Japanese Proxy Fees for Cards: What the Headline Rate Hides

You picked a proxy service by comparing three numbers — ¥300–800, ¥500, ¥350 — and then your invoice came in higher than the math said it should. Nothing went wrong. The advertised service fee is the one line on a proxy invoice that behaves exactly as promised; almost every other charge is tied to how many sellers you bought from, how much the card cost, or the simple fact that a box needs cardboard.

Japanese cards are a bad fit for the way these fee tables are built. Singles are cheap, light, and scattered across dozens of individual Mercari and Yahoo Auctions sellers. Fee structures designed around “an order” and “an item” quietly multiply against that shape. Here is what each service actually charges on top of the rate it advertises, checked against the official fee pages in August 2026.

The headline rate, and what sits underneath it

Every comparison you have read — including our own fee comparison — leads with the service fee. That number is accurate and it is stable. It is also, for a typical card order, not where the money goes.

Three different shapes: a percentage, a per-order charge, and a flat add-on. None of them appear in the number the service leads with, and each one punishes a different buying pattern.

ZenMarket: the fee that grows with the card

ZenMarket’s fee page lists five rows under “Fee Summary”. Four are familiar. The one that gets skipped is Funds Deposit Fee (from 1%), described as covering payment gateway fees like PayPal or Alipay — and marked “Always pay”, the same status as the item price itself.

A percentage behaves very differently from a flat fee once card prices get serious. The per-item service fee on Mercari is ¥800 whether the card is ¥500 or ¥500,000. The deposit fee is not.

The service fee itself is tiered, and the tier that matters for cards is the worst one: ¥300 for ZenMarket’s Recommended Stores, ¥500 for Amazon, Rakuten and most shops, and ¥800 for all Mercari items and JDirectItems Auction bids — which is precisely where Japanese singles live.

What you genuinely do not pay for is worth stating, because it is unusual: domestic bank transfer fees, initial packing and consolidation, shipping insurance for parcels under ¥5,000,000, and asking sellers questions. That last one is free at ZenMarket, which is not true everywhere — see our breakdown of what proxies will and won’t ask a seller.

Buyee: the flat fee is real, the per-order math is the trap

Buyee’s ¥500 is the cleanest headline in the category, and it is not a trick. Its FAQ and fee guide both state the flat rate holds even when a single order contains several purchases, and even when multiple purchases come from the same store.

The cost is one layer down. Buyee’s fee guide explains that packages are processed individually: “we process each order respectively, even if multiple orders are purchased through the same seller/store. Because of this, there will be separate domestic shipment fees for each order.” Domestic shipping runs ¥150–1,500 a time.

For most product categories that is a footnote. For cards it is the whole invoice. A want list of ten singles is routinely ten sellers, which is ten orders, which is ten ¥500 purchase fees and ten domestic shipping charges before a single card has left Japan.

Buyee’s guarantee plans sit on top: Standard ¥500, Insured Delivery ¥500, Inspection ¥300, and Lite at ¥0 with no compensation. Comparisons that quote “¥500” are quoting Lite-plus-nothing, which is the version with no protection at all.

Neokyo: the lowest rate, plus a box

Neokyo advertises ¥350 per item and it means it — the page confirms that buying several copies of the same item inside one Buy Request is charged once. Storage runs up to 45 days.

The add-on is packaging, and it is weight-based: ¥500 up to 2kg, then ¥500 plus ¥150 for each additional kilo. Card orders essentially never leave the first bracket. A hundred singles in toploaders is not 2kg. So for card buyers, Neokyo’s packaging fee is a flat ¥500 per parcel, not a scaling cost — treat it as a fixed surcharge on the ¥350, which makes the honest single-card figure ¥850.

Because nothing in Neokyo’s structure scales with price, it pulls away from the field exactly where ZenMarket’s percentage bites. On one expensive single the advertised gap is ¥450 (¥350 versus ¥800). Add ¥500 packaging on one side and at least 1% of a six-figure deposit on the other, and the real gap on a ¥150,000 card is closer to ¥1,450.

What none of them include

All three sell you logistics, not judgment. This is the part where card buyers lose actual money, because a misdescribed card is a total loss in a way a misdescribed t-shirt is not.

There is a second trap in ZenMarket’s cancellation terms. Cancelling a purchase after it reaches the warehouse costs ¥1,000 and only works if the seller accepts returns — and the page notes it is not applicable to items from JDirectItems Auction, Mercari or Rakuma at all. Those are the three platforms where Japanese singles actually trade. If the card arrives and the condition is not what the photos suggested, cancellation is not a lever you have.

That is what makes the ¥500 photo service at ZenMarket rational rather than an upsell: it is the only checkpoint that exists before the card is unreturnable. If you are buying used singles where condition language matters, read how Japanese condition terms are actually defined first, then decide whether ¥500 is expensive.

How to read a proxy fee page in two minutes

Ignore the headline. Find these four things instead, in this order:

None of this makes proxies a bad deal. For most cards outside Japan they remain the only route, and the fees are modest against what the same card costs abroad. But the number these services compete on is the number that matters least, and a want list spread across a dozen Mercari sellers is the single most expensive shape you can hand any of them.
