A kei truck is one of the most useful vehicles you can put on a farm, ranch or big property, and one of the easiest to buy wrong if you don't know what to look for. A kei truck you can register for the road in the U.S. is an imported Japanese work truck at least 25 years old, so the buying process is different from walking onto a dealer's lot. This guide covers what we tell buyers at our Houston lot: what a kei truck is, how importing works, how to choose one, what to inspect, and what paperwork and titling look like.
What is a kei truck?
"Kei" is short for kei jidōsha, Japan's light-vehicle class. Kei vehicles get tax and insurance breaks in Japan in exchange for strict size and engine limits. Since 1990 the rules have been:
- Engine: 660cc maximum. Most kei trucks have a three-cylinder engine (the Subaru Sambar uses a four-cylinder).
- Size: no more than 3.4 m long and 1.48 m wide (about 11.2 × 4.9 ft) since October 1998. Earlier trucks had to fit 3.3 × 1.4 m.
- Load: a maximum load rating of 350 kg, about 770 lb.
- Power: Japanese makers agreed to cap kei engines at 64 PS (63 hp). The kei trucks we sell make roughly 37 to 59 hp.
In practice that gets you a small cab-over truck with a full-width flat bed. On a 1999–2001 Suzuki Carry, for example, the bed measures 1,940 × 1,410 mm (about 6.4 × 4.6 ft), according to Suzuki's catalog. Every kei truck is right-hand drive, and the odometer reads in kilometers.
Why the trucks are 25 years old
Kei trucks were never built to U.S. safety and emissions standards for new vehicles, so they can't be imported new. Federal rules make two exceptions that matter:
- Safety (NHTSA): a vehicle at least 25 years old, counted from its month and year of manufacture, can be imported without meeting the Federal Motor Vehicle Safety Standards. It's declared on DOT Form HS-7.
- Emissions (EPA): a vehicle at least 21 years old and in its original configuration is exempt from EPA import requirements. It's declared on EPA Form 3520-1.
So in 2026, the trucks you can buy were built in 2001 or earlier, and late-2001 trucks only become eligible as their build month passes. Treat any seller offering a "2010 kei truck" for road use with real caution.
Choosing a model
Four kei trucks make up most imports, and each has its own personality:
- Daihatsu Hijet: the most common, with Jumbo extended-cab, dump and farm versions.
- Suzuki Carry: Japan's best-selling truck nameplate from 1971 to 2009, with 4x4 high/low range.
- Honda Acty: a mid-mounted engine and "real-time" automatic 4WD. The Attack grade adds an ultra-low gear and a rear diff lock.
- Subaru Sambar: a rear-mounted four-cylinder and independent suspension at all four wheels.
We compare them side by side in Hijet vs. Carry vs. Acty vs. Sambar. If you want a small 4x4 with a roof rather than a bed, look at the Suzuki Jimny.
2WD or 4x4?
For pasture, gravel, mud, hunting leases and anything off pavement, buy a 4x4. Most kei 4x4s use part-time four-wheel drive that you switch on when you need it, and some add low range, an extra-low gear or a differential lock, depending on the model and grade. A 2WD truck is lighter, simpler and cheaper, and it works well in warehouses, on job sites and on paved roads.
Manual or automatic?
Most kei trucks are 5-speed manuals, but 3-speed automatics were offered too. One catch: on the Honda Acty truck, the automatic was only offered with 2WD.
Bed, dump, Jumbo or van?
- Standard bed: the most versatile.
- Dump: a tipping bed for gravel, dirt, mulch and feed.
- Jumbo (Hijet): an extended cab with room behind the seats, at the cost of a shorter bed.
- Kei van: enclosed and lockable, for tools or deliveries.
What to inspect
A 25-year-old work truck will show its age. You're looking for problems that cost real money, not cosmetic wear.
- Frame and rust. Look under the truck at the frame rails, crossmembers and leaf-spring hangers, then the cab corners, floor and bed. Surface rust is normal. Holes, flaking frame metal or rot near suspension mounts are not.
- Timing belt. The 1990–2001 Hijet, Carry, Acty and Sambar engines all use timing belts. If there's no record of a change, budget for one, along with a water pump where it's driven by the belt.
- Cooling. Check the coolant level and color, and watch the temperature gauge on a test drive. On the Acty and Sambar the radiator is up front and the engine is in the middle or rear, so long coolant lines run under the truck.
- 4WD. Engage 4WD on loose ground and make sure the front wheels pull. On the Suzuki Carry, the front axle engages by vacuum through a solenoid pack, which is a known trouble spot.
- Clutch and gearbox. A slipping clutch, a very high engagement point or grinding shifts mean work ahead.
- Tires, brakes and fluids. Tires may be old even with good tread. Plan on fresh brake fluid, coolant and oils after import.
- Lights, wipers and horn. They matter if you plan to register the truck for the road.
Our model pages have a detailed "what to check" list for each truck: Hijet, Carry, Acty, Sambar and Jimny. Every vehicle we have in Houston can be inspected and test driven at our lot, and you're welcome to bring a mechanic.
Paperwork you should receive
A legally imported kei truck comes with its import paperwork, and you'll need it to title the truck. Expect:
- The Japanese export certificate (export deregistration certificate), with an English translation
- U.S. Customs entry documents, such as CBP Form 7501 or other proof of release
- DOT/NHTSA Form HS-7 and EPA Form 3520-1 import declarations
- The ocean bill of lading
- A bill of sale
If a seller can't produce import paperwork, walk away.
Titling, registration and insurance
Every state treats kei trucks differently, and some limit or don't allow them on public roads, so check with your state's motor vehicle agency before you buy. In Texas, a 2025 law (SB 1816) made kei trucks "miniature vehicles" that can be titled and registered, and driven on public roads once titled and registered if they can comply with traffic laws. Our Texas kei truck title and registration guide walks through the steps: insurance, a law enforcement VIN inspection (Form VTR-68-A), Form 130-U and a visit to your county tax office.
To register a vehicle in Texas you need liability insurance of at least 30/60/25 ($30,000 per injured person, $60,000 per accident, $25,000 property damage). Give your insurer the chassis number from the export certificate and tell them it's a 25-year-old Japanese import.
Buying a truck that's still on the water
Many kei trucks are sold before they land. At Skyline Kei Trucks, vehicles marked In Transit can be reserved with a $1,000 deposit, and the balance is due within 14 days after we tell you the truck has arrived. Vehicles marked In Houston can be bought outright. Arrival dates are estimates, so leave yourself some slack. See how buying works.
Getting it home
You can pick up at our Houston lot, or we can help arrange shipping anywhere in the mainland U.S. through independent carriers, priced by your ZIP code and paid directly to the carrier.
What to expect on the road
With 37 to 59 hp and a light, short-wheelbase body, a kei truck is happiest on farm roads and local streets. Many owners stick to local roads rather than fast highways. If you need to cover long distances at highway speed, a kei truck is the wrong tool.
Quick checklist
- Confirm your state's rules for titling and road use.
- Pick 2WD or 4x4, manual or automatic, and bed, dump, Jumbo or van.
- Check the build date: at least 25 years old.
- Inspect the frame, timing belt records, cooling, 4WD and clutch.
- Make sure the import paperwork comes with the truck.
- Line up insurance and plan your titling visit.
- Arrange pickup or shipping.
