This is the page I would want to read before spending $5,000, so it opens with the answer: California will not register the kei truck you are looking at. Federal law lets you import one at 25 years old. California registration is a separate question, and for anything built from the 1976 model year onward the state’s answer is no.
A correction to an earlier version of this page. I previously wrote that California’s registration exemptions are closed to direct imports outright. That is not what the DMV’s manual says. There is an exemption route, it is written for used direct imports through the 1975 model year, and it is set out below. It does not help a 1990s kei truck, but it is real and I had it wrong.
I research Japan’s used vehicle market from Sapporo. I have no truck to sell you and no reason to soften this. Below is what the DMV’s own procedures manual says, quoted, so you can verify it rather than take my word.
The Short Answer
- Road registration for a 1976-or-newer import: no. The vehicle cannot show FMVSS compliance or California emission compliance, and there is no exemption written for it.
- Through the 1975 model year there is an exemption route, on Form REG 256F — narrow, and mostly for people who moved to California owning the vehicle already.
- Off-highway registration is also refused for a vehicle that cannot be converted. This is the part most articles get wrong.
- The 25-year federal rule does not help here. It exempts a vehicle from federal safety standards for importation, and says nothing about California emission law.
- If you apply and are refused, the DMV is instructed to tell you to remove the vehicle from the state and to flag the record.
- Private-property use needs no registration and is entirely lawful.
- Insurance minimums rose on 1 January 2025 to 30/60/15, which matters if you register in another state and drive here.
What the DMV Manual Actually Says
California’s Vehicle Industry Registration Procedures Manual § 12.050 covers “direct import” vehicles — “vehicles which have been imported and originally manufactured for use in other countries,” which is exactly a Japanese-market kei truck.
The submission list is where it ends for most buyers. Alongside the customs paperwork — the manual accepts CBP forms 7501, 3461, 6059, 3299 or 3311, stamped or endorsed — the applicant must provide:
“Evidence that the vehicle was modified to meet Department of Transportation (DOT) Federal Motor Vehicle Safety Standards (FMVSS). This may be FMVSS labels affixed to the vehicle or a letter from the manufacturer certifying the vehicle meets FMVSS requirements.”
“Evidence that the vehicle was modified to meet U.S. Environmental Protection Agency (EPA) standards and requirements.”
No Japanese manufacturer issues that letter for a 1990s kei truck. The manual then sets out where non-complying vehicles get sent:
“If the application is for registration of a 1968 year model or newer auto or commercial vehicle…that does not comply with: U.S. emission requirements, refer the applicant to CARB…FMVSS, refer the applicant to the manufacturer to obtain a letter stating the vehicle meets FMVSS.”
And the sentence that closes the off-highway argument:
“Vehicles that cannot be converted to comply with U.S. safety and U.S. and/or California emission standards cannot be registered for on-highway or off-highway use.”
Other guides tell California readers they can at least register a kei truck as an off-highway vehicle. The manual says otherwise for vehicles that cannot be converted, and a kei truck cannot: it was never built to FMVSS, and the compliance letter does not exist.
The Exemption Route, and Where It Stops
Here is the part I previously got wrong. Section 12.020 is headed “California Noncertified/Direct Import Vehicle Exemptions,” and it does provide for direct imports:
“For a used direct import vehicle more than two years old upon date of entry through 1975 year model and not equipped to meet federal or California emission standards to be registered in California, the applicant must certify to one of the following exemptions on a REG 256F:
— When they acquired the vehicle they were a resident of, or on active military duty in, another state for at least one year where the vehicle was last registered.
— The vehicle must have been certified under a U.S. Environmental Protection Agency Certificate of Conformity and issued an approval letter from the U.S. Department of Transportation.
— The vehicle’s engine displacement is less than 50 cubic centimeters.”
Three things follow, and they matter in this order.
The cut-off is the 1975 model year. Not 25 years, not rolling. A 1998 Suzuki Carry is outside it and always will be, because the line does not move. This is the same structural error Alaska made when it wrote 1981 into a regulation in 2006 — except California’s version is older and has not been fixed.
