What goes wrong with Japanese imports, and how each one is avoided
Every problem on this list has cost someone real money. None of them is bad luck; each has a check that prevents it, and most of the checks happen before the bid.

Before the bid: the car itself
Buying from photographs is how most of the bad stories start. The auction sheet exists to prevent it: the overall grade, the interior and exterior grades, the body map with every dent and repaired panel, and the inspector’s notes, all of which need translating properly rather than skimming. A grade R car has been repaired after an accident; it is not necessarily a bad car, but it is a cheaper one and should be bought as one.
The chassis-number history is the second check: the mileage at every previous auction, the grades the car was given before, and how often it has been through the halls. Mileage that goes down, or a car that appears at auction every few months, is the record telling you something. Cars from the snowy prefectures carry underbody corrosion from road salt; ask for underside photographs or a pre-bid inspection. And know the variant you are bidding on: a GR Yaris RC is not an RZ, a Prado TX is not a TX-L, and the price difference is real.

Before the bid: the paperwork that sets the tax
Five paperwork mistakes account for most of the money lost on Irish imports, and the calculator warns about every one of them. Bidding before the exporter has confirmed the Statement on Origin means 10% duty on a Japanese-built car, and VAT on the duty too. Assuming a German-built car bought in Japan is treated as Japanese means the same 10%, with no document that can fix it. Buying a Japan-only model with no plan for the CO2 evidence means the 41% band is assumed at the NCTS until a disclosure comes back. Buying a diesel with no route to its NOx figure means the €4,850 default. And guessing the Irish value low means meeting Revenue’s valuation on the day, when it is too late to change your mind.
For a car near 30 years old there is a sixth: the date. The vintage rate applies from the first registration in Japan on the export certificate, counted to the month. A car that is 29 years and ten months old on the day it is registered pays 41% of its valuation; two months later it would have paid €200.
Between the hammer and the ship
The exchange rate moves between the bid and the transfer. The calculator applies a 2% buffer for exactly this, but a 5% swing on a ¥1,300,000 car is about €360, and on a ¥9,000,000 Supra about €2,500. Pay promptly, and if the rate matters, ask your bank or a currency broker for a forward rate on the day you win.
Exporter fees surprise people who did not get the schedule in writing: the auction fee, inland transport, deregistration, the export certificate, the radiation check, storage if the payment or the sailing slips. Ask for the full schedule before the first bid, replace the calculator’s default Japan-side fees with it, and pay inside the exporter’s window, because storage at a Japanese yard is charged by the day.
At the port
The expensive port problems are all the same problem: the customs broker did not have the file before the ship docked. The exporter’s invoice, the export certificate and its certified translation, the Statement on Origin and the bill of lading should be with the broker a week before arrival, along with your EORI number, which takes days to issue and cannot be applied for at the quay. A car that sits at the port waiting for paperwork accrues storage charges, and the 7-day clock for the NCTS booking is already running.
Two beliefs cause trouble here. One is that a car over six months old with more than 6,000 km on it is VAT-free; that is an intra-EU rule and does not apply to a car from Japan, which pays 23% on the customs value plus duty regardless of age. The other is that the Statement on Origin can be sorted out later; a retrospective preference claim may be possible within time limits, but it is slow and uncertain, and the duty is paid first.
The two clocks
From the day the car arrives in the State, the NCTS appointment must be booked within 7 days and the car registered within 30. Both are missed more often than they should be, usually because the arrival date was not firm or the paperwork was not ready, and penalties follow. Book the appointment the day the arrival date is confirmed; the busier centres run out of slots.
At the appointment you are assessed on the evidence you have on the day. A CO2 disclosure that has not come back means the top band; a NOx figure you meant to get means the default. The disclosure request takes time, so it belongs in the weeks the car spends at sea, not in the week it lands.
On the road
The small things arrive together in the first month. Japanese tyres often lack the E-mark the NCT requires, so a set of four goes on the list. The radio receives Japanese FM, 76 to 90 MHz, and needs a band expander or a new head unit; the navigation is in Japanese and its maps are of Japan. A rear fog lamp is not mandatory, but where one is fitted it must work. Japan-only models need some parts ordered from Japan, which is a matter of a few weeks rather than a few days.
Theft is the one to take seriously. Keyless Japanese cars, the Aqua, the Prius and Lexus models among them, have been targeted in Ireland, and many Japanese-market cars have no immobiliser to the standard insurers expect. A certified immobiliser, a steering lock and a signal-blocking pouch for the key are cheap; some insurers make the first of them a condition of cover. Electric cars add two of their own: the Japanese Type 1 charging inlet, which needs a Type 2 to Type 1 cable, and CHAdeMO rapid charging, which the newest hubs are dropping.
The things that are not problems
Japan drives on the left, so the headlights dip the same way as Irish ones and the driver sits on the correct side. The speedometer already reads in kilometres per hour. The low mileage is usually genuine once the chassis-number history confirms it, because Japan’s biennial inspection makes the odometer a public record. And the Japanese-language menus that look daunting in the photographs are, on most cars, a setting or an aftermarket head unit away from English.

Open the exampleQuestions people ask
Is the six-month, 6,000 km VAT rule real?
It is real for cars moving between EU countries, where it decides whether a car is new for VAT purposes. It does not apply to a car from Japan: import VAT at 23% is charged on the customs value plus any duty whatever the age or mileage.
Can the 41% band be corrected after registration?
Evidence produced after the assessment can be put to Revenue and a re-assessment or appeal pursued, but it is slow and you have paid the higher figure in the meantime. Getting the disclosure before the appointment is the only clean route.
What if the exporter never supplies the Statement on Origin?
Duty at 10% is charged at clearance. A retrospective claim for the preferential rate may be possible within the time limits if the document turns up later, but it is uncertain and the money is paid first. Confirm the statement in writing before you bid.
Are Japanese imports more likely to be stolen?
Keyless models with no immobiliser to the Irish standard have been targeted, and insurers know it. A certified immobiliser, a steering lock and a signal-blocking pouch remove most of the risk, and the first of them is often a condition of cover.
Which mistake is the most expensive?
On a valuable car, the 41% band from missing CO2 evidence: on a €40,000 valuation it is the difference between about €5,400 and €16,400 of VRT. On a diesel, the €4,850 NOx default. On a German-built car, the duty that was never in the budget.
