Japanese cars often have remarkably low mileage primarily due to the country's stringent and costly vehicle inspection system, known as the Shaken Law. This regulation significantly influences car ownership duration and incentivizes owners to replace vehicles frequently.
The Impact of Japan's Shaken Law
In Japan, it is quite common for used cars, particularly non-commercial passenger vehicles, to have low mileage. This trend is a direct result of the nation's unique automotive culture and strict regulatory environment. The Shaken Law plays a pivotal role in this phenomenon.
Usually, after a vehicle has been in service for about four or five years, it is often put out of service by its owner in Japan. This swift turnover is largely driven by the economics of the Shaken inspection process. Rather than continuing to pay for increasingly expensive inspections and potential repairs required to pass them, many Japanese car owners find it more practical and cost-effective to sell their existing vehicle and purchase a newer one. This practice directly contributes to the low mileage seen on many Japanese used cars, as they are retired before accumulating significant wear and tear.
Understanding the Shaken Law
The Shaken Law (officially known as the "Motor Vehicle Inspection System") is a mandatory, comprehensive vehicle inspection required by the Japanese government. Its purpose is to ensure vehicles meet rigorous safety and environmental standards.
- Initial Inspection: A new car typically receives its first Shaken inspection three years after registration.
- Subsequent Inspections: After the initial inspection, vehicles must undergo Shaken every two years.
- Cost and Strictness: As a vehicle ages, passing the Shaken becomes progressively more challenging and expensive. Owners face escalating fees for the inspection itself, compulsory liability insurance, weight taxes, and potentially significant repair costs for any issues found during the strict examination. This financial burden often outweighs the perceived value of keeping an older car.
For many owners, the cumulative costs and hassle associated with maintaining an older car to Shaken standards make selling it after a few years a logical economic decision.
Consequences for the Used Car Market
This unique aspect of Japanese car ownership has a profound impact on the global used car market. It creates a steady supply of high-quality, well-maintained, and low-mileage vehicles that are often exported to other countries. This provides an excellent opportunity for international buyers to acquire reliable cars that might have seen limited use on Japanese roads.
| Feature | Explanation |
|---|---|
| Primary Driver | Japan's strict and costly Shaken Law (Vehicle Inspection System) |
| Ownership Cycle | Many vehicles are sold or "put out of service" after 4-5 years |
| Resulting Mileage | Typically low, as cars are replaced before accumulating high mileage |
| Market Impact | Creates a robust supply of high-quality, low-mileage used cars for export |