The workable exemption is for people, not vehicles. “A resident of another state for at least one year where the vehicle was last registered” describes someone who owned and registered the truck elsewhere and then moved to California. It is not a route for a Californian importing directly from Japan. The 50cc limb is for mopeds, and the EPA Certificate of Conformity limb is for vehicles that went through a registered importer.
The instruction about REG 256F in § 12.050 is narrower than it reads. That section tells staff: “Do not accept a REG 256F, REV. 8/2016 or prior revisions. Inform the applicant the exemptions are not applicable to direct import vehicles.” Read with § 12.020, which plainly does provide direct import exemptions, the instruction is about the obsolete revisions of the form and about the exemptions written for federally certified vehicles bought out of state. I read it as a flat prohibition the first time, and that was wrong.
What happens if you apply and are refused
This is the practical fact missing from most coverage, and it is worth knowing before you drive to a field office. Section 12.020 instructs staff, where the applicant does not qualify:
“Do not collect any fees. Pick up any temporary operating permit (TOP) or inventory issued…Advise the applicant that the vehicle must be removed from the state. The applicant may purchase a One Trip Permit (REG 402) or be issued a Vehicle Moving Permit (REG 172) to remove the vehicle from California. Fax the Application for Title or Registration (REG 343)…Verification of Vehicle (REG 31)…for placement of a VLT Stop Reason Code 89 on the vehicle record.”
So a refused application is not a neutral event. It produces a record and an instruction to take the vehicle out of California. That is a reason to settle the question before the truck is in the country, not after.
It does not make private-property use unlawful. No registration is required to run a vehicle on land you own or control, and nothing above changes that. The consequence attaches to applying, not to owning.
The smog line agrees with the 1975 line
For completeness, because people ask whether an old enough truck escapes smog check: Health and Safety Code § 44011(a)(3) exempts “all motor vehicles manufactured prior to the 1976 model-year” from the biennial certificate requirement. The same 1975/1976 boundary, arrived at from the other direction. It is consistent, and it is equally frozen.
Is There Any Other Legal Path?
On paper, one exists. CARB runs certification procedures for used direct-import vehicles through authorized laboratories — the “modifier certified” route in its light-duty certification program. In practice this pathway is used by businesses converting vehicles at scale, not by individuals importing one farm truck, and I have not found a documented case of a kei truck completing it. Treat it as theoretically open and practically closed, and do not build a purchase around it.
What you should not do is register the truck in another state while living in California. Registration follows residency; using an out-of-state address you do not live at is not a loophole, it is a false statement on a state form. Several people in kei truck communities describe doing this. It is their risk to take, and it is not advice this page will give.
The historical plate is a plate, not an exemption
Vehicle Code § 5004 provides Historical Vehicle identification plates for a vehicle “manufactured after 1922, is at least 25 years old, and is of historic interest,” for $25, permanent and never replaced. On its face a 25-year-old kei truck fits the age test.
It does not solve anything, for two reasons. First, § 5004 issues a plate to a vehicle that can be registered; it is not an exemption from the emission certification the DMV manual applies at registration. Second, its own conditions are restrictive: the vehicle must be “operated or moved over the highway primarily for the purpose of historical exhibition or other similar purpose,” subsection (f) defines historic interest as collected and operated “principally for purposes of exhibition and historic vehicle club activities,” and subsection (e) keeps the equipment requirements of §§ 26709, 27150 and 27600 in force. The Horseless Carriage series in the same section is for vehicles built in 1922 or earlier.
Compare Pennsylvania, where the antique plate genuinely is the surviving road route. In California it is decoration on a registration you cannot get.
Insurance
Even though you cannot register the truck here, the number is worth carrying, because California raised it recently and a great many pages still print the old one.
Vehicle Code § 16056(a)(2) provides that for any policy or bond issued or renewed on or after January 1, 2025, the minimum limits are $30,000 for bodily injury to or death of one person, $60,000 for two or more persons in one accident, and $15,000 for property damage. Written 30/60/15. The old 15/30/5 figures in subdivision (a)(1) applied to policies before that date.
Two situations where this bites. If you legitimately reside in another state, register there and drive into California, your policy needs to satisfy the law where you are driving. And if the truck lives on your California property, talk to your insurer about it as property rather than assuming a personal auto policy covers a vehicle it has never been told about.
