Buyee vs ZenMarket (2026): We Priced the Same 2kg Parcel on Both

Articles comparing Japan proxy services usually stop at the fee table. ¥500 versus ¥800, thirty free storage days versus sixty. The table fills up, and you come away thinking ZenMarket is the pricier option.

That table leaves out the largest number on your invoice. International shipping.

So we fed both official calculators the same inputs (2kg, destination United States) and the numbers that came back were an order of magnitude apart from the fee difference. Below is what we found, and where ZenMarket still wins anyway. We have no financial relationship with either company.

The 30-second difference (July 2026)

We measured the shipping, and it changed the story

Neither company publishes a fixed rate card; quotes only appear inside their browser tools. So we ran identical inputs through both official calculators (2kg, destination United States, on July 29, 2026) and recorded what came back.

Buyee is cheaper on every route, by a factor of 1.6 to 2.2. While you’re deciding whether ZenMarket’s ¥300 higher fee matters, ¥6,199 moves in the shipping column. That is the single most useful thing we found.

Two caveats. These are shipping charges only: prepaid duty applies on top with both services, and it depends on what you buy. And ZenMarket’s DHL is the “GREEN+” tier, which may not be an identical product to Buyee’s standard DHL. Compare FedEx to FedEx and ECMS to ECMS, though, and the gap holds.

Why EMS to the US is complicated right now

Buyee’s calculator returns EMS as unavailable. The reason isn’t a difference between the two companies. It sits with Japan Post.

After the US ended duty-free treatment for low-value imports in July 2025, Japan Post suspended acceptance of US-bound mail containing “goods intended for sale for consumption” and “individual gifts with a content value exceeding 100 US dollars,” effective August 27, 2025. Letters, postcards, printed matter, EMS (documents) and personal gifts under $100 still go.

Japan Post’s country availability table (checked July 29, 2026) still marks US-bound EMS with an asterisk, “acceptable for some items or to some regions.” It is a partial restriction, not a shutdown.

• Buyee has removed US-bound EMS from its options. Since proxy purchases plausibly count as goods for sale, that’s a defensible operational call
• ZenMarket’s calculator still quotes EMS at ¥7,900, but whether your particular parcel can actually go is decided by its contents, and the quote screen won’t tell you

That ¥7,900 matches Japan Post’s published EMS rate for 2kg to the US exactly, which confirms ZenMarket passes the postal rate through unchanged.

Update (July 29, 2026): we ran the same 2kg-to-US quote through two more proxies, and each handles the restriction differently again.

• Neokyo’s calculator marks US-bound EMS, airmail and surface mail as unavailable outright, no quote is returned at all
• Doorzo takes a fourth approach: Japan Post routes (EMS, EPL, airmail, surface) unlock only when the parcel’s total value exceeds US$800, which is exactly the US de minimis threshold. The practical effect is counter-intuitive: Doorzo’s cheapest option, ¥3,300 surface mail, is unavailable precisely on the small orders that would benefit most from it

Four proxies, four readings of the same postal rule. If EMS matters to you, check the quote screen of the specific service before you commit, none of them behaves the way the others do. The full breakdown of the other two, including where Doorzo’s $800 threshold leaves you, is in Doorzo vs Neokyo.

The fee difference (still worth knowing)

Watch how they count. Buyee charges per order; ZenMarket charges per item. Buy three things from one shop and Buyee can bill a single ¥500, while ZenMarket bills three items. The more you consolidate, the more Buyee’s counting method favours you.

Working the other way, ZenMarket’s ¥800 includes shipping insurance. Buying the same peace of mind on Buyee means its inspection-plus-coverage plan at ¥500 per order. That narrows the gap.

Three worked examples

Shipping is held constant at 2kg to the US via ECMS, the cheapest route on both services. Duty is excluded from both columns because it depends on the goods.

Case 1: three ¥2,000 Mercari items

Even with every protection option switched on, Buyee comes in ¥2,819 lower.

Case 2: winning one ¥5,000 Yahoo! Auctions lot

On a single item the gap is ¥3,619, essentially the shipping difference, passed straight through.

Case 3: collecting ten items over a month, shipped as one box

Buyee wins on price here too. Its weakness is the clock: miss the 30-day window and storage charges start, where ZenMarket gives you sixty free days. If your hauls take longer than a month to assemble, that matters.

Where ZenMarket still wins

Losing on shipping doesn’t settle every case.

Auction sniping works differently. Both offer last-minute automatic bidding, but ZenMarket reserves the funds from your balance the moment you place the request, and when several ZenMarket users snipe the same lot, whoever requested first takes priority. You can cancel up to 20 minutes before close. Buyee fires five minutes before close, allows cancellation until 15 minutes before, and lets you run up to 500 snipes at once. For seriously contested lots, ZenMarket’s design is the tighter one.

Support covers more languages. ZenMarket advertises 19 languages, Monday to Saturday, 9:00–18:00. Buyee offers email in 16 languages and chat in just three (Japanese, English, Chinese), with a 1–2 business day target and no weekend or holiday cover. Note though that Buyee is the only one publishing a response-time target at all; ZenMarket states opening hours only.

Its rating is climbing. ZenMarket sits at 4.1 from 9,421 reviews, up from the 4.0 we recorded on July 25. Buyee holds at 3.6 (7,899 reviews). What the reviews reward is service quality, “worth paying a bit more for” recurs constantly.

Sixty free storage days is real money for slow collectors.

FAQ

Is Buyee or ZenMarket cheaper? For US destinations, Buyee. ZenMarket’s service fee is up to ¥300 higher per item, but Buyee’s shipping ran ¥3,119–6,199 cheaper on a 2kg parcel, which flips the total. We measured this on both official calculators in July 2026.

What are the fees for each? Buyee charges ¥500 per order. ZenMarket charges per item: ¥300 at recommended stores, ¥500 at Amazon, Rakuten and most sites, and ¥800 for Mercari and Yahoo! Auctions. Note the difference between per-order and per-item billing.

Which is better for Yahoo! Auctions? ZenMarket. It reserves funds when you place a sniper bid, gives priority to whoever requested first among its own users, and allows cancellation up to 20 minutes before the auction closes.

Can I still ship to the US by EMS? It depends on the contents. After the US ended low-value duty exemptions, Japan Post stopped accepting US-bound mail containing goods for sale and gifts over $100 from August 27, 2025, and the route is still marked “some items only.” Each proxy reads that rule differently: Buyee has dropped US-bound EMS entirely; ZenMarket still quotes it, but eligibility comes down to what you bought; Neokyo marks it unavailable; and Doorzo unlocks Japan Post routes only for parcels valued over US$800.

The bottom line

“Buyee for Mercari, ZenMarket for Yahoo! Auctions” still works as a rule about where you shop. But if you live in the United States, there’s a number to check first. When moving the same 2kg box costs ¥6,199 more with one service than the other, counting ¥500 service fees is not a productive use of your attention.

Put the fee tables aside and run one quote through each calculator at the weight and method you actually use. Ours are in the table above, and for 2kg to the US, the answer came back the same every time.

Both sets of figures above assume a parcel that clears customs the usual way. That assumption changed in 2026: the US $800 duty-free threshold was suspended, so duty now applies to every parcel regardless of value. If your cart is expensive, see buying luxury goods from Japan, compensation ceilings and shipping restrictions on jewelry both come into play.
