Why Japanese Used Cars are Value for Money?

Japanese cars can be around 30-50% cheaper to buy new in Japan, than in most other countries.

When a vehicle is first registered in Japan, it comes with a 3 year 'Shaken' (pronounced: 'shar-can'). 

When the 'Shaken'  expires, the vehicle must be re-tested. This is the most stringent test of this type in the world. The cost for this test is rather high. 

Further re-tests are required every 2 years. There are Japanese dealer incentives offering excellent deals to encourage consumers to always trade up for a new car.

As a result, Japanese consumers buy new cars on a regular basis. About 8 million new units per annum in Japan. Used car values depreciate rapidly in Japan. 

Also, due to the high expense of driving long distances in Japan, cars only tend to cover very low mileages per annum. 

All of the above points make Japanese used cars not only high quality vehicles but also very  economically for export.
