Significant progress was put in reducing the numbers of car accidents in Japan over the past decade, but recent data shows a concerning reversal. Between 2013 and 2022, the country consistently saw a decline in both accidents and fatalities, reaching a record low of 2,610 deaths in 2022. However, in 2023, traffic-related fatalities rose for the first time in eight years, totaling 2,678 deaths. This uptick suggests new challenges in road safety, including an aging driver population and increased distractions from mobile devices.
The total number of car accidents in Japan also followed a downward trend, decreasing from over 600,000 incidents in 2013 to approximately 307,911 in 2023. This drop is largely due to stricter traffic laws, improved vehicle safety features, and national awareness campaigns. However, the 7,072 increase in accidents from 2022 to 2023 indicates that Japan may need to reinforce road safety initiatives to prevent further setbacks.
Fatalities and Injuries Breakdown
In 2023, Japan recorded 2,678 traffic-related deaths, a slight but significant increase from the previous year. Injuries also rose to 365,027 cases, reflecting a 8,426 increase compared to 2022.
One of the most alarming trends is the high fatality rate among elderly individuals. In 2023, 54.7% of all traffic deaths involved people aged 65 and older, highlighting the growing safety concerns for senior drivers and pedestrians. This demographic remains the most vulnerable, often involved in collisions due to slower reaction times and misjudgment in traffic situations.
Pedestrians and cyclists are also among the most affected. Nearly 40% of all fatalities in 2023 were non-motorists, with many incidents occurring at intersections and crosswalks. The rise in pedestrian deaths emphasizes the need for enhanced road safety measures, particularly in urban areas where foot traffic is high.
Regional Differences in Car Accidents in Japan
Traffic accident trends vary widely across Japan, with some prefectures consistently reporting higher fatality rates than others. In 2023, Osaka recorded the highest number of traffic deaths (148), followed by Aichi (145) and Tokyo (136). These urban centers have dense road networks and heavy traffic congestion, increasing the likelihood of serious accidents.
On the other end of the spectrum, Saga Prefecture reported the lowest fatalities, with only 13 deaths. Additionally, when comparing accident rates per 100,000 people, Tokushima (3.98), Mie (3.79), and Aomori (3.74) had the highest fatality averages, while Tokyo had the lowest rate (0.977). This suggests that while Tokyo experiences a high volume of accidents, its safety infrastructure and strict enforcement contribute to lower per-capita fatalities.
The disparity in accident rates across regions highlights the importance of location-specific safety strategies. While urban areas struggle with traffic congestion and pedestrian-related car accidents in Japan, rural regions face challenges like bad road conditions, lower visibility, and higher speeds. Checking these risks is crucial for reducing traffic fatalities across Japan.

Why Are Car Accidents in Japan Increasing?
One of the leading causes of the recent rise in car accidents in Japan is distracted driving, particularly due to smartphone use. Despite strict laws prohibiting the use of mobile phones while driving, many drivers continue to engage in activities such as texting, checking navigation apps, or even browsing social media. The penalty for using a smartphone while driving was significantly increased in 2019, yet enforcement remains a challenge.
According to police reports, more than 20% of car accidents in Japan in urban areas are linked to driver distraction, with smartphone use being a primary factor. Even momentary inattention, such as looking at a notification, can lead to rear-end collisions, lane deviations, or failure to notice pedestrians at crosswalks. To combat this issue, Japan has increased awareness campaigns and encourages the use of hands-free technology and in-car AI assistants.
Elderly Drivers and Road Safety Challenges
Japan has one of the world’s oldest populations, and this demographic shift has had a noticeable impact on road safety. In 2023, over 54.7% of traffic fatalities involved drivers or pedestrians aged 65 and older, underscoring the risks associated with aging drivers. Slower reaction times, decreased vision, and cognitive decline contribute to misjudging distances, pressing the wrong pedal, or failing to stop at intersections.
Weather and Road Conditions
Japan’s diverse climate and seasonal weather conditions also contribute to car accidents. Heavy snowfall in northern regions, such as Hokkaido and Tohoku, leads to slippery roads, reduced visibility, and an increased risk of skidding. In winter, car accidents in Japan due to black ice and snow buildup are among the highest causes of fatalities.
Meanwhile, typhoons and heavy rainfall during Japan’s rainy season (June–July) result in hydroplaning and road surface damage, leading to poor braking efficiency and higher collision risks. Additionally, foggy conditions in mountainous areas reduce visibility, making driving hazardous.
Urban vs. Rural Accident Rates
Traffic accident trends vary significantly between urban and rural areas in Japan. Cities like Tokyo, Osaka, and Nagoya have higher accident frequencies due to dense traffic, complex intersections, and a high number of pedestrians and cyclists. However, these urban areas generally have lower fatality rates due to strict traffic enforcement, speed limits, and advanced road safety infrastructure such as pedestrian overpasses and automated traffic control systems.
In contrast, rural prefectures such as Aomori, Mie, and Tokushima report higher fatality rates per capita. This is due to factors like:
- Higher speed limits and less traffic congestion, leading to more severe collisions.
