Kei Truck Import Guide: Which US States Allow Them in 2026

Kei trucks — Japan’s tiny, capable mini work trucks — have gone from obscure curiosity to one of the fastest-growing imported vehicle categories in the United States. US kei truck imports roughly tripled between 2019 and 2024, reaching around 7,500 units in 2024 according to Japan Used Motor Vehicle data reported by CNN Business. But the question that stops most would-be buyers is the same one that matters most: can I actually register one where I live?

What is a kei truck?

A kei truck (kei meaning “light” in Japanese, keitora in full) is a mini truck built to Japan’s kei vehicle class — strict limits including a maximum 660cc engine and compact dimensions that keep the vehicles tiny, light, and extremely efficient. Common models include the Honda Acty, Suzuki Carry, Daihatsu Hijet, Subaru Sambar, and Mitsubishi Minicab.

Despite their size, kei trucks are genuinely useful: a flat or dumping bed, often four-wheel drive, low running costs, and a footprint that fits where a full-size pickup never could. That combination is exactly why farmers, ranchers, landscapers, brewery operators, urban delivery services, and off-road enthusiasts have driven the surge in US demand.

Why kei trucks surged in popularity

The growth is striking. Kei truck imports to the US roughly tripled from 2019 to 2024 — about a 300% increase over five years — reaching approximately 7,500 units in 2024, with tens of thousands now operating across North America.

Kei trucks enter the US under the federal 25-year rule: once a vehicle is 25 or more years old, measured by month of manufacture (not model year), it is exempt from most federal import restrictions. As of January 2026, vehicles manufactured in January 1999 or earlier are eligible, with 1999, 2000, and early-2001 builds rolling into eligibility month by month as the year progresses.

That month-of-manufacture detail matters: a “2000 model year” kei truck built in late 1999 becomes eligible earlier than one built in mid-2000. Always check the build date, not the model year.

The 25-year status carries a second advantage in 2026. A tariff introduced in 2025 added a steep additional duty on imported modern passenger vehicles and light trucks — but vehicles 25 or more years old are exempt, paying only the standard duty rate. For kei trucks, which are only importable because they are old enough, this means they sidestep the higher modern-vehicle tariff entirely. We explain the federal rule and the tariff in detail in our 25-year import rule guide.

Which US states allow kei trucks in 2026?

This is where it gets complicated — and where you must do your own homework before buying. Federal eligibility gets a kei truck into the country; whether you can register and drive it is decided at the state level, and the state landscape is uneven and shifting.

Sources differ on the exact count because rules change frequently and definitions vary. Some industry trackers cite kei trucks as street-legal in roughly 19 states; others count higher as more states clarify or expand access. State treatment falls into three broad buckets:

• On-road registration available — a large and growing group of states permit kei truck registration for road use, sometimes with restrictions (speed limits, no interstates, or specific classifications).
• Restricted or conditional — some states allow kei trucks only as off-road or farm vehicles, limit them to lower-speed roads, or require extra inspection.
• Difficult or disallowed — a smaller number have moved to block or heavily restrict registration, citing safety-standard concerns; several such decisions have been challenged or revised.

Because the count genuinely changes year to year — and a state that disallowed kei trucks one year has sometimes reversed the next — confirm your specific state’s current rule before buying. Check with your state’s DMV or motor vehicle authority and look for the most recent ruling, not an old forum post.

Kei trucks are cheap to buy in Japan, but landed cost determines whether the deal makes sense. The components are the same as any Japanese import: purchase price, auction and exporter fees, domestic transport, ocean freight, marine insurance, US import duty (the lower 25-year-exempt rate), customs clearance, and state registration.

One detail works strongly in the kei truck’s favor: size. Because they are so small, multiple kei trucks fit in a single 40ft high-cube container — commonly four — which splits the largest shipping cost across several vehicles and dramatically lowers per-truck freight. For importers, that container math is the heart of the kei truck’s appeal: more units, more margin, per container.

How to buy a kei truck from Japan

1. Confirm your state allows it — before anything else.
2. Target the right build date — manufactured January 1999 or earlier for eligibility in early 2026 (check the month, not the model year); later-1999 and 2000 builds become eligible as the year progresses.
3. Find the truck — through an exporter or platform, via auction or fixed-price listing.
4. Read the auction sheet — kei trucks are work vehicles, so check honestly for rust, bed wear, and 4WD function. Our auction sheet guide shows you how, and the Auction Sheet Decipher translates it.
5. Calculate landed cost — including the container-share savings and the 25-year duty rate.
6. Ship, clear customs, and register — and budget for any state-specific inspection.

Frequently asked questions

Are kei trucks street legal in the US?

It depends on your state. Federally, kei trucks 25 years or older (by month of manufacture) are eligible to import. Whether you can register one for road use is decided by your state — some sources count around 19 states as fully street-legal, with others allowing off-road or farm use, and the landscape changes frequently. Always confirm your state’s current rule.

How much does it cost to import a kei truck?

Used kei trucks typically cost $5,000–$10,000 in Japan, and because several fit in one shipping container, per-truck freight is low. Total landed cost depends on the truck, your state, and shipping method — run your specifics through a landed cost calculator for an accurate figure.

What is the best kei truck to import?

The most popular and well-supported models are the Honda Acty, Suzuki Carry, Daihatsu Hijet, Subaru Sambar, and Mitsubishi Minicab. Target build dates that are at least 25 years old for federal eligibility.

Why are kei trucks subject to the 25-year rule?

Kei trucks were not built to US federal motor vehicle safety standards, so newer ones cannot be road-registered federally. Once a truck is 25 or more years old (by month of manufacture), the federal 25-year exemption applies and it can be imported — and it is also exempt from the higher 2025 tariff on modern vehicles.

How many kei trucks fit in a container?

Commonly four kei trucks fit in a single 40ft high-cube container, which is a major reason they are economical to import in volume — the freight cost splits across all four.

Confirm the rules, then run the numbers

Kei trucks are one of the most rewarding imports available in 2026 — cheap to buy, useful, exempt from the modern-vehicle tariff, and increasingly supported by a real US community. But the two things that decide whether your import works are entirely checkable in advance: does your state allow it, and what is the true landed cost.

Confirm your state’s current rule with your DMV, then run your target truck and state through the Landed Cost Calculator. For the full process, start with our complete guide to importing a car from Japan.
