Do You Need Product Liability Insurance to Sell in Japan?

Most overseas brands plan their Japan launch around the things that stop a launch: the entity question, the customs question, the tax registration, the platform application. Product liability rarely makes that list, because in the home market it usually sits with the factory. Japan moves it. One clause in a 1994 statute decides who a Japanese consumer sues when a product injures them, and for imported goods the answer is almost never the factory.

The One Clause That Decides This

Japan's Product Liability Act — 製造物責任法, Act No. 85 of 1994, in force since July 1995 and last amended by the Civil Code reform package of 2017 — defines who can be sued in Article 2, paragraph 3. Item (i) is the one that matters to anyone selling across a border. It defines a manufacturer as a person who manufactured, processed or imported the product in the course of trade. Import sits in the same sentence as manufacture, with no qualifier attached.

Article 3 then attaches liability to that status: a manufacturer is liable for damage caused to another person's life, body or property by a defect in a product it delivered. What makes this different from ordinary negligence is what the injured party does not have to prove. There is no need to establish that you were careless, or that you could have caught the defect. A defect, damage and a causal link are enough. A defect, in Article 2 paragraph 2, means the product lacks the safety it ordinarily ought to have, judged against its characteristics, its ordinarily foreseeable use, and the time it was delivered.

JETRO states the reasoning behind the import rule bluntly in its own trade Q&A: an injured Japanese consumer cannot realistically pursue a manufacturer in another jurisdiction, so the law names the domestic importer as the responsible party and leaves the importer to chase the factory afterwards. That is a deliberate allocation, not an oversight. Whether you can actually chase the factory is a contract question, and we come back to it below, because most brands lose that argument before the product ever ships.

Three Ways a Foreign Brand Ends Up on the Hook

The clause catches more structures than the word "importer" suggests. Three configurations are worth checking against your own setup.

You set up a Japanese entity and import your own goods. This is the plain case. Your Japanese company is the importer of record, it is a manufacturer under Article 2(3)(i), and the exposure sits squarely with it. Brands often discover this at the point they finally establish an entity, having assumed the entity decision was about tax and platform eligibility — the topic we work through in our guide to whether you need a Japan entity to sell. Liability capture belongs in that same decision.

Your name is on the box, but someone else imports it. Article 2(3)(ii) reaches anyone who displays their name on the product as its manufacturer, or displays it in a way that misleads people into thinking they are. The chamber-of-commerce insurance programme spells out the commercial reality of this clause in its own rate documentation, describing name-display manufacturers as including sellers of OEM and private-brand products. If you commission a factory and sell the output under your own brand, the fact that a Japanese trading company handled the import does not automatically move liability away from you.

You ship cross-border and the shopper is the importer. This is the configuration most English guidance glosses over. In a direct-to-consumer cross-border model, the buyer is frequently the importer of record for their own parcel — which means there may be no Japanese business that imported the goods in the course of trade, and therefore no domestic manufacturer under the Act for the consumer to sue. Do not read that as a loophole worth engineering around. It leaves an injured Japanese customer with no straightforward domestic defendant, which is exactly the situation that produces platform escalations, consumer-centre complaints and press coverage, none of which an insurance policy fixes. It also changes the moment you appoint a Japanese importer or move stock into a Japanese warehouse. If you are weighing that shift, the boundary questions are the same ones we set out in who is responsible at the customs line.

What the Policy Covers, and Three Things It Does Not

A Japanese PL policy — 生産物賠償責任保険 — pays the damages and defence costs you become legally liable for when a product you made or sold, or work you performed, injures someone or damages property belonging to someone else. Insurers describe the covered risk in two halves: the product itself, and the result of your work. The textbook example given to regulators is a television that catches fire from a defect and burns down a house.

One feature is worth knowing because it is more generous than the statute. In the hearing Mitsui Sumitomo gave to the Consumer Affairs Agency in September 2025, the insurer noted that the standard product endorsement covers loss arising from products broadly and is not limited to defects as defined by the Product Liability Act. Your policy can respond in situations where a claim under the Act itself would fail.

