What Are JDM / Import Number Plates?

If you own a Japanese import car, you’ve probably heard the term JDM number plates. But what exactly does that mean?

JDM stands for Japanese Domestic Market. It covers cars, parts, and styles made for Japan’s market. This includes their number plates.

JDM plates are smaller than standard UK plates. The size fits Japanese cars like Nissan Skyline, Honda Integra, or Toyota Supra. These cars have smaller spaces for plates.

UK standard plates are 520mm x 111mm. JDM plates are usually 330mm x 178mm (13” x 7”) or 330mm x 165mm (13” x 6.5”). They look different but are legal on certain cars in the UK.


Are Japanese Import Plates Legal for UK Roads?

Yes, but only for genuine imports.

The DVLA allows smaller plates on cars that are imported and can’t fit UK plates. You can read the official DVLA rules on Gov.uk.

Your car must:

  • Be an imported vehicle
  • Have no space for a UK-size plate
  • Be registered correctly with the DVLA

If your car meets these points, you can legally fit import size plates with motorcycle-size characters (64mm tall and 44mm wide).

If your car is UK-spec, you must use standard UK plate sizes. Even if you like the JDM look, it’s not legal to fit smaller plates to UK models just for style.

You can find legal JDM plates in various sizes at Official Plates. They offer both standard and import sizes made to UK rules.

The History of JDM Plates in UK Car Culture

JDM plates became popular in the UK with the rise of Japanese imports in the 90s and 2000s.

Cars like the Nissan Skyline GT-R, Mazda RX-7, and Toyota Supra didn’t officially sell here. Enthusiasts started importing them.

These cars came with smaller Japanese plates. UK laws changed in 2002 to allow import plate sizes for these cars.

Since then, JDM plates have become part of UK car culture. They show that a car is genuine JDM.


Do Authentic-Sized JDM Plates Affect Vehicle Value or Authenticity?

Yes.

Using correct-size plates helps your car look factory correct. Enthusiasts and buyers often look for details like this.

It shows you care about authenticity. This can help when you sell the car. It keeps the car’s JDM identity intact.


Regional Legal Considerations for JDM Plates Across the UK

While JDM plates are legal on imports, police enforcement can vary.

Some areas check plates more strictly. For example:

  • Wrong font or spacing – might get you stopped
  • Non-reflective plates – illegal
  • Incorrect size on UK cars – illegal

Official Plates recommends carrying proof of your vehicle’s import status. This can help if you get stopped.
