How to Buy from Japanese Shops That Don’t Ship Abroad

You found the thing. The exact colourway, the out-of-print artbook, the keyboard that never left Japan. You click through to checkout and the country dropdown says: Japan.

There are two ways around that wall, and they are not the same thing. A proxy buyer buys the item in their own name and then ships it to you. A forwarder just rents you a Japanese address — you buy it yourself, the shop delivers to a warehouse, and the warehouse sends it on.

Pick the forwarder when the shop will take your foreign card. Pick the proxy when it won't — which is almost always the case on Mercari and Yahoo Auctions. And budget for the international leg, because that, not the service fee, is where your money goes.

🧭 Proxy buyer or forwarder — which one do you need?

This section decides which of the two you sign up for, so you don't pay a proxy fee you didn't need.

A forwarder gives you a Japanese address and nothing else. With tenso.com, you register, get an address in Japan, and then shop normally on the Japanese site — you pay the store directly with your own card or PayPal. Their listed payment methods include Visa, Mastercard, JCB, American Express and UnionPay.

A proxy buyer does the buying. Buyee's official account purchases the Mercari item for you, the Japanese seller ships it to Buyee's warehouse, and Buyee forwards it on. You never touch the Japanese checkout at all.

So:

• If the shop's checkout accepts your card and a Japanese delivery address — use a forwarder. Fewer hands, lower fee.
• If the checkout rejects you, or the platform is Japan-residents-only — use a proxy. Buyee, ZenMarket and FromJapan all work this way.

Honestly, most people reading this need a proxy, because the items that make you search for this article are usually on Mercari or Yahoo Auctions. More on why in a moment.

💸 Where the markup actually lives

Here's the part that surprises people: the headline "service fee" is tiny. The shipping is not.

Buyee's purchase support fee is a flat ¥500 per order regardless of the item price (as of 2026-10). Tenso's handling fee starts at ¥50 for anything under 50 g and scales with weight up to ¥5,000 for parcels of 15 kg and over (as of 2026-10). Those are rounding errors next to the flight the box has to take.

Japan Post's EMS rates, from their own table (as of 2026-10), for a 2 kg parcel:

Now put a real order through both routes. Say a ¥6,000 item from a Japanese shop, boxed up at about 1.5 kg, going to the United States.

Buyee's own guide puts a typical international leg at roughly ¥3,000–6,000 or more depending on weight and method, and gives the example of a ¥3,000 item landing somewhere around ¥6,800–9,800 all in.

Look at the proportions. The fee you compared services over is ¥500. The flight is ¥7,900.

So the single biggest lever you have is consolidation. Three separate 1.6 kg parcels to the US each bill at the 2 kg band: ¥7,900 × 3 = ¥23,700. One consolidated 5 kg box: ¥15,100. That's roughly ¥8,600 saved on the same goods (rates as of 2026-10).

If you're buying more than one thing, buy it all in the same window, let it pile up in the warehouse, and ship once.

Two more lines worth knowing. EMS is the fast, fully tracked option; Japan Post also sells slower parcel post, small packets up to 2 kg, and surface mail, which cost less and take much longer. And tenso charges a ¥2,800 customs clearance commission on Japan Post shipments declared above ¥200,000 (as of 2026-10) — a real consideration if you're buying one expensive thing.

🚫 Why Mercari and Yahoo Auctions keep rejecting you

Two separate walls, and they stack.

The first is the card. Mercari's own help page is blunt about it: "Only credit cards issued in the country/region where the customer is registered can be used. Credit cards issued in other countries or regions cannot be used." Your card isn't broken. It's being refused on purpose.

The second is the seller. Yahoo Auctions and Mercari are domestic marketplaces, and individual sellers arrange shipping themselves with Japanese domestic labels. They are not set up to post a box to Melbourne, and most won't.

Mercari's answer was to partner with Buyee rather than open up directly. When you order through Buyee, an official Buyee account does the buying on Mercari, the seller ships domestically to Buyee's warehouse, and the box then goes on to one of 100-plus countries. Overseas payment methods like PayPal, Alipay and UnionPay work on the Buyee side.