Three limits matter for planning:

• Damage confined to the product itself is outside the Act. The statute covers injury to life, body or other property. If the only casualty is the defective item, that is a warranty and refund problem, not a product liability claim.
• Recall costs are a separate purchase. The expense of pulling stock, notifying customers and destroying or replacing inventory is handled by recall insurance or a recall endorsement bought alongside the PL policy, each with its own premium — on the chamber programme the enhanced recall endorsement carries a minimum premium of 30,000 yen on its own. Meanwhile the standard policy obliges you to take recall measures when an accident occurs or is anticipated, so the duty can arrive before the cover for it does.
• Deliberate breach of law is excluded. Losses from products you knowingly made or sold in violation of law are outside cover as a matter of public policy, although the same insurer confirmed that gross negligence remains covered so that victims are not left uncompensated. For regulated goods this is where compliance work and insurance meet — the cosmetics and quasi-drug rules we cover in our Yakuhin Iryokiki-ho compliance guide are not merely a market-access hurdle.

Why Your Premium Comes Back at Manufacturer Rates

Here is the part that reorders budgets. Insurers price a distributor below a manufacturer for the same product, because the risk of causing the defect sits upstream. Importers do not get that discount. Mitsui Sumitomo put it to the Consumer Affairs Agency in one sentence: importers and name-display manufacturers are treated as equivalent to manufacturing risk, not distribution risk.

The chambers of commerce publish a rate table for their SME programme that applies the same rule as an instruction: an importer or name-display manufacturer must enter a manufacturing risk code, not a distribution code. Rates are quoted per million yen of sales, against four coverage tiers — 50 million, 100 million, 200 million and 300 million yen. The edition we worked from takes effect from July 2018, so treat every figure below as an order of magnitude for planning and get a current quote before you budget:

• Cosmetics — manufacturing 1,925 yen per million yen of sales, against 115 yen for cosmetics retailing.
• Household electrical appliances that contact the body — 950 yen, against 543 yen for retailing them.
• Children's toys and play equipment — 442 yen.
• Food and beverages — 83 yen for retail; canned and bottled food manufacturing 581 yen.
• Pharmaceuticals — 3,422 yen, the top of the range and a reminder that some categories are not casually entered.

All of those are the rate at the lowest tier, 50 million yen of cover. Rates rise with the tier, so run any example at the limit you would actually buy. Take the 100 million yen tier throughout. A cosmetics brand doing 50 million yen a year in Japan is rated there at 2,562 yen per million: about 128,000 yen a year. The same brand, if it were merely a retailer of someone else's cosmetics, would be rated at 145 yen per million — about 7,250 yen. Roughly seventeen times, and the only thing that changed is who brought the goods into the country. At the same 100 million yen tier, a consumer-electronics brand selling 30 million yen of body-contact appliances is rated at 1,229 yen per million, or about 37,000 yen; a toy brand at 20 million yen is rated at 588 yen per million, about 12,000 yen.

Two conclusions follow. The first is that this is a small line item in absolute terms — six figures in yen against a launch that will spend far more on localisation and advertising. The second is that the multiplier, not the amount, is the signal: the market is telling you it prices imported-goods risk at factory level. If your Japan P&L was built on a distributor's cost assumptions, this is one of several places it will be wrong.

Can You Buy It Without a Japan Entity?

The cheapest route is closed to you. The SME programme quoted above is a group scheme available only to small and medium enterprises that belong to a Japanese chamber of commerce, a commerce and industry association or a prefectural SME federation. Membership presumes a Japanese business. That leaves three options, and they differ in who is protected rather than in price:

• Rely on your Japanese importer or distributor's policy. Costs you nothing and protects them. If their insurer pays a claim caused by your product, it may then pursue you as the upstream party — the same subrogation mechanism described below, pointed in your direction.
• Buy a Japanese commercial policy through your own Japanese entity. Available once you have incorporated, priced on the factors insurers named to the Consumer Affairs Agency: the classification and nature of the product, your sales volume, the limit and deductible you choose, and the scope of cover.
• Extend your home-market liability programme to Japan. Standard practice for exporters and the usual answer when there is no Japanese entity. Whether your existing policy already reaches Japan is a question for your broker, and the territorial wording is where these arrangements usually fail.

