ZenMarket vs Neokyo 2026: One Taxes Your Money, One Taxes the Box

Open both fee pages and read the first line, and the contest looks over. ZenMarket ¥500. Neokyo ¥350.

Neither number is the real price.

Buy from Mercari through ZenMarket and the fee is not ¥500 but ¥800. Neokyo’s ¥350 arrives with a ¥500 packing charge every time a parcel is built. And both sites keep a larger number on a different page: one on the payment page, one on the shipping page.

Across 23 articles measuring this industry’s fee tables, this pair splits along one line: where the charge attaches. ZenMarket taxes the movement of your money. Neokyo taxes the box. Which one costs you less depends on how many items you buy, where you buy them, and how the parcel travels.

The fee table lies in both directions

Service fees only, per basket (ZenMarket’s fee page, Neokyo’s fee page):

There is not one crossing point. There are three answers. On Mercari and Yahoo! Auctions, Neokyo is cheaper from the second item. At ordinary shops, from the fourth. And at ZenMarket’s featured shops (¥300 per item), Neokyo never catches up: ¥300 per item stays below ¥350 plus a shared ¥500 at any count.

So “which is cheaper” splits three ways depending on where you shop. The fee column tells you none of this.

The shipping gap is bigger than every fee difference combined

The widest gap in the table above is ¥1,750, at five Mercari items. Shipping crosses that in one line.

The same 2kg box to the United States, quoted on each service’s official estimator (ZenMarket late July 2026, Neokyo 29 July 2026; the FedEx products differ by name):

Neokyo’s DHL is less than half of ZenMarket’s DHL, and still ¥1,411 below ZenMarket’s cheapest route of any kind. Its published window is 2 to 6 days.

ZenMarket’s card sits elsewhere. It quotes EMS with no order minimum, where Doorzo locks Japan Post routes behind an $800 order total. In our 2kg US quote, no Japan Post option appeared on Neokyo’s side at all: no EMS, no airmail, no surface. If your address cannot take a courier, that difference outweighs the price gap.

Put a basket through both, and this is what lands

Three ¥2,000 Mercari items, consolidated to 2kg, shipped to the US. The same basket we used for Doorzo vs ZenMarket.

¥2,779 apart. And ZenMarket’s side travels on ECMS at a published 5 to 13 days, Neokyo’s on DHL at a published 2 to 6. On the quotes, the cheaper one is also the faster one.

(ZenMarket’s ¥15,327 matches the figure in our Doorzo comparison to the yen. Same basket, same answer.)

One taxes your money

ZenMarket runs on deposits. You fund a balance first, then pay for goods and shipping out of it. Topping up costs 3.5%: that is the figure on the official payment page, while another official page says rates start from 1%, and nothing published says which applies when.

The 3.5% never appears in a fee column. It attaches to the whole ¥14,809 you push through the balance, goods and fees and shipping together, which is where the ¥518 above comes from. The more you spend, the more this line grows.

One honest note on currency. ZenMarket’s screens display a rate about 5% below market (¥150.00 against a ¥157.48 market rate when we measured the spread on 3 August 2026), but the actual conversion is performed by PayPal or your card issuer. So that 5% cannot be counted as ZenMarket’s take.

Neokyo bills everything in yen, and no payment surcharge appears anywhere on its fee page (absence from the table is not proof no cost exists, but the table has no such line). The exchange rate, it states, is determined by your payment agency. Currency, in other words, comes down to your card on both services. What separates them on paper is one line: the 3.5%.

The other taxes the box

Neokyo’s packing charge is ¥500 per parcel up to 2kg, then ¥150 for each further kilo. Buy one item, ship one box, and the ¥350 fee is really ¥850.

But the ¥500 does not grow with the number of items inside. Pack five items into one box and it dilutes to ¥100 each. Neokyo’s pricing is built for people who consolidate.

ZenMarket consolidates and packs for free, and holds parcels for 60 days against Neokyo’s 45. Past 60 days, an overstay charge of ¥50 per day begins.

Neither will look inside. So what happens when it arrives broken?

This is the most misread part of the comparison.

Neokyo’s fee page:

Neokyo does not inspect or authenticate the item as part of the service.

ZenMarket’s fee page:

ZenMarket service fee does not include a detailed inspection of items upon arrival at the warehouse.

Both companies state, in writing, that nobody looks inside. ZenMarket points used-goods buyers to its paid Photo Service instead.

Damage in transit is where they part ways (ZenMarket’s shipping help; Neokyo’s terms as verified in FromJapan vs Neokyo):

Reputation runs Neokyo’s way on both count and score: Trustpilot 4.6 from 10,008 reviews against ZenMarket’s 4.0 from 9,493 (checked 25 July 2026). The pattern behind ZenMarket’s score is in our full review.

Which one to choose

By item count: one item, ZenMarket (¥800 against ¥850 even on Mercari). Two or more from Mercari or Yahoo! Auctions, Neokyo. Mostly featured shops, stay with ZenMarket.

By shipping: cheapest quote and shortest published window is Neokyo’s DHL, the lowest courier rate of the four major services we have measured. If you need Japan Post (EMS or surface), only ZenMarket’s side produced those options in our quotes.

If neither profile fits, our seven-service comparison holds every number we could verify across the market.

By how the money moves: to avoid the deposit fee, Neokyo. For expensive goods that the insurance actually covers (new, shop-bought), ZenMarket’s built-in ¥5,000,000 cover counts. And for used Mercari goods, neither service stands behind the seller: one excludes them from compensation in writing, the other does not inspect at all. Open the parcel the day it lands, with a camera running. Whichever name is on the box, that part is yours.
