Kei Truck Towing Capacity: How Much Can a Mini Truck Actually Pull?
Kei trucks are rated to tow 770 lbs in Japan, but mechanically they can pull 1,000 to 1,760 lbs. Here is every model's real towing and payload capacity, plus hitch setups and safe towing tips.
TL;DR: Japan rates kei trucks at 350 kg (770 lbs) maximum towing capacity. Mechanically, most models can pull 450 to 800 kg (1,000 to 1,760 lbs) in stock form. The Honda Acty and Suzuki Carry top out around 1,000 lbs in real world use. No kei truck comes with a factory hitch, so you will need an aftermarket receiver, and you should never tow above 45 mph. These trucks are not built for boats or campers. They are built for utility trailers, equipment haulers, and farm loads on back roads.
Someone on Reddit watched a Japanese farmer tow a flatbed trailer stacked with produce bales behind a 1995 Daihatsu Hijet. The truck weighed less than the load behind it. The farmer was doing maybe 25 mph on a rural road, completely unbothered, the same way you would be unbothered pushing a shopping cart. That is the kei truck towing experience in a nutshell: surprisingly capable at low speeds, genuinely dangerous if you push the limits.
The problem is that "kei truck towing capacity" is not a simple number. Japan has one answer. Physics has another. And the guy selling you a hitch kit on eBay has a third. Here is the real data, broken down by model, with honest guidance on what you can and cannot pull behind these 660cc workhorses.
The Official Number vs. the Real Number
Japan's keijidosha regulations cap towing capacity at 350 kg (roughly 770 lbs). That is the number printed in service manuals and the number Japanese law enforces. But here is the thing: that 350 kg limit is a regulatory ceiling, not an engineering limit. It exists because Japan taxes and insures kei vehicles as a special class, and part of that classification includes load restrictions.
The mechanical reality is different. According to RealTruck, most kei trucks are mechanically capable of towing between 450 and 800 kg (1,000 to 1,760 lbs) in stock form. The formula is straightforward: take the truck's curb weight, add 55 kg (about 120 lbs) for the driver, and multiply by two. A typical 1,900 lb kei truck works out to roughly 1,000 lbs of towing capacity using that math.
So why the gap between 770 lbs and 1,760 lbs? Because the lower number keeps you legal and safe in Japan. The upper number is what the engine, transmission, frame, and brakes can physically handle before things start going sideways. For a 25 year old import operating on private property or low speed roads in the US, you are somewhere in between.
Towing Capacity by Model
Not all kei trucks tow the same. Engine placement, drivetrain, curb weight, and suspension design all affect how much you can safely pull. Here is the breakdown for the five most common imports, with data compiled from HotCars, manufacturer specs, and owner reports.
Suzuki Carry
| Spec | Value |
|---|---|
| Engine | F6A (657cc, 3-cyl) |
| Power | 38 to 45 HP |
| Curb weight | 1,590 to 1,870 lbs |
| Japan rated towing | 770 lbs (350 kg) |
| Real world towing | 1,000 to 1,200 lbs |
| Payload capacity | 770 lbs (350 kg) |
The Suzuki Carry is the default recommendation for towing. The F6A engine is legendarily reliable, parts are everywhere, and the front engine layout gives good weight distribution when pulling a load. The 4WD models with low range are the ones you want. The Carry consistently sits at the top of towing capability charts alongside the Acty, and the F6A's parts availability (via suppliers like Amayama) means maintenance under towing stress is straightforward.
Honda Acty
| Spec | Value |
|---|---|
| Engine | E07A (656cc, 3-cyl) |
| Power | 45 HP |
| Curb weight | 1,610 to 1,870 lbs |
| Japan rated towing | 770 lbs (350 kg) |
| Real world towing | 1,000 to 1,200 lbs |
| Payload capacity | 770 lbs (350 kg) |
The Acty's mid engine layout is its secret weapon for towing. With the engine mounted under the bed rather than over the front axle, weight distribution stays more balanced when a trailer is pulling on the rear. The Attack trim with locking differential and low range gearing is the best towing package Honda ever put in a kei truck. Honda discontinued the Acty in 2021, which means the last units eligible for US import (1996 models) are already here.
Daihatsu Hijet
| Spec | Value |
|---|---|
| Engine | EF-SE (659cc, 3-cyl) |
| Power | 40 to 50 HP |
| Curb weight | 1,650 to 1,940 lbs |
| Japan rated towing | 770 lbs (350 kg) |
| Real world towing | 900 to 1,100 lbs |
| Payload capacity | 770 lbs (350 kg) |
The Daihatsu Hijet is heavier than the Carry and Acty, which cuts into towing capacity slightly since the drivetrain is working harder to move the truck's own mass. Still, the Hijet's reputation for durability makes it a solid choice for regular towing duty. The S83P and S110P generations (early to mid 1990s, the ones currently legal to import) are the workhorses of Japan's farming community for a reason.
