Why cars from Japan?
Low mileage
A private car in Japan is driven on average 9300 km per year, while the
equivalent mileage in Europe is 15000 km. The explanation for this is
that the Japanese public transport system is one of the greatest in the
world, and thus the Japanese people simply don't need to use their cars
that much. Condition is great
Japanese people are very caring about their personal belongings. They keep their cars in great condition, and maintenance as per manufacturers service schedule is prioritized. The Japanese Shaken (車検) test, Japan's equivalent to Finland's annual vehicle inspection, is mandatory. This means that all cars are to be kept in good condition in order for the owners to be allowed to use them.
Equipment level
Cars that are imported into Japan through official dealers have a very high equipment level. The level of equipment at least equals, or is even better than, that of European countries such as Germany.
Road conditions and road salt usage
The roads in Japan have a very high standard compared to European roads, and therefore the wear and stress on cars and their chassis components is also less. Further on, despite there are snowy regions in Japan, the use of road salt is very minimal compared to Europe, especially northern Europe, meaning that rust on cars is a rare sight.