One catch from that same announcement that genuinely matters: items only appear on Buyee after a certain amount of time has passed since they were listed on Mercari. Japanese buyers get first look. If you're hunting something that sells in ten minutes, a proxy will lose that race.

Something else to price in — a proxy purchase is a domestic Japanese purchase, so Japan's 10% consumption tax is baked into what you pay. You're not a tourist in that transaction, and there's no refund for you.

🗣 What buyers actually say

Buyee's iPhone app sits at 4.7 out of 5 from about 4,500 ratings (App Store, checked 2026-10), which is a healthier score than the horror stories suggest. The complaints are specific, though, and they're about money rather than the goods.

One review on the App Store says simply: "I paid $200 for shipping services and you give me the worst shipping service ever."

Another flags a fee people don't see coming: "They made me pay $16 to CANCEL my order, would've been nice if I paid for it from the start."

Read those as a warning about one thing only — commit before you order, and read the fee page of whichever service you pick, because the costs appear in stages rather than all at the first click.

📦 What your own customs will add

Short version: the days of small parcels sliding through untaxed are ending nearly everywhere. Not scary, just a line in your budget.

United States. The $800 de minimis exemption is gone. CBP's fact sheet states that from 29 August 2025, imported goods from all countries valued at or below $800 are no longer eligible for de minimis treatment and are subject to all applicable duties, taxes and fees. Postal shipments fall under IEEPA tariffs; a temporary flat per-item duty option ran until 28 February 2026, after which all postal shipments use the ad valorem method.

United Kingdom. VAT applies to everything sent from outside the UK except gifts worth £39 or less. Customs duty kicks in above £135 for non-excise goods. Alcohol and tobacco are charged at any value.

European Union. The €150 customs-duty exemption for parcels from outside the EU is being removed during 2026, and the Council has a mandate to collect an e-commerce handling fee from November 2026. Check your own country's current rules before a big order.

The practical takeaway: on a ¥30,000 order, assume customs and handling will add a meaningful slice on arrival, and don't be caught out by a courier invoice landing after the parcel does.

🧳 The move most people miss

If you're flying to Japan anyway — buy it there.

Japan's consumption tax is 10% (National Tax Agency). Tax-free shopping for short-stay visitors exists in physical stores, the goods go in your suitcase, and the international leg costs you nothing beyond your baggage allowance. A ¥7,900 EMS charge is roughly the price of a decent dinner for two in Tokyo.

My honest read: use a proxy for the things you genuinely can't carry home or can't find in a shop — auction-only items, second-hand rarities, anything from a seller who exists nowhere but Mercari. For normal retail stock, a day in Akihabara, Nakano Broadway or a Don Quijote beats any shipping calculator.

❓ Quick questions

Can I use a forwarder address on Mercari or Yahoo Auctions?
No. Those platforms also block foreign-issued cards, so the address alone doesn't solve it. You need a proxy.

Which is cheaper, proxy or forwarder?
The forwarder, slightly — you skip the per-order purchase fee. But the gap is a few hundred yen, and it only applies if the shop accepts your card in the first place.

How do I cut the shipping cost down?
Consolidate. Ship several items in one box, and consider slower Japan Post services instead of EMS if you're not in a hurry.

Will I be charged customs at home?
Most likely, yes. The US removed its $800 exemption, the UK charges VAT from the first pound, and the EU is phasing out its €150 duty exemption during 2026.

Can I get the Japanese tax back on a proxy purchase?
No. Tax-free shopping is for visitors buying in person in Japan.

📌 Before you order

• Two mechanisms: proxy buys for you, forwarder just holds a Japanese address for you
• Mercari and Yahoo Auctions need a proxy — foreign cards are refused outright
• The service fee is ¥500 or less; the international leg is ¥4,000–8,000 for a small box (as of 2026-10)
• Consolidating three parcels into one can save roughly ¥8,600 on a US shipment
• Your own customs will add duty and tax on arrival in most countries now

Next step: open Japan Post's EMS rate table, find your zone, and look up the weight band for the box you're imagining. That one number tells you whether this purchase makes sense before you create any account.