Subaru Sambar
| Spec | Value |
|---|---|
| Engine | EN07 (658cc, 4-cyl) |
| Power | 48 HP (supercharged: 58 HP) |
| Curb weight | 1,720 to 1,960 lbs |
| Japan rated towing | 770 lbs (350 kg) |
| Real world towing | 900 to 1,100 lbs |
| Payload capacity | 770 lbs (350 kg) |
The Subaru Sambar is the only kei truck with a four cylinder engine, and the supercharged variants deliver noticeably more torque than the competition. That extra grunt helps at low speeds when pulling a trailer from a standstill. The trade off is the Sambar's rear engine layout, which puts more weight over the rear axle and can make the front end light under towing loads. Subaru stopped producing their own Sambar in 2012, rebadging Daihatsu Hijets after that.
Mitsubishi Minicab
| Spec | Value |
|---|---|
| Engine | 3G83 (657cc, 3-cyl) |
| Power | 40 to 48 HP |
| Curb weight | 1,680 to 1,940 lbs |
| Japan rated towing | 770 lbs (350 kg) |
| Real world towing | 900 to 1,100 lbs |
| Payload capacity | 770 lbs (350 kg) |
The Mitsubishi Minicab sits in the middle of the pack. Solid 4WD system, decent power, reasonable curb weight. The Minicab does not get the press coverage of the Carry or Acty, but the 3G83 engine is a proven unit and Mitsubishi's Super Low range gives it excellent crawl ratio for pulling heavy loads at walking speed.
Payload Capacity vs. Towing Capacity: Know the Difference
These two numbers get confused constantly, and mixing them up is how you break things.
Payload is the weight you put IN the truck: cargo in the bed plus passengers in the cab. Every kei truck maxes out at 350 kg (771 lbs) under Japanese regulations. That is the combined weight of everything riding on the truck's suspension.
Towing is the weight you pull BEHIND the truck via a hitch and trailer. This load rolls on its own wheels and has its own suspension (the trailer's), so it stresses the truck differently. Towing capacity is almost always higher than payload because the trailer carries its own weight.
GCVWR (Gross Combined Vehicle Weight Rating) is the total of everything: truck curb weight, passengers, bed cargo, and trailer weight. This is the number that actually matters. As SlashGear explained, you calculate safe towing capacity by subtracting your truck's curb weight from its GCVWR. The GCVWR is typically found on the VIN plate.
Here is the critical point: payload and towing capacity are not additive. If you have 400 lbs of firewood in the bed and you are also towing a 600 lb trailer, you are at your truck's effective limit even though neither number alone seems dangerous. The engine, brakes, and frame are absorbing all of it simultaneously.
What You Can Actually Tow
Here is an honest breakdown of what fits within a kei truck's towing envelope and what does not.
Realistic Loads (Under 800 lbs)
These are loads you can tow confidently on back roads and around town at 25 to 40 mph:
- Small utility trailers loaded with mulch, gravel, or topsoil (a 4x6 trailer with 500 lbs of material)
- Lawn equipment trailers (mower, trimmer, blower: typically 400 to 600 lbs total)
- Single ATV or dirt bike on a lightweight flatbed trailer
- Farm produce loads to local markets
- Small boat (Jon boat or kayak trailer: under 500 lbs)
- Dump runs with household debris or yard waste
Pushing It (800 to 1,200 lbs)
These loads are mechanically possible but require caution. Keep speeds under 35 mph, stick to flat terrain, and make sure your brakes are in excellent condition:
- Loaded 5x8 utility trailer (lumber, fencing materials)
- Two ATVs on a tandem trailer
- Small livestock trailer with one or two animals
- Heavier equipment like a compact generator or welder on a cart
Absolutely Not
Do not attempt these regardless of what someone on YouTube claims their kei truck can pull:
- Travel trailers, pop up campers, or any RV
- Full size boats on trailers
- Car dollies or vehicle transport trailers
- Enclosed cargo trailers (the wind resistance alone will overwhelm 45 HP)
- Anything over 1,500 lbs on public roads
As one owner on r/keitruck put it: "You can likely tow more than 400 kg, the question is whether it's legal, and if the cops check it in your country." In the US, there is no federal towing capacity enforcement for vehicles this old, but your insurance company will absolutely care if something goes wrong.
Hitch Setup: What You Need
No kei truck leaves the factory with a tow hitch. You have three options to add one.
Aftermarket Receiver Hitches
The most common approach is a bolt on Class I or Class II receiver hitch designed for kei trucks. Oiwa Garage and a handful of other kei truck parts suppliers sell model specific receiver hitches that bolt to the frame. Expect to pay $150 to $400 for the hitch itself, plus installation.

Make sure the hitch bolts to the frame, not the bumper. Kei truck bumpers are cosmetic, not structural. A bumper mounted hitch will rip off under load and potentially send your trailer into oncoming traffic.
