If you're thinking about selling your car

Close-up of a Japanese car auction inspection sheet showing the vehicle condition diagram with defect codes in Japan and you've been quoted a number that feels surprisingly low, you're probably looking at a kaitori offer. Kaitori (買取) is the chain-buyer system — companies like Gulliver, WeCars (formerly Big Motor), Nextage, IDOM, and Apple that exist to buy cars from sellers and feed them into their own dealership networks. Their price is roughly 50 to 70 percent of what the same car lists for on CarSensor, and there's a real reason for that gap that has nothing to do with anyone trying to rip you off.

This article explains how kaitori buyers actually price cars, why the gap exists, what to do with that information, and when the gap turns into the legendary "you pay us to take it" offer.

Quick reference

What is kaitori, exactly?

Kaitori (買取) means "buy-take" in Japanese — the literal sense is "we buy it, we take it." It's the umbrella term for chain buyers whose business model is sourcing used cars from individuals and reselling them through their own dealership networks.

The major players are recognizable storefronts you've probably driven past:

When you walk into any of them with a car to sell, the workflow is the same: their staff inspects the car on-site, runs it against their internal valuation system, and gives you a verbal or written offer that you can either accept on the spot or walk away from.

If you accept, the kaitori shop handles almost all the paperwork from there. You sign the meigi-henkou (ownership transfer) documents, hand over the keys and sha-ken-sho, and walk out with a payment commitment that lands in your bank account within a few business days. You'll typically need to go to your local ward office to pick up one or two documents (a juminhyo and sometimes an inkan-shomeisho) to complete the transfer, but the kaitori shop coordinates the rest.

That convenience is the whole product. You're not paying for a higher price; you're paying for not having to manage a sale.

How do kaitori buyers actually decide their offer?

They work backward from what they'll list the car for, then subtract their costs and their margin. The math is roughly:

Their offer ≈ expected retail listing − reconditioning − marketing/lot cost − margin

Each of those subtractions is real money:

Reconditioning. Almost every used car needs work before it goes back on a lot. Detailing inside and out (¥20,000 to ¥50,000). Minor bodywork — pulling small dents, polishing scratches, touching up paint chips (¥30,000 to ¥150,000). Any mechanical work the inspection flags. Tires if they're below the threshold the chain wants on its lot.

Sha-ken. If your sha-ken is within 12 months of expiration, the next buyer will want a fresh certificate, which means the kaitori shop is running it through sha-ken before resale. That's another ¥80,000 to ¥150,000 baked into their cost.

Lot space and marketing. Every car on a kaitori lot is taking up space that could be holding a different car. It's reasonable to assume chain dealers are spending something like ¥1,000 to ¥3,000 per day in holding cost per car — exact numbers vary by chain and aren't something they publish — and a car that sits 60 days on those assumptions has consumed ¥60,000 to ¥180,000 in lot cost alone. CarSensor and Goo-net listing fees, photography, descriptions, all add up.

Margin. The kaitori shop needs to make money. The number that comes up consistently in conversations with people who've worked inside these chains is around ¥200,000 of gross margin per car — the minimum they want to clear after all the other costs. On a higher-value car they want more; on a kei they'll accept less; the floor across the chain is roughly there.

Add those up and the gap between "what the same car lists for on CarSensor" and "what the kaitori will offer you" is usually ¥300,000 to ¥500,000. That's why a Corolla that lists at ¥1,000,000 retail gets you a kaitori offer of ¥600,000 to ¥800,000. The math is consistent; the variability is mostly in what the inspector finds during their walkaround.

How do I actually estimate what my car is worth?

The fastest method, in three steps:

  1. Look up your car on CarSensor. Filter for the same model, same year (within one), same trim, similar mileage, and ideally the same region. Pull 5 to 10 active listings. Note the asking prices.
  2. Take the median, not the average. A few outliers (a really clean low-mileage one, a really tired high-mileage one) will skew the average. The median tells you what the middle of the market actually looks like.
  3. Multiply by 0.5 to 0.7. That's your kaitori range. The cleaner your car relative to the median (lower mileage, better condition, sha-ken not due imminently, no obvious damage), the closer to 0.7. The rougher it is, the closer to 0.5. Below 0.5 you're heading into the "we'll need to think about whether we want this" territory.

For a quick sanity check, run the same exercise on Goo-net. The two sites have slightly different inventory, but the medians should land within ¥50,000 to ¥100,000 of each other for any common model. If they don't, you've probably mis-filtered something.

A real example: a clean 2018 Toyota Sienta with 60,000 km, sha-ken running until late 2027, in northern Japan.

If the kaitori shop comes back with ¥600,000, they're either flagging something we didn't catch (interior smell, missing maintenance records, unfavorable color, a paint defect) or they're testing whether the seller knows the market. Asking "can you walk me through how you got to that number?" is the polite way to find out which.

What's the "you pay us to take it" offer about?

This one catches foreigners off guard. The first time it happens you wonder if you misunderstood the Japanese. You didn't.

For a car the kaitori shop genuinely doesn't want — meaning they think they'll either lose money reselling it, or they don't have a buyer pipeline for that specific model — the offer can flip negative. Common phrasing: "we can take it off your hands for ¥5,000" or "with the disposal costs we'd need ¥15,000 from you."

The cars that earn this treatment:

What's actually being charged in the negative offer is the kaitori shop's cost to do the matsu-sho (deregistration) paperwork plus the scrap-yard or auction-bottom-tier disposal cost, minus whatever residual value they can squeeze out of the parts. They're not making money — they're trying not to lose money — and if they can't see a path to either, they'll either decline the car outright or quote you the negative number.

This is the moment people usually call us. If a kaitori shop has quoted you a negative number, the right path is almost never to argue with that specific shop. The car has a destination, and the right destination is either a peer-to-peer sale (somebody wants exactly this car, you just need to find them) or Kurumagic Scrap, which handles the matsu-sho and the scrap-yard coordination for ¥20,000 and saves you from paying anyone else to take it.

Common mistakes when reading a kaitori offer

A few patterns that show up repeatedly:

Comparing the offer to retail and feeling cheated. The kaitori offer is supposed to be 30 to 50 percent below retail. That's not a ripoff; that's the business model. If you want retail price, you sell retail-style (private sale to another driver). If you want kaitori convenience, you take the kaitori discount. Picking one and then resenting the other is the foreigner-specific mistake.

Accepting the first offer without comparison. Walking into one Gulliver and accepting their first number is the most expensive convenience purchase most foreigners make at exit. Three to four kaitori chains will quote within 24 to 48 hours of each other. The spread between the highest and lowest offer is often ¥100,000 to ¥300,000 on the same car. Getting multiple offers is the entire mechanism behind Kurumagic Sell, and you can replicate it yourself if you have a few weeks and the Japanese to handle the conversations.

Assuming the inspection is final. Kaitori inspections happen in person, on-site, and the inspector returns to their shop to confirm with their manager before the offer is fully locked. Offers typically come back 24 to 48 hours after inspection, not on the spot. A "tentative" number quoted at your car can shift up or down by ¥30,000 to ¥100,000 by the time the formal offer lands.

Trying to negotiate against the wrong lever. Kaitori offers aren't really negotiable on price the way a dealer purchase might be. The lever that exists is timing — "if I commit by Friday, can you do ¥X?" sometimes works, especially at end of month or end of quarter when buyers are chasing volume targets. Demanding ¥100,000 more without giving them a reason to move usually just freezes the conversation.

Misreading the negative offer as an insult. It isn't. It's the kaitori shop being honest that they don't have a path to resell your car. The honest response is to thank them, take the information, and pursue a different sale channel — not to argue.
