VIN Numbers Starting With J — Built in Japan
A VIN starting with J was built in Japan. Note the wording: built in Japan, not built by a Japanese company. A Honda from Ohio starts with 1, a Toyota from Ontario with 2. The J is about the factory, and the rest of the VIN is about the car.

A VIN beginning with J identifies a vehicle manufactured in Japan. ISO 3779 allots the whole first character J to Japanese production. Common Japanese WMIs include JHM (Honda), JH4 (Acura), JTD and JTM (Toyota), JTH (Lexus), JN1 (Nissan), JM1 (Mazda), JF1 (Subaru) and JA4 (Mitsubishi). Japanese brands also build in North America and Europe, and those vehicles carry the WMI of the country they were assembled in — not J.
Reading a Japanese-built VIN
The first character places the factory. Everything that matters about the individual vehicle comes after it.
- 1Confirm the JJapan holds the entire first character. If position one is J, the vehicle was assembled in Japan, whatever badge it wears.
- 2Separate brand from countryA Japanese-brand car built in Ohio, Ontario or Mexico starts with 1, 2 or 3. Only the factory determines the first character.
- 3Watch for grey importsVehicles imported privately under the 25-year rule — right-hand-drive Skylines, Delicas, kei trucks — are the one case where the J really does signal an unusual paperwork path.
- 4Check the US recordsA Japanese-built car titled in the US sits in the same title and insurance databases as any other. Run the VIN and read them.
What the code tells you
Which line built it
Toyota alone holds JT2, JTD, JTE, JTM and more, split by vehicle class and plant. The WMI is more specific than the nameplate.
The premium sub-brands
Lexus (JTH), Acura (JH4) and Infiniti (JNK) carry their own identifiers rather than sharing the parent brand's.
Motorcycles included
JYA is Yamaha and JKA is Kawasaki. Japanese powersports VINs use the same seventeen-character structure as cars.
Import status is a paperwork question
A J-prefix VIN on a right-hand-drive vehicle may have entered the US under the 25-year exemption, which affects registration in some states.
VINs beginning with J: manufacturer codes
The first three characters of the VIN are the World Manufacturer Identifier. These are the ones you are most likely to meet on a Japanese-built vehicle — a representative list, not a complete one, since a large manufacturer holds many codes across plants and vehicle classes.
| WMI | Manufacturer | Notes |
|---|---|---|
| JHM | Honda | Passenger cars |
| JHL | Honda | SUVs |
| JH4 | Acura | — |
| JT2 | Toyota | Passenger cars |
| JTD | Toyota | Passenger cars |
| JTM | Toyota | SUVs |
| JTE | Toyota | SUVs |
| JTH | Lexus | — |
| JN1 | Nissan | Passenger cars |
| JN8 | Nissan | SUVs |
| JNK | Infiniti | — |
| JM1 | Mazda | Passenger cars |
| JM3 | Mazda | SUVs |
| JF1 | Subaru | Passenger cars |
| JF2 | Subaru | SUVs |
| JA4 | Mitsubishi | SUVs |
| JS2 | Suzuki | — |
| JAL | Isuzu | Commercial |
| JYA | Yamaha | Motorcycles |
| JKA | Kawasaki | Motorcycles |

Japanese brand and Japanese build are two different facts
This is the single most common misreading of the first VIN character. Honda has built cars in Ohio since 1982; Toyota's Kentucky plant opened in 1988; Subaru builds in Indiana, Nissan in Tennessee and Mississippi. Those vehicles are as Japanese in brand as anything from Aichi, and their VINs start with 1, 4 or 5.
Run the logic the other way and it holds too. A vehicle wearing a Western badge can start with J if a Japanese plant built it under contract, and Japanese-built Mazdas have been sold under multiple names in North America over the years.
So if the question you are actually asking is "is this a Japanese car", the first character will not answer it reliably. If the question is "was this specific unit assembled in Japan", it answers it exactly.
The one case where a J genuinely changes the paperwork
Most J-prefix vehicles in the United States were imported by the manufacturer, homologated to federal standards, and sold new by a franchised dealer. Nothing about them is unusual.
The exception is the private import. US federal rules generally exempt a vehicle from FMVSS conformity requirements once it is 25 years old, which is why right-hand-drive Japanese-market cars — Skylines, Land Cruisers, Delica vans, kei trucks — arrive in a steady stream and always carry J-prefix VINs.
These vehicles are legal, but their paperwork path is different: customs entry documents, a state title issued against a foreign-market VIN that may be shorter or formatted differently, and in some states additional inspection. If you are buying one, the VIN check matters more than usual, not less — you want to see exactly what the US title record says before money moves.
Frequently Asked Questions
What does a VIN starting with J mean?
The vehicle was assembled in Japan. ISO 3779 allots the entire first character J to Japanese manufacturing.
Does a Honda or Toyota always have a VIN starting with J?
No. Both build extensively in North America, and those vehicles carry US, Canadian or Mexican WMIs starting with 1, 2, 3, 4 or 5. The first character reflects the assembly plant, not the brand's home country.
Are Japanese-built cars better than US-built ones?
The VIN encodes nothing about quality, and both are built to the same model-programme specifications. Condition, maintenance and history vary by individual vehicle, which is what a history report shows.
Can I check the history of an imported Japanese vehicle?
If it has been titled in the United States, yes — US title and insurance records are keyed to the VIN. Records from the vehicle's life in Japan before import are generally not available in US databases.
