How do I find the year my Japanese import was built?

Japanese-market cars have a chassis (frame) number such as AGH30-0250000 instead of a 17-character VIN. Japan's carmakers publish, through their association JAMA, the chassis number ranges each model was built with every year from 2015. Enter the number above and we find the range it falls in.

Is the build year the same as the year on the V5C?

Not always. The year on a UK record for an import can come from its first registration in Japan, so a car built late in one year can show the next year. A V5C year earlier than the build year is a reason to check the chassis number on the car.

Why can't you date a car built before 2015?

JAMA's lists start with cars built in 2015. For older cars the export certificate gives the first registration date in Japan, and the model guide gives the years the model was built.

A serial inside a listed range gives the year straight from the list. A serial in a gap between two ranges gives the likely year or years, and we say so. JAMA describes the lists as reference information, not a certificate.

What year was my Japanese car built?

Japan’s carmakers publish the chassis number ranges every model was built with each year. Enter a chassis (frame) number, such as AGH30-0250000, to see which year’s range it falls in.

That’s a chassis code without its serial. Here are the ranges JAMA lists for GGH30; add the serial after the hyphen to find the year.

From the JAMA chassis number lists: 車台番号一覧表. We keep only the chassis code, serial ranges and year. JAMA calls them reference information, not a certificate.

To compare it with the car’s UK records, run a free check with its registration: we flag a UK year that comes before the build year. The chassis decoder shows what else the number says.

What the lists cover

Cars built in Japan from 2015 to 2025 by Toyota and Lexus, Nissan, Honda, Mazda, Subaru, Suzuki, Daihatsu and Mitsubishi: 1,182 chassis codes, including cars built for another brand, such as the Toyota 86 that Subaru builds. Lorries and motorcycles are left out. Cars built before 2015, and cars built outside Japan, aren’t in the lists.

Source: the JAMA chassis number lists: 車台番号一覧表, 2015 to 2025, published by the Japan Automobile Manufacturers Association for garages and inspection stations. We keep only the chassis code, serial ranges and year, and update them each year when the new list comes out.