- Fewer streetlights and road safety measures, increasing the risk of night-time accidents.
- Longer emergency response times, as rural areas have fewer medical facilities nearby.
What Are the Most Common Causes of Car Accidents in Japan?
Speeding remains a significant factor in many car accidents Japan, particularly on expressways and rural roads where drivers may feel less restricted. While Japan has strict speed limits typically 100 km/h on expressways and 40–60 km/h on city roads, many drivers exceed these limits, especially late at night or in areas with low traffic enforcement.
Reckless driving behaviors, such as tailgating, aggressive lane changes, and sudden braking, also contribute to severe car accidents in Japan. Police reports indicate that excessive speed is a leading factor in fatal crashes, as it reduces reaction time and increases impact severity. Recently, Japan has implemented automated speed enforcement cameras, and penalties for dangerous driving have been strengthened under the 2020 Road Traffic Law amendments.
Drunk Driving Laws and Enforcement
Japan has one of the strictest zero-tolerance policies on drunk driving in the world. Even a blood alcohol concentration (BAC) as low as 0.03% (well below the U.S. and European standards) is punishable by law. The consequences for driving under the influence (DUI) include:
- Up to five years in prison or a fine of up to 1 million yen.
- License revocation and a mandatory rehabilitation program.
- Employer liability, meaning passengers, car owners, and even bars serving alcohol to drivers may also face legal consequences.
Despite these harsh penalties, drunk driving still accounts for a small but deadly percentage of car accidents in Japan. In 2023, alcohol-related crashes resulted in over 150 fatalities, with most occurring late at night. To further deter DUI offenses, random breathalyzer tests and public awareness campaigns have been intensified.
Intersection and Pedestrian-Related Car Accidents in Japan
Intersections are among the most dangerous locations on Japanese roads, accounting for over 40% of all car accidents in Japan. Many collisions occur due to:
- Failure to yield to pedestrians at crosswalks.
- Running red lights or making unsafe turns.
- Limited visibility at narrow intersections, especially in older urban areas with tight roads.
Pedestrian-related accidents are particularly high in Tokyo, Osaka, and other major cities, where foot traffic is dense. Elderly pedestrians are the most vulnerable, often misjudging crossing times or struggling with oncoming vehicle speeds.
How does Japan compare to other countries in terms of road safety?
When it comes to road safety, Japan consistently ranks as one of the safest countries, boasting a lower traffic fatality rate compared to both the United States and many European nations. In 2023, Japan recorded 2,678 traffic deaths, translating to approximately 2.14 fatalities per 100,000 people. This is significantly lower than the U.S. where the rate was approximately 12.4 fatalities per 100,000 people in 2022, and also lower than the European Union’s average of 5 fatalities per 100,000 people.
While Japan’s overall road safety is impressive, its aging population and the recent uptick in accidents highlight the need for continued efforts to improve safety.
The U.S. and European countries face different challenges. In the U.S., drunk driving and speeding are significant contributors to accidents, while many European nations benefit from strong public transport systems that reduce individual car usage and the associated risk of accidents. Japan’s has a combination of high vehicle density and advanced road infrastructure gives it a relatively low accident rate despite these challenges.
Impact of Car Safety Technology
Japan uses advanced car safety technologies, which play a big role in its low accident rates. Such as collision avoidance systems, automatic emergency braking, lane-keeping assist, and adaptive cruise control are widely used in both new and used cars. These systems help mitigate human errors by assisting drivers in dangerous situations and preventing collisions before they happen.
In addition, Japan has introduced vehicle-to-everything (V2X) communication, which allows cars to interact with infrastructure (traffic lights, road signs) and other vehicles to improve traffic flow and reduce the risk of car accidents in Japan. Also, Japan has strict regulations that require car manufacturers to install certain safety features in all new vehicles, ensuring that the majority of cars on the road meet high safety standards.
Government Regulations and Driver Education
The Japanese government constantly trying to maintain high road safety standards through strict regulations and comprehensive driver education programs.
- Driver’s licenses in Japan are earned after passing a series of tests, including written exams, practical driving tests, and health evaluations. The process ensures that only qualified drivers are allowed on the road.
- Traffic law enforcement in Japan is rigorous, with frequent checks for speeding, drunk driving, and distracted driving. The use of traffic cameras and random DUI checkpoints further deters reckless driving.
- Japan also runs regular traffic safety campaigns to promote awareness, particularly targeting vulnerable road users like the elderly and pedestrians.
These efforts contribute to Japan’s impressive safety record but must adapt to evolving challenges, such as the growing number of elderly drivers and increased reliance on autonomous driving technologies.
In comparison, many countries face greater difficulties with driver education, inconsistent law enforcement, and lax regulations, leading to higher accident rates. However, as nations worldwide adopt more advanced technologies and stricter regulations, Japan’s leadership in road safety to be honest, remains a model for other countries to follow.
What Are the Best Ways to Prevent Car Accidents in Japan?
