Nōhan vs Attack: Best Off-Road Kei Truck?
In short: Both have a factory diff-lock and crawler gear — they are equally capable off-road. The Attack is eligible to import to the US right now. The Nōhan wins on parts availability and easier long-term ownership — but you cannot bring one in until May 2027 at the earliest. If you need the locker today, buy an Attack. If you can wait and want the simpler truck to own, the Nōhan is worth the wait.

The layout argument: front-engine vs mid-engine
The Nōhan's front-engine layout
The K6A sits under the cab at the front of the Carry — conventional, accessible, familiar to any mechanic. An oil change takes 20 minutes. Spark plugs are easy to reach. The Carry handles like a front-heavy truck: predictable on gravel and farm tracks, no surprises. The weight-forward layout means the front tyres work harder on climbs, but the diff-lock compensates when it matters.
The Attack's mid-engine layout
The E07Z sits behind the cab, above the rear axle. This gives the Attack a 45/55 front-to-rear weight distribution unladen — improving further toward the rear with a payload. On soft ground, steep hillsides, and uneven terrain, the Attack is noticeably more planted than the Carry. The mid-engine layout puts weight over the driven rear wheels, where it is most useful when the diff-lock is engaged. The tradeoff: every maintenance job takes more patience, and a mechanic unfamiliar with the layout will charge more time.
US import eligibility — the decisive difference for most buyers
Available now
Honda Acty HA3/HA4 Attack
Produced 1988–1999. Every example is eligible for US import right now under the 25-year rule. The Attack has been importable since 2013. Inventory exists in the US, in Japan, and with export agents. If you want a factory diff-lock kei truck today, this is the only option.
From May 2027
Suzuki Carry DA63T Nōhan
Produced May 2002–2013. The earliest examples become eligible under the 25-year rule from May 2027. No DA63T — Nōhan or otherwise — can currently be legally imported to the US under the standard exemption. Buyers who want the Nōhan are ordering for 2027 delivery or later.
For most US buyers, this is the decision: buy an Attack now, or wait for a Nōhan. There is no third option for a factory diff-lock kei truck that is both currently eligible and a Carry.
Parts availability — long-term ownership reality
K6A / Nōhan
Oiwa Garage, Yokohama Motors, Gold Star Parts, and saxajdmparts all stock deep K6A inventory. The DA63T's 11-year production run and the K6A's use across Suzuki and Mazda OEM platforms means filters, gaskets, sensors, and wear items ship from US warehouses within days. Most mechanics have seen a K6A. Nōhan-specific items (diff-lock actuator, Hi-Lo fork seals) may require Japan sourcing but the core engine is easy.
E07Z / Attack
rightdriveparts.com, Yokohama Motors, and saxajdmparts support the E07Z, but inventory depth is smaller. Some Attack-specific components (mid-engine coolant hoses, diff-lock hardware, low-range internals) need Japan sourcing with 2–4 week lead times. The E07Z's mid-engine position also means some routine items are harder to access than on a front-engine truck. A buyer far from a JDM specialist should factor this in seriously.
Verdict: The Nōhan wins on parts availability by a meaningful margin. For a buyer who does their own work, lives rurally, or wants the lowest long-term cost of ownership, the K6A's parts network is a real advantage. Attack ownership is manageable — it just requires more planning.

Frequently asked questions
Which is better for off-road use — the Nōhan or the Attack?
Both are equally capable in terms of factory equipment: both have a diff-lock and low-range crawler gear. The Attack has a mild handling edge from its mid-engine weight distribution (45/55 front–rear), which improves traction on uneven terrain. The Nōhan is easier to maintain and has a wider US parts network. Off-road capability is essentially a draw; the real differences are in availability and ownership.
Can I buy a Nōhan right now in the USA?
Not legally under the standard 25-year import exemption. The DA63T was produced from May 2002 to 2013 — the earliest examples become eligible from May 2027. The Honda Acty HA3/HA4 Attack (1988–1999) is fully eligible now and can be imported immediately. If you want a factory diff-lock kei truck now, the Attack is your only current option.
Is the Honda Acty Attack hard to find parts for?
It requires more effort than the Suzuki Carry. The K6A (Nōhan engine) has a wider US network — Oiwa Garage, Yokohama Motors, Gold Star Parts, and saxajdmparts all stock deep K6A inventory. The E07Z (Attack engine) is supported by rightdriveparts.com, Yokohama Motors, and saxajdmparts, but inventory depth is smaller and some parts need ordering from Japan with longer lead times. Plan for 2–4 weeks on obscure Attack-specific items.
Does the HA6 or HA7 Acty have a diff-lock like the Attack?
No. This is the most important buyer-education point for Acty shoppers. The third-generation Acty (HA6/HA7, 1999–2009) uses a Real-Time 4WD system — no diff-lock, no low range. Only the second-generation (HA3/HA4) Attack trim has a factory diff-lock. If a seller lists an HA6 or HA7 as having a diff-lock, it has either been aftermarket-modified or the listing is wrong.
Which should I choose — Nōhan or Attack?
If you want a factory diff-lock kei truck right now, buy an HA3/HA4 Attack — it is the only option currently eligible for US import. If you are willing to wait until 2027 and want the easiest long-term ownership (parts, maintenance, mechanic familiarity), the DA63T Nōhan will be the better choice once eligible. Both are excellent off-road trucks. The choice is primarily about timing and ownership philosophy.
