the offence of driving with alcohol above the prescribed limit is 0.15 mg/L of breath. Dividing Nakamura's reading of 0.5 by 0.15 gives approximately 3.3, explaining the comparison used during the demonstration.

The exercise used 0.5 mg/L as its drinking target. The broadcast also referred to a Road Traffic Act amendment taking effect on July 21, 2026, and described that figure as a threshold for the more serious category of drunk driving. Fukuoka Prefectural Police identifies the year as Reiwa 8 (2026) and explains the new numerical criterion: "A breath alcohol concentration of 0.5 mg/L or higher also qualifies as 'drunk driving'." The category is known in Japanese as 酒酔い運転. The practical warning for drivers starts at the lower figure: 0.15 mg/L already reaches Japan's prescribed breath alcohol limit.

The amount Nakamura drank cannot be converted into an exact alcohol dose from the details given. The sizes of the beer cans and wine servings, and their alcohol strengths, were not specified. Body size, the speed of drinking and other personal factors also affect the reading.

For someone deciding how to get home, counting drinks is an unreliable way to assess driving ability. Nakamura's own description of feeling tipsy sat alongside a measured reading well above the prescribed limit and a failed braking response.

Okinawa's figures explain why the test was held

Okinawa's position at the top of the national ranking concerned the share of traffic accidents causing injury or death that involved drinking. The prefecture had held that position for five consecutive years.

Earlier official figures appear in the Traffic White Paper Digest, published by the Okinawa Prefectural Police Traffic Department in June 2023. For 2022, it recorded alcohol involvement in 2.05% of Okinawa's crashes, about 2.5 times the national average of 0.82%, placing the prefecture worst nationally for the second consecutive year. Alcohol-related crashes accounted for 9.4% of fatal crashes, about 1.6 times the national average of 5.8%, placing Okinawa sixth worst nationally.

That measure describes how prominent alcohol was within Okinawa's injury crashes. A relatively high share means drinking was involved in a larger portion of those crashes than elsewhere in Japan. The ranking concerns a proportion, rather than the total number of accidents.

The Japan Insurance Association's prefectural drink driving table, updated on September 7, 2026, uses 2025 data from the Institute for Traffic Accident Research and Data Analysis (ITARDA), with the figures calculated by the association. Its scope is crashes involving a motor vehicle or moped as the first party, including alcohol-related categories covering intoxication, alcohol above or below the prescribed limit and undetectable readings. The accident rate is the share of all such first-party crashes involving alcohol. Rates and crash counts per 100,000 licence holders are rounded, so rankings may differ even where displayed values match.

Police enforcement figures presented alongside the exercise recorded 1,097 people apprehended for drink driving in the preceding year. By the end of August in the year of the demonstration, authorities had recorded another 606 drink driving cases.

Accidents had occurred in 190 of those 606 cases. That is about 31%, or roughly three in every ten recorded cases. The figures show how often enforcement involved an accident as well as a driver who had been drinking.

The two enforcement totals cover different periods, one a full preceding year and the other only through August. For Okinawa residents, the immediate concern is concrete: police were continuing to encounter hundreds of drink driving cases, with accidents involved in a substantial portion of them.

For a separate, earlier period, the Okinawa Prefectural Police digest's published traffic-enforcement table recorded 1,025 drink driving citations in 2022, down by 164, or 13.8%, from 1,189 in 2021. The three serious traffic violations covered by the digest, drink driving, driving without a licence and exceeding the maximum speed limit, generated 2,511 citations in 2022.

How the footage spread beyond the driving course

QAB introduced Nakamura as a new reporter on CATCHY in April. Her September driving exercise reached television viewers the following month, then spread widely through social media.

The main dates show how a local road safety event became a much larger online story:

• April: Nakamura was introduced as a new reporter on CATCHY.
• September 18: She joined the drink driving exercise in Tomigusuku City.
• October 15: The report aired on CATCHY and was uploaded to QAB's YouTube channel.
• Within five days of publication: The YouTube video passed one million views.
• October 22: QAB promoted the video again through its official X account.

The YouTube audience subsequently grew beyond 1.82 million views, while the widely shared X footage exceeded 45 million views. Some online comments focused on how much Nakamura had drunk and her claim to feel only tipsy.

The collision gave the video its most serious moment. Viewers could see the gap between the reporter's confidence before driving and her difficulty responding once the car was moving. QAB's October 22 promotion brought renewed attention to the danger the exercise was intended to demonstrate.

The warning extends to people around the driver

The head of Tomigusuku Police Station's traffic division urged people around a drinker to intervene, rather than leaving the decision entirely to the person who had consumed alcohol. The police message was to prevent drink driving, stop others from doing it and refuse to tolerate it.

Nakamura's experience helps explain that approach. Before the drive, she felt capable. After it, she described confusion and fear. A person whose judgment has been affected by alcohol may be poorly placed to decide whether they can safely operate a vehicle.

For friends, colleagues and family members, the practical response is to arrange another way home or prevent someone who has been drinking from taking the wheel. Decisions about transport are easier to make before drinking begins than after a person has become convinced they are still fit to drive.

The Tomigusuku exercise ended with a dummy being struck on a controlled course. Its relevance to Okinawa's roads lies in the same sequence occurring without that protection: a driver feels confident, a hazard appears, and the response comes too late.
