TL;DR: If you sell, list, or refer other companies’ products in Japan, the hard part is not the storefront. It is deciding who the seller is, keeping someone else’s stock and prices honest on your pages, handing the buyer to a checkout you don’t control, and proving afterward that your site sent the sale. I built all four into Wild Food Japan, my own bilingual food site, and the same pattern fits distributors, agencies, tourism businesses, and any company selling through partners here.

Wild Food Japan is a project I founded and run, a sister site to this one. It lists Japanese wild meat, sea salt, free-range eggs, and matcha from producers, in English and Japanese, and sends every order to the producer’s own shop. I’m writing it up here because the build answers a question I hear from clients in different forms: “We want to sell our partners’ products online, but we don’t want to become a retailer.”

Decide who the seller is before you design anything

The first decision was legal and operational, not visual. Wild Food Japan is not the merchant of record. Each producer takes payment, ships, handles returns, and answers order questions. The site says so on every shop page, in both languages, because a buyer who thinks they bought from you will email you when the parcel is late.

That choice shaped everything after it. Japan’s Act on Specified Commercial Transactions (特定商取引法) sets out what a mail-order seller must show buyers, including the price and shipping cost, payment timing and method, delivery timing, return terms, and the seller’s name, address, and phone number. The Consumer Affairs Agency’s guide to mail-order rules lists the full set. If you are the seller, that page is yours to publish and keep accurate. If you are not, you need to be sure the real seller publishes it, because your customer will judge you by it either way.

So before a producer is listed, I check the business identity, the legal seller page on their own shop, the official checkout, the live product list, and the public evidence for quality claims. Every one of the 17 listed producers has a recorded link to its legal seller page, and the site’s test suite fails if one is missing. I also state the limit plainly on the site: being listed is not a tasting, an inspection, or a guarantee of any order. Saying what a check does not cover is part of the check.

Japanese small business commerce runs on many platforms

The 17 producers sell through five different shop systems. Ten use BASE, three use Shopify, two use ShopServe, one uses WooCommerce, and one uses Makeshop. That spread is normal in Japan. Producers choose their own systems for their own reasons, and they will not move to suit you.

A partner catalog therefore has to adapt to each platform rather than force one integration on everyone. On the Wild Food Japan shop, a buyer picks a product and quantity in English or Japanese, and the site adds that item to the producer’s own cart, where they confirm stock, shipping, and payment. Producers don’t share a cart, and they don’t need to change anything on their side. One matcha farm is the exception: its platform has no cart route I could confirm works reliably from outside, so its three products link to the official product page instead, and a test keeps that exception from quietly spreading.

Handoffs to systems you don’t control will break

The part clients underestimate is maintenance. A handoff into someone else’s checkout depends on behavior you don’t own, and platforms change it without telling you.

In September, the route Wild Food Japan used to send buyers into BASE shops started returning an error or an empty cart. Buyers would have reached a dead end on a producer’s site, which looks like the producer’s fault and is actually yours. I switched those products to open the producer’s own product page, then rebuilt the cart handoff on 7 October so in-stock items land in the producer’s normal checkout again. The site now has automated tests that check every rendered cart form against the contract each platform expects, so the next change shows up in a failed build rather than in a lost order.

Stock and prices need the same discipline. Every listing shows the date it was last compared with the producer’s shop. At the last full recrawl, on 11 October 2026, 100 of the 109 listed products were in stock and 9 were sold out or unpublished. Publishing that date is less impressive than pretending the catalog is live, and much more trustworthy.

Bilingual pages should answer real searches

A bilingual catalog earns traffic when each page answers something people actually search for. Kyon, a small deer that went wild on Izu Oshima, is a good example. A buyer who wants it types something like キョン肉 通販 (kyon meat by mail order) into a search box, so I built a single page for buying kyon meat online, in both languages, listing every cut from the island’s producer with its pack size, price, stock on the last check date, how ordering works, and a cooking note citing Japan’s health ministry. That page does more commercial work than a generic “Japanese game meat” landing page could.

The site also publishes a data page built from the Ministry of Agriculture, Forestry and Fisheries’ public figures on how captured wild animals become food. The source figures are stored as a small database and rendered as a fast static page, and each figure points back to the ministry slide it came from. It gives restaurants and other buyers context on supply, and gives the shop pages a source-backed neighbor that search engines can read.

Prove the referral, or nobody believes it

If you send buyers to partners, sooner or later someone asks how many sales you actually sent. Wild Food Japan answers that two ways. Every link that hands a buyer to a producer carries standard tracking tags, so the producer’s own analytics can see the visit came from wildfood.jp, while reference links and image credits stay untagged. For one island producer, the product pages also ask buyers to add a short note in the checkout’s order notes box, so the producer can confirm orders that came through the site without any new tracking code. Proof comes from the producer’s records, which is the evidence a partner will accept.

What to take from this if you sell through partners in Japan

The pattern carries well beyond food. If you run a distributor, a tour or experience booking site, an agency selling clients’ products, or a company whose sales team sends customers to dealer shops, the questions are the same:

  • Who is the legal seller, and is their required seller information complete?
  • Which platforms do your partners use, and what does a working handoff into each one look like today?
  • How do your pages show when stock and prices were last checked?
  • Which bilingual pages answer searches people in Japan and abroad actually make?
  • How will you and your partners agree on the sales you sent?

I build and maintain this kind of system for businesses in Japan. The Digital Baseline covers the website, accounts, payments, and handover; Operational Expansion adds a new sales channel or partner workflow once the foundation is in order. If you want to see the whole project first, the Wild Food Japan project file covers what it does and who it serves. For payment options on your own site, start with accepting payments for a Japan business.

If you’re planning a partner catalog, a referral shop, or a bilingual storefront and want a straight read on what to build first, book a Decision Session and bring the partner list. I’ll tell you where it will break before your customers find out.
