Gao Guang's Nobilun ads were paid SNS posts disguised as word of mouth
Japan ordered Gao Guang to stop disguised ads for its Nobilun children's supplements — paid SNS posts recycled onto its own sites without disclosure.

What happened
Gao Guang sold its growing-children nutrition supplements 'ノビルン' and 'ノビルンC' through its own sites and e-commerce listings. To promote them it recruited third parties, gave them the products free, and asked them to post on social media.
The company then took the photo portions of those posts and re-published them on its own sales sites — including its self-operated site, Rakuten and Yahoo! Shopping — under headlines such as 'ＳＮＳでも大人気！' (huge on SNS!) with an imitation of an Instagram icon. Nothing disclosed that the posts were commissioned advertising: consumers were left to read them as unsolicited word of mouth.
On 29 June 2026 the Consumer Affairs Agency and the Fair Trade Commission's Kinki-Chūgoku-Shikoku Office issued an administrative order under the Act Against Unjustifiable Premiums and Misleading Representations, finding a stealth-marketing violation (Article 5(3)) for presenting commissioned posts as unaffiliated independent endorsements.
Why it happened
- Paying people to post and presenting the results as independent praise
- Lifting the photos onto own-sales pages so the commercial source was hidden
- Recycling the same disguised endorsement across Rakuten and Yahoo! Shopping
The lesson
When a company pays for a post, the post is an ad, and an ad must look like an ad. Placing paid endorsements on your own sales pages without disclosure is stealth marketing, not word of mouth.
Aftermath
The CAA and regional JFTC office ordered Gao Guang to stop the undisclosed displays, notify consumers and put recurrence-prevention measures in place. The order signals Japanese regulators scrutinising supplement brands that turn recruited SNS placements into on-site social proof without ever saying the posts were commissioned.
