Japanese regulations for consumer brands

Your product, checked against Japanese regulations

Fourteen Japanese product rules and the trademark register, run against your actual product and its actual claims. Written in plain English, so you can act on it without a translator or a lawyer to interpret it first.

£395 fixed, five working days. Whether the stock is already on sale in Japan or still sitting in your warehouse. Full refund if every gate comes back clear. Or read a real one first.
The free check tells you whether there is a problem. The report tells you what it is, what it costs, and how to clear it.

What the report tells you

Which regulations apply

Fourteen sets of Japanese product rules, run against what you actually sell and what your packaging actually claims — not the category it looks like it belongs to.

What each one requires

The certification or labelling it forces on you, an indicative cost, a lead time, and who to take it to.

Whether your name is gone

Japan is first-to-file. The report says who holds your name on the Japanese register, if anyone does.

What to do, in what order

A verdict — go, no-go, or fix these first — with the fixes sequenced so nothing waits on something later in the list.

How this usually surfaces

Most brands find out in one of three ways.

A shipment that doesn’t clear. A listing pulled without warning. Or a name that turns out to belong to somebody else. None of the three announce themselves in advance.

類

It isn’t the product you think it is

A wooden product can be regulated as something other than a toy. A skincare product as something other than a cosmetic. A single sentence on your packaging can move the whole product under a different set of rules, each with its own certification, labelling and lead time. None of those reclassifications are guessable from the outside.

代

Some of it has nothing to do with your product

Every non-Japanese seller has needed a customs representative in Japan since October 2023. Your product can be entirely legal, correctly labelled and properly certified, and still sit at the border because of who is named on the paperwork.

名

The name may already be gone

Japan is first to file. Whoever registers your name owns it there, brand or not, and having sold under it for years elsewhere does not help you. Most brands discover this at the moment they try to use it.

What gets checked

Fourteen gates, plus the trademark position.

Every gate is run against your actual product and its actual claims, not the category it sits in.

J-PlatPat — the Japanese register

Every gate that fires comes back with what it requires, an indicative cost, a timeline, and who to take it to, in the order to do them in.

How it's checked

You can check the work.

A verdict you can't verify is just an opinion with an invoice attached. Everything here is built to be argued with.

法

Every finding names the law

Not "this may need certification". The statute, in Japanese with an English gloss, and the specific requirement it creates. Your freight forwarder, your lawyer or your Japanese distributor can check it against the same source.

原

Primary sources, not summaries

Checks run against the ministries and registers themselves, not against blog posts or a competitor's guide. Where a source was ambiguous or offline on the day, the report says so rather than guessing.

否

The negatives are shown too

The workbook has two tabs. Tab one is what you have to act on. Tab two is every check that was run, including the ones that came back clear, so you can see the scope of what was looked at, not just what happened to fire.

Sources the checks run against:

METI — Ministry of Economy, Trade and Industry MHLW — Ministry of Health, Labour and Welfare J-PlatPat — the Japanese trademark register e-Gov — the statute texts Japan Customs Consumer Affairs Agency

Compliance Flag Report

£395 · five working days · one product

Who does the work

You get the person doing the research.

I'm an Amazon market researcher by trade, with a background in data analysis and fraud detection at the DWP. Years of finding the one irregular record in a dataset of millions taught me how to spot risk before it becomes a problem, which is exactly what you need when you're launching a product on Amazon Japan.

Genkan Co. is me plus a tight network of local experts: native Japanese speakers who know the regulatory environment inside out. METI, MHLW, trademark law, Amazon's restricted categories. We map it all back to one question: what is actually standing between this product and the Japanese market?

Because there's no agency bloat behind this, you get direct access to the people doing the research. That's why it's £395 and five days, not £2,000 and a month of back-and-forth.

What I am, and what I'm not →

Once it clears

The check is the start of the job, not the whole of it.

Once a product is cleared to sell, GenkanCo does the two pieces that come next.

Listing localisation. The Japanese listing built from scratch rather than translated: title, bullets, description, structured attributes and backend search terms, as a paste-ready sheet.

Image localisation. The product image stack rebuilt for a Japanese buyer, who reads a listing in a different order and expects different things on it.

Both are quoted separately, when you want them. Every Japanese line is written to a documented rulebook and checked by a native speaker before sign-off.

Refunds and cancellation

The terms, in plain English.

Cancel before work starts

Full refund, no questions asked.

If the report comes back clear

Full refund. If nothing in it legally requires action before you can sell in Japan, you do not pay for it, and you keep the report. Recommended-not-required findings, and an ambiguous trademark position, are not a clear result.

After delivery, where it is not clear

Not refundable, because it is research work supplied in full.

If a rush deadline is missed

The rush premium is refunded.

If a primary source is down

The Japanese trademark register schedules outages. You are told the same day and the rush premium comes back, rather than the checks being compressed.

The full terms of business are here.

Scope. GenkanCo is advisory. It is not a law firm, a certification body, or a registered Japan compliance agent, and nothing it produces is legal advice or a certification opinion. It identifies where Japanese regulation is likely to apply to a product and what would need resolving, so those questions can be taken to the right specialist. Decisions about compliance, registration and importation remain yours, taken on your own professional advice. Japan today; the EU equivalent is in build.