Custom Fabrication
Some owners weld a custom hitch plate to the frame. This gives you more flexibility on positioning and weight rating, but it requires a competent welder and knowledge of the truck's frame stress points. Cost: $200 to $500 at a local fabrication shop.
Pintle Hook or Clevis
For farm and property use where you are towing at low speeds, a pintle hook or clevis hitch mounted to the frame works fine. These are simpler, cheaper ($50 to $150), and commonly used on Japanese farm equipment. The downside is they rattle more than a ball hitch at road speeds.
Safe Towing Tips for Kei Trucks
Towing with a 660cc engine and a 1,900 lb truck is fundamentally different from towing with a 5.0L F-150. The margin for error is much smaller. Here is how to stay out of trouble.
Keep speeds under 45 mph. The engine cannot sustain high RPM under load for extended periods without overheating. Most kei truck owners who tow regularly report staying between 25 and 40 mph as the sweet spot.
Use a trailer with its own brakes. At 1,900 lbs, your kei truck does not have enough braking force to stop both itself and a heavy trailer from 40 mph. Electric trailer brakes are a $200 to $400 addition that could save your life. As NHTSA's trailer safety guidelines make clear, any vehicle towing near its rated capacity needs independent trailer brakes to maintain safe stopping distances.

Upgrade your mirrors. Kei truck mirrors are tiny. Add clip on towing mirror extensions so you can see past the trailer. They cost $20 to $40 and clamp to your existing mirrors.
Check your tires. Most kei trucks run 12 inch tires with sidewalls designed for light loads. If you are towing regularly, upgrade to a load rated tire. Consult our tire guide for model specific recommendations.
Stay off highways. This is not just a legal recommendation in many states. At highway speeds, the aerodynamic drag from a trailer can exceed the engine's available power, and crosswinds become genuinely dangerous with a vehicle this light. Back roads and county roads are where kei trucks belong when towing.
Inspect your brakes before every tow. Kei truck drum brakes wear faster under towing loads. Check pads, drums, and brake fluid before hooking up a trailer. Our maintenance guide covers the full brake inspection process.
Go 4WD. If your truck has part time four wheel drive, engage it when towing on loose surfaces, gravel, wet grass, or hills. The added traction makes a real difference when pulling 800 lbs up a dirt road. Two wheel drive kei trucks can tow, but they spin tires on anything less than dry pavement.
Kei Truck vs. UTV: Which Tows Better?
Since kei trucks compete directly with UTVs and side by sides on farms and properties, this comparison comes up constantly. The short answer: kei trucks tow about the same weight as a mid range UTV but do it from an enclosed cab with a heater and on street legal tires.
According to UTV Driver, the Polaris Ranger 570 tows 1,500 lbs, the Honda Pioneer 700 tows 1,500 lbs, and the Can-Am Defender tows 2,000 lbs. Those numbers are all higher than a kei truck's practical limit. But a Polaris Ranger costs $13,000 new, requires a trailer to get anywhere off your property, and leaves you exposed to weather. A kei truck costs $5,000 to $8,000 used, drives on public roads, and has a cab with a radio and a heater.
For a deeper breakdown, read our kei truck vs UTV comparison. The towing capacity gap narrows significantly when you factor in a UTV's $300 per year insurance, its inability to drive between job sites, and the cost of the truck and trailer needed to move it around.
When Towing Kills the Value Proposition
Let's be honest about the limits. If your primary need is towing, a kei truck is the wrong vehicle. These trucks exist because they are cheap, tiny, fuel efficient utility haulers. Towing is a bonus feature, not the core use case.
If you regularly need to tow over 1,500 lbs, buy a used half ton pickup. As MotorTrend has documented, kei trucks shine at utility hauling, not heavy towing. If you need to tow 3,000+ lbs, buy a three quarter ton. The kei truck's strength is doing everything ELSE: running errands on your property, hauling feed and tools in the bed, navigating barn aisles and orchard rows, and occasionally pulling a small trailer to the dump or the farmers market.
The best kei truck owners think of towing capacity as an emergency reserve, not a daily spec. You CAN tow 1,000 lbs. You SHOULD plan your workload so you rarely need to.
The Bottom Line
A kei truck can tow 1,000 to 1,200 lbs in real world conditions, roughly the same as a subcompact crossover. That is enough for a utility trailer, a small equipment hauler, or a single ATV on a flatbed. It is not enough for campers, boats, or anything you would normally see behind a pickup truck.
The keys to safe kei truck towing: aftermarket hitch bolted to the frame (never the bumper), trailer brakes for anything over 600 lbs, speeds under 45 mph, and 4WD engaged on anything that is not dry pavement. Stay within those parameters and these little trucks will surprise you with what they can move. The r/minitrucks community is full of owners sharing their towing setups and real world load tests.
If you are still shopping, start with our pre purchase checklist and check whether your state allows kei trucks on public roads via our state legality guide. And if you already own one, the off road mods guide covers suspension upgrades that will improve towing stability too.
