Japanese Product Reviews: Sponsored Content, Editorial Coverage & Product Seeding

Short answer: Japanese product reviews come in three kinds. Editorial coverage is decided and written by the media, and you can't buy it. Sponsored content is paid for, so you shape it, but it must be labeled as advertising. Product seeding means sending samples with no payment for coverage; whether a post that follows counts as advertising depends on what you asked for. Since 1 October 2023, undisclosed advertising has been illegal stealth marketing in Japan, and the advertiser, not the creator, is held responsible.

Three kinds of review, compared

Editorial coverage

Editorial articles and reviews are the outlet's own decision: whether to cover the product, how to test it and what to conclude. The Consumer Affairs Agency's operating guidelines say that content media companies plan, edit and produce of their own will is normally not the advertiser's representation. That covers articles based on normal reporting, book reviews and broadcast programs, including programs made with a company's cooperation (operating guidelines, March 2023, in Japanese).

The guidelines add a limit. If a business provides money well beyond normal reporting cooperation, or unusually large thank-you payments, the content can become the advertiser's own representation and must be labeled. In practice, earned coverage stays earned only if you don't pay the outlet for it.

What you can provide is what makes coverage possible: a clear Japanese story, accurate materials, review units and access to someone who can answer questions. See how to get Japanese media to cover your product.

Sponsored content

Japanese gadget sites sell tie-up articles (タイアップ記事), and creators sell sponsored videos and posts. You agree the topic and key messages, and usually check facts before publication. That is legitimate advertising, provided readers can see that it is advertising.

What a clear label looks like. The Consumer Affairs Agency gives 「広告」, 「宣伝」, 「プロモーション」 and 「PR」, or a sentence such as "I received this product from Company A", as examples of clear wording. It also says the list isn't exhaustive: what matters is that the whole presentation makes clear it is the business's advertisement (stealth marketing Q&A, in Japanese). For video, it notes that a label shown only at the start may be missed by viewers who join part-way. It suggests keeping the disclosure visible throughout, for example with 「広告」 on screen.

Industry rules are stricter in places. The WOM Marketing Association Japan (WOMJ) allows only #プロモーション, #PR, #宣伝 and #広告 as relationship tags, in its guideline effective from 1 October 2023 (WOMJ, June 2023, in Japanese). On YouTube, creators must also tick the paid-promotion box, which adds a disclosure at the start of the video (YouTube Help).

Product seeding

Seeding means sending products to media or creators who may review them, with no payment and no obligation to post. It is a common way for outlets and creators to get hands-on time before a launch.

The legal question is whether a post that follows is really the recipient's own opinion. If you send a product with a request to post, or say what to write, the post can become your advertisement and must be labeled. If you send a product with no conditions and the recipient decides freely, an honest review is generally their own content. Many outlets also state their policy on review units. For example, the Japanese Apple and gadget blog gori.me says it notes in the article when a product was provided or lent by a maker, and puts PR, AD or Sponsored in the title of paid articles (gori.me editorial policy, in Japanese).

Practical rules for seeding:

• Say clearly whether units are loans or gifts, and when loans come back.
• Don't ask for a positive review, a deadline or specific wording unless you are prepared to treat the result as advertising and label it.
• Choose recipients who regularly cover your category, rather than sending widely.
• Expect no response from some. Samples don't guarantee coverage.

What enforcement has looked like

The first stealth marketing order, as reported, was announced on 7 June 2024 (issued the day before) against a medical corporation that offered discounts in exchange for Google Maps reviews (Consumer Affairs Agency, in Japanese). In November 2024 the agency ordered Taisho Pharmaceutical over posts by Instagram influencers it had commissioned, which the company then reused on its own site without saying they were advertising (Consumer Affairs Agency, in Japanese). In both cases the business was the party ordered to act.

How to combine them in a launch

Most gadget launches use all three, in order:

1. Seed first to the outlets and creators most likely to care, with Japanese materials, so they can test the product.
2. Earn editorial coverage through individual outreach around the launch date.
3. Add sponsored content where you need reach that earned media didn't deliver, clearly labeled, and timed for when people can buy.

Keep them separate in reporting. A report that mixes paid and independent reviews will mislead your own decisions. See how to measure product PR ROI in Japan, and for choosing between gadget media and YouTube, Japanese gadget media vs YouTube reviews.

Where Gloture fits

In our projects, review units go to outlets without posting conditions. When content is paid, disclosure is written into the terms and checked before it goes live. Modern-G, our own media, also sells placements, which are labeled. We don't buy editorial coverage. Product PR in Japan starts from US$2,500. We don't guarantee reviews or results. To plan reviews for your launch, start a Japan PR Review.

Frequently asked questions

Can we pay a Japanese outlet for a review?

You can pay for a sponsored article or video, which is advertising and must be clearly labeled. You can't pay for independent editorial coverage. Paying an outlet well beyond normal reporting cooperation can turn the coverage into your own advertisement.

Does sending a free sample make a review an ad?

Not automatically. If you send a sample with no conditions and the recipient freely decides what to write, an honest review is generally their own content. If you ask for a post, a deadline or certain wording, treat it as advertising and make sure it is labeled.

Who gets penalized for unlabeled sponsored posts in Japan?

Under the stealth marketing rules in force since 1 October 2023, the business that advertises is responsible, not the creator. Write disclosure into contracts and check it before publication.

Is #ad enough as a label in Japan?

It is safer to use Japanese labels. The Consumer Affairs Agency cites 広告, 宣伝, プロモーション and PR as clear examples, and WOMJ's guideline allows only #プロモーション, #PR, #宣伝 and #広告 as relationship tags; it doesn't recommend #AD, #pr or #Promotion.
