Suzuki Jimny JB64 import check
JB64W is the factory model code for the Suzuki Jimny JB64, built for the Japanese market from 2018 to 2026. Other versions carry JB74W. Every genuine car has a chassis (frame) number that starts with its code, such as JB64W-. That number is the one thing that links its Japanese history to its UK records.

Is it a genuine JB64W?
The UK-market Jimny is the 1.5 with a 17-character VIN. A JB64W is always the Japanese-market kei car with the 658 cc turbo. Suzuki keeps the W in its chassis numbers.
Known problems to check on a JB64W
- Rust on the ladder chassis and rear crossmember from salted roads
- Steering shimmy (often called death wobble) after lift kits or worn steering parts
- Kei cars are built to Japan’s small-car rules (658 cc, 64 PS cap): check it is comfortable at UK motorway speeds before you commit
- High demand means some have finance or theft history: run a full check
These are common issues for the model, not facts about any particular car. Ask the seller about each one.
Before you buy
- Look under the car at the chassis rails and rear crossmember
- Check the four-wheel drive and low range engage
The JB64W on a Japanese auction sheet
- The sheet names the car ジムニー (Jimny), or ジムニーシエラ for the Sierra.
- Cars from snowy northern Japan can have more underbody rust than the auction grade suggests: look underneath before you buy
Most imports were bought at a Japanese auction, and the inspector’s sheet records the grade, mileage and every mark on the body. Ask the seller for it, then run it through our auction sheet translator to read it in English and check the chassis number and mileage against the UK record.
Recalls in Japan for the JB64W family
Japan publishes every recall with the chassis numbers it covers. Run a recall check with the car’s chassis number to see whether any apply to it.

Kilometres, miles and the first UK MOT
A JB64W sold new in Japan has a speedometer in kilometres. When it is imported, the speedometer is either converted to miles or left in km, and the first UK MOT should record whichever the dial shows. Mistakes here are common, and they’re where mileage problems hide.
We put the Japanese auction mileage and every UK MOT reading on one timeline and check the crossing: whether the readings agree after converting, whether the km figure was written down as miles, and whether the first UK reading is lower than the car had already done in Japan. See an illustrative example.
Questions
What is the chassis code for the Suzuki Jimny JB64?
JB64W, with JB74W for other engines or drive layouts. A Japanese-market Suzuki Jimny JB64 has a frame number that starts with its code, then a hyphen and a serial number. You’ll find it on the V5C and on a plate in the engine bay.
Which years was the JB64W built?
From 2018 to 2026, with the R06A (658 cc turbo petrol) engine and Part-time 4WD layout.
What should I check when buying a JB64W?
Rust on the ladder chassis and rear crossmember from salted roads. Steering shimmy (often called death wobble) after lift kits or worn steering parts. Kei cars are built to Japan’s small-car rules (658 cc, 64 PS cap): check it is comfortable at UK motorway speeds before you commit. High demand means some have finance or theft history: run a full check. Look under the car at the chassis rails and rear crossmember. Check the four-wheel drive and low range engage. Also check that the Japanese auction mileage lines up with the first UK MOT, because km and miles are easily mixed up.