We are an ecommerce operations partner, not an insurance broker and not a law firm. We can tell you which structure puts the obligation where, because that is an operating-model question we deal with constantly. Selecting a policy, reading the wording and interpreting the statute belong with a licensed insurance broker and a Japanese lawyer, and we will say so rather than improvise.

Do the Platforms Require It?

This is where a lot of English content overreaches, so the boundary is worth drawing precisely. We could not verify a publicly readable clause in any of the three major Japanese marketplaces' seller terms making PL insurance a condition of opening a store.

What is verifiable is narrower and still useful. Rakuten operates an optional group product liability programme for Rakuten Ichiba merchants through its own insurance arm, structured so a single contract can cover a merchant's Rakuten shop together with its other online shops and physical stores. That is a merchant benefit, not a gate. Yahoo! Shopping's published insurance material is directed at shoppers, not at store operators. Amazon's seller agreement is behind a Seller Central login; we could not read the Japanese text without an account, and Japanese agency write-ups describing an insurance obligation triggered by a notification or a sales threshold are secondary sources. If this matters to your launch plan, read the agreement in your own account and search it for 保険. Do not plan around a summary, ours included.

The more practical trigger is commercial rather than contractual. Japanese retail partners, department-store concessions and B2B buyers routinely ask for a certificate of insurance before they will stock an imported brand, and that request tends to arrive after you have already agreed terms.

The Contract Clause That Decides Whether You Can Recover

Everything above concerns who pays the injured customer. The second question is who ultimately bears it, and that one is settled in your supply contract long before an accident.

If you carry insurance and your insurer pays a claim caused by a component or a finished product from an upstream maker, the insurer can pursue that maker for recovery — 求償 — stepping into your shoes. In the September 2025 hearing, the insurer set out the practical constraint on that mechanism: because subrogation is the exercise of your rights, an agreement between you and the upstream manufacturer that forbids recovery blocks it. Whether the insurer bothers is a commercial judgement about provability and the counterparty's ability to pay.

Translated into procurement language: a no-recourse or liability-waiver clause in your OEM agreement, the kind that arrives in a factory's standard terms and gets initialled without much thought, can quietly convert a recoverable loss into a permanent one — and it can make your own cover harder or dearer to place. JETRO makes the same point from the other direction, noting that a successful recovery against an overseas maker depends on having agreed the allocation of responsibility, in writing, before export. If you take one action away from this article, make it a read of the liability and indemnity clauses in the contract you already signed.

How to Decide, in Order

1. Establish which of the three configurations you are in. Importer of record, name-display manufacturer, or cross-border with the shopper importing. Anything else is guesswork until this is settled.
2. Price the exposure at manufacturing rates, not distribution rates. Use your category's manufacturing band and your realistic Japan revenue. If the number is trivial against your launch budget, the decision is already made.
3. Read your supply contract before you buy a policy. A recovery waiver upstream changes what the policy is worth.
4. Ask your distributor whose policy responds, and get the answer in writing. "We are covered" is not an answer; whether you are an insured party under it is.
5. Fold this into the entity decision, not after it. Cover availability, cost and who is protected all change with a Japanese entity, so it belongs beside the tax and platform-eligibility arguments rather than in a later compliance sweep.

Where we fit is deliberately narrow. We run Japanese storefronts and marketplace operations for overseas brands — the listings, the Japanese-language customer contact, the campaign calendar, the platform work. We do not act as your importer of record, we do not broker insurance and we do not give legal or tax advice; those sit with a customs broker, a licensed insurance broker and a Japanese lawyer respectively, and we will tell you when a question has crossed that line. What we will do is make sure the operating model you are about to commit to has an owner for each obligation. If you want that mapped against your own structure, tell us what you sell and how it reaches Japan. Scope and pricing are quoted against the work rather than from a rate card.
