JDM Vehicle Characteristics Include:

The term “Japanese domestic market” (“JDM“) refers to Japan’s home market for vehicles and vehicle parts. Japanese owners contend with a strict motor vehicle inspection and grey markets. JDM is also used as a term colloquially to refer to cars produced in Japan but sold in other countries. JDM does not necessarily refer to the market that the vehicle is destined for.

The average age of JDM cars is 8.7 years, ranking 9th in a survey of 30 of the top 50 countries by gross domestic product. According to the Fédération Internationale de l’Automobile, a car in Japan travels a yearly average of over only 9,300 kilometres (5,800 mi), less than half the U.S. average of 19,200 kilometres (11,900 mi).

Japanese domestic market vehicles may differ greatly from the cars that Japanese manufacturers build for export and vehicles derived from the same platforms built in other countries. The Japanese car owner looks more toward innovation than long-term ownership which forces Japanese carmakers to refine new technologies and designs first in domestic vehicles. For instance, the 2003 Honda Inspire featured the first application of Honda’s Variable Cylinder Management. However, the 2003 Honda Accord V6, which was the same basic vehicle, primarily intended for the North American market, did not feature VCM, which had a poor reputation after Cadillac’s attempt in the 1980s with the V8-6-4 engine. VCM was successfully introduced to the Accord V6 in its redesign for 2008.

In 1988, JDM cars were limited by voluntary self-restraints among manufacturers to 280 PS (276 hp; 206 kW) and a top speed of 180 km/h (112 mph), limits imposed by the Japan Automobile Manufacturers Association (JAMA) for safety. The horsepower limit was lifted in 2004 [citation needed] but the speed limit of 180 km/h (112 mph) remains.

Motorcycle power and speed restrictions:

For many years Japan had severe restrictions on the maximum power and speed that motorcycles could have.

All motorcycles for the Japanese domestic market were restricted to 180 km/h (112 mph).

Power restrictions were as follows 


  • 250cc class: 45 hp (46 PS; 34 kW)
  • 400cc class: 60 hp (61 PS; 45 kW)
  • 750cc class: 77 hp (78 PS; 57 kW)
  • over 750cc: not allowed


  • 250cc class: 40 hp (41 PS; 30 kW)
  • 400cc class: 53 hp (54 PS; 40 kW)
  • 750cc class: 77 hp (78 PS; 57 kW)
  • over 750cc: allowed, but restricted to 100 hp (101 PS; 75 kW)


Japanese carmakers do not use a vehicle identification number as is common overseas. Instead, they use either a frame number, chassis number, or vehicle ID number and also a model code as well as an emissions code to identify their vehicles. The frame number identifies the vehicles model and serial number. For example, frame number SV30-0169266 breaks down as “SV30” identifying the model as Toyota Camry/Vista and “0169266” being the serial number of the vehicle. The model code designates the vehicle’s model number and features. As an example, ST205-BLMVZ breaks down as “ST205”, which means it is a third generation Toyota Celica GT-FOUR, and “BLMVZ” which designates a set of features incorporated in the vehicle. The Emissions Code refers to the vehicle’s designated emission standard at the time, usually being placed before the vehicle’s model number, and with the five most commonly used designations being E, GF, GH, ABA, and CBA. These codes are only seen on JDM models and are not present on exported models of the same type. Examples would include E-EK9 or GF-EK9 from the first generation Civic Type R, E-BNR32 from the R32 Skyline GT-R, E-JZX100 from the eight generation Mark II[broken anchor]. Another useful example to help differentiate between pure JDM models and export examples is the code JHMEEG6 on the European Civic VTi models and E-EG6 on the Japanese fifth generation Civic SiR trims. Correct identification of the chassis code using these markers would help prove the authenticity of the model.

Worldwide popularity:


In the ’90s the JDM power restrictions along with license restrictions that made it difficult to be licensed on larger motorcycles resulted in a number of models that were not offered anywhere else in the world, with 250cc and 400cc miniature replicas of the bigger 750cc & 900cc bikes.

At the same time, Japan had particularly tough laws regarding road licensing and sales regulations. Any motorcycle more powerful than 250cc had to take an extensively stringent test every two years.