As everywhere, online quote forms validate VIN length and will reject a Japanese chassis number, so this is a telephone conversation. Ask for agreed-value or stated-value cover rather than actual cash value; there is no book value for a 1999 Japanese-market truck.
What California Owners Actually Do
- Private property only. A kei truck needs no registration to work on land you own or control — farms, vineyards, ranches, orchards, campuses, industrial sites. This is a real and common use in California, and it is entirely legal. You simply cannot take it onto a public road.
- Buy where it can be registered. If you have a second residence or you are considering a move, the 50-state street-legal guide shows which states register kei trucks without restriction. Texas is the most open of the large states; Arizona is the nearest neighbor with no kei-specific restriction, though metro Phoenix and Tucson bring their own emissions program.
- Consider a UTV instead. For California light utility work a side-by-side registered as an OHV has a legal pathway a kei truck does not. It costs more and offers less cab, and the comparison is here — but in this state the legal question decides it.
- Do not wait for the law. Most states that refuse these trucks do so through a titling or road-class decision a legislature can reverse in one session — Vermont opened in July 2026 and Alaska reversed itself in June 2026 without a single no vote. California’s obstacle is an emission certification regime with its own standards, laboratories and statutory authority, applied to a vehicle no manufacturer will certify. That is a different kind of wall.
For Reference: What These Trucks Cost
If you are planning around a property vehicle, or a purchase in another state, here is the Japan-side market. Measured August 19, 2026, drawn from truck listings published in Japan, at ¥159/USD:
| Model | Listings measured | Median price in Japan |
|---|---|---|
| Subaru Sambar | 78 | ¥364,000 (≈$2,289) |
| Mitsubishi Minicab | 64 | ¥394,000 (≈$2,478) |
| Honda Acty | 80 | ¥398,000 (≈$2,503) |
| Suzuki Carry | 99 | ¥399,000 (≈$2,509) |
| Daihatsu Hijet | 60 | ¥453,000 (≈$2,849) |
Landed cost runs about $4,800–6,700 depending on specification. The kei truck cost guide itemizes it and the dataset is published so you can recount any figure. If the truck is destined for a California property rather than a road, note that use tax is still owed on the purchase — check the current rate with the California Department of Tax and Fee Administration rather than a blog, including this one.

FAQ
Are kei trucks legal in California?
Legal to import and legal to own, not registrable for road use if built from the 1976 model year onward. Federal law permits importation at 25 years old; California registration requires FMVSS or California emission compliance that an imported kei truck cannot demonstrate.
Is there really an exemption for older imports?
Yes, for a used direct import through the 1975 model year, certified on Form REG 256F. The practical limb is for someone who was a resident of another state for at least one year where the vehicle was last registered. It does not reach a 1990s truck.
Can I register one as an off-highway vehicle in California?
The DMV’s procedures manual says vehicles that cannot be converted to comply with US safety and emission standards “cannot be registered for on-highway or off-highway use.” Several other sites say off-highway registration is available. The manual is quoted and linked above; check it yourself before you spend money on that assumption.
What happens if I apply anyway?
The manual instructs staff to collect no fees, retrieve any temporary permit, advise that the vehicle must be removed from the state, issue a One Trip Permit or Vehicle Moving Permit, and place a stop code on the vehicle record.
Does the 25-year rule make my kei truck legal in California?
No. The 25-year rule is a federal exemption from federal motor vehicle safety standards for the purpose of importation. California emission law is separate, and the state applies it to direct imports regardless of age.
Can I use Historical Vehicle plates?
No. Section 5004 issues a $25 permanent plate to a registered vehicle at least 25 years old and of historic interest, used primarily for exhibition. It is a plate class, not an exemption from the certification requirement, and its use conditions are restrictive.
Can I register it in Nevada or Arizona and drive it in California?
Registration follows where you actually live. Using an address you do not reside at is a false statement on a state application, and this page will not recommend it. If you genuinely maintain residence in another state, that state’s rules apply.
Can I use a kei truck on my own land in California?
Yes. No registration is required for use on private property, which is why kei trucks turn up on California farms, vineyards and ranches. The restriction applies to public roads.