For foreigners driving in Japan, it is really important to understand local traffic laws and adjust driving behaviors accordingly to reduce the risk of accidents. Japan’s traffic rules can differ significantly from other countries, and failing to adhere to them can lead to accidents or fines.
Here are key safe driving practices for foreigners:
- Adhere to speed limits: Speeding is one of the most common causes of car accidents in Japan. Always pay attention to posted speed limits, which can change depending on the area, and avoid driving too fast, especially on unfamiliar roads.
- Drive on the left side of the road: Japan follows left-hand driving, meaning drivers should always keep to the left lane and yield to the right for overtaking vehicles.
- Use seat belts at all times: Japan has stringent seatbelt laws for all occupants of the vehicle, including rear passengers. Ensure that everyone in the car is buckled up, regardless of where they sit.
- Respect pedestrians: Pedestrian right-of-way is strictly enforced in Japan, and accidents involving pedestrians are common. Always yield at crosswalks and slow down when driving in busy areas.
- Avoid using your mobile phone: It is illegal to use a phone while driving unless using a hands-free device. Inattention caused by smartphone use has contributed to numerous accidents.
- Familiarize yourself with Japanese road signs: Some signs may be different from those in your home country. Learn to recognize key signals, including those indicating no-entry zones, parking restrictions, or warning of sudden curves. We have included the necessary signs in our traffic laws in Japan guide.
Foreign drivers must also have a valid International Driver’s Permit (IDP) in Japan, which allows them to drive legally for a short period. Many car rentals (if you are renting) will require this as part of their terms and conditions.

Practise Defensive Driving
Defensive driving is a proactive approach to driving that focuses on anticipating potential hazards, staying aware of surroundings, and making safe decisions to avoid car accidents in Japan. Especially, if you are crossing perfectures, road conditions can change quickly.
- Maintain a safe following distance: Always leave sufficient space between your vehicle and the one in front to allow for sudden stops or slowdowns..
- Be aware of blind spots: Japan’s narrow roads and tight intersections often make it difficult to see other vehicles. Always check your mirrors and look over your shoulder when changing lanes or turning.
- Avoid aggressive driving: Whether it’s tailgating, speeding, or erratically changing lanes, aggressive driving is not only dangerous but also increases the chance of accidents. Stay calm, patient, and focused at all times.
- Adapt to weather conditions: Always adjust your driving style to match weather conditions. In rainy or snowy weather, reduce your speed, maintain greater distance, and use fog lights when necessary.
Government Initiatives to Reduce Car Accidents in Japan
Japan’s aging population i would say is the main factor driving the country’s traffic safety efforts. With an increasing number of elderly drivers, there are growing concerns about car accidents in Japan caused by age-related issues such as slower reaction times, vision impairments, and cognitive decline. Japan has introduced stringent laws and innovative programs specifically designed to address elderly driver safety.
- Mandatory Health and Vision Tests: Drivers aged 70 and older must take regular health screenings and vision tests every three years to renew their driver’s license. Similar to Shaken. The tests assess physical and mental fitness to ensure that elderly individuals are still capable of safely operating a vehicle. If a driver fails the health screening, they are given the opportunity to undergo rehabilitation and may be required to take remedial driving lessons before their license is renewed.
- Rehabilitation and Education Programs: For elderly drivers who show signs of reduced ability, Japan has implemented driver rehabilitation courses aimed at improving skills and raising awareness of risks. The government also encourages elderly drivers to voluntarily surrender their license if they feel they are no longer able to drive safely.
- Innovative Safety Features for Elderly Drivers: To accommodate elderly drivers, the government has incentivized car manufacturers to produce vehicles with elderly-friendly features such as larger mirrors, easy-access seats, and automatic parking assistance.
Public Awareness Campaigns and Education
Public awareness is a cornerstone strategy to reduce car accidents in Japan. The government’s traffic safety campaigns and education programs target a wide range of road users, from young children to elderly pedestrians.
- Biannual Traffic Safety Weeks: Every spring and autumn, Japan runs nationwide Traffic Safety Campaign Weeks, during which local authorities, schools, and community organizations engage in educational activities. The Aim of campaigns focus on raising awareness of drunk driving, speeding, distracted driving, and the dangers posed to pedestrians, especially in urban areas. Public service announcements, workshops, and outreach events are organized to educate people on the importance of responsible driving.
- Driving Schools and Defensive Driving Courses: Japan places a strong emphasis on defensive driving education. All drivers, from young drivers to seniors, are encouraged to take defensive driving courses to better understand how to react to potential hazards. These courses teach drivers to anticipate risky situations and avoid making impulsive decisions. The focus is not only on technical skills but also on fostering an understanding of the human factors that lead to car accidents in Japan.
- Pedestrian Safety Education: Japan’s school programs educate children from an early age on pedestrian safety the importance of crossing at designated areas, looking both ways, and being cautious of vehicles. Public outreach programs also target elderly pedestrians, encouraging them to cross safely and avoid distractions like smartphones when on the road.