Combining these factors with a virtually non-existent second-hand market made it economic to export the nearly new bikes abroad where they were eagerly bought and a number of import specialists sprung up to cater for this “grey import” market of relatively inexpensive but interesting motorcycles.

In the later ’90s as Japan’s economy fell into recession it became less profitable to export and Japanese owners held on to their bikes for longer. The last global crash all but ended the “grey import” industry with the big specialist importers closing down.


Ex-Japan Imports are also very common in New Zealand where 59% of vehicles registered on New Zealand roads originated from overseas markets as opposed to 41% of which were delivered NZ-New. Of this, 94% originate from Japan. New Zealand imported an average of 134,834 JDM vehicles per year in the period 2015–2019, the majority of which were Mazda 3 (Axela), Suzuki Swift, Nissan Tiida, Toyota Corolla and Mazda 2 (Demio). Other models popular for importation in previous years include exotic vehicles (Honda Torneo, Nissan Skyline, Nissan Laurel and Toyota Altezza), and kei cars (Suzuki Carry, Daihatsu Move, Subaru R2). Due to the popularity of used imports from Japan, and their relatively poor crash-test ratings, the New Zealand Ministry of Transport is currently investigating tougher restrictions on imported vehicles, most notably on the importation of the Toyota Corolla, Mazda 2 (Demio) and Suzuki Swift.

In 2004, importing JDM cars became popular in Canada as highly sought after vehicles, such as the 1989 Nissan Skyline GT-R, became eligible to import under Canada’s 15-year rule. In contrast, importing grey market vehicles into the United States is much more difficult. To avoid regulatory problems, most private individuals wait until EPA restrictions no longer apply to the desired vehicle, which is done on a rolling 25-year cycle.


Ex-Japan import rolling stocks in all kinds is no exception on this list, although it can be considered as JDM but in special case since this was also intended for Japanese market which were mostly acquired by leading private railway companies across Japan such as Japan Railways, even subways such as Tokyo Metro, Tokyu Corporation, Toei Subway and so forth which was in demand for modernizing railway system in most developing countries such as Indonesia, Thailand, and Myanmar to acquire used trains from Japan rather than procuring brand-new rolling stocks, there are some cases that the management from each respective railway companies in Japan such as Japan Railways are decided to donate them to the oversea country, instead of scrapping them ahead in no time, which is really needed for a major upgrade and sign their agreement that the recipient of the oversea country will pay for its freight expenses and the rest will be free. Here are different categories of used rolling stocks listed which were mostly shipped and operated overseas in different countries.

Retail Shops:

Outside of Japan, there are various shops which they sell various kinds of used items from Japan. Philippines is one of the known countries outside Japan to set up a retail outlet called, “Japan Surplus Shop” which is found in most towns of the country. They used to sell used appliances, furnitures, gadgets, accessories, and even bicycles designed for women, are still much more preferred by local buyers because of being more affordable than buying those newly locally made home furnitures, or even new gadgets which is becoming more dominating mostly coming from China and so forth. Most of these items depending on the condition.

Commercial vehicles:


In the early 1990s, Ex-Japanese buses had been rising popular and been common in the developing cities across Asia such as Manila, Philippines, Jakarta, Indonesia & even Yangon, Myanmar.

Like in the Philippines, direct importers near ports in Subic, Zambales & Cagayan Valley have started their auction business to import quality vehicles preferably from Japan. And then so, most of the clients who are mostly operating bus companies based in Manila, Philippines began their interest to grow their transport business thru buying Japan surplus buses from all cities in Japan which are definitely cheaper than buying brand-new ones which are mostly imported from other countries and some are locally assembled coach bodies but still at an expensive price.

Used buses like in the Philippines also requires to convert from RHD to LHD conversion which is in compliance with the Philippine traffic law called Republic Act No. 8506 entitled “An act banning the registration and operation of vehicles with right-hand steering wheel in any private or public street, road or highway, providing penalties therefor and for other purposes.” A violation of this law is punished by imprisonment for a period from two years, four months, and one day, up to four years and two months, plus a fine of 50,000 pesos (approx. $1,000). And most of the used buses from Japan in Manila, Philippines are mostly operating within the city and intercity travel which are at least 10 years of age after being phased out in Japan.
