A dental clinic bought Google stars with a ¥5,000 QUO card for a five-star review
A Tokyo orthodontic clinic paid patients a ¥5,000 QUO card for posting a five-star Google review — a stealth ad the CAA ordered stopped.

What happened
From 15 May to 11 September 2024, the Smile Plus Sakurai Orthodontic Clinic in Futako-Tamagawa told patients who posted a five-star Google Maps review of the clinic, optionally with a comment, that they would receive a ¥5,000 QUO card or a ¥5,000 reduction in their treatment fee.
The reviews posted under this condition appeared as ordinary customer feedback. Nothing told readers they were the clinic's own promotional display, so the clinic's rating read as independent patient opinion rather than an advertisement.
Because a consumer could not identify the display as the business's own representation, the Consumer Affairs Agency found a violation of Article 5(3) of the Premiums and Representations Act. On 17 March 2025 it issued a corrective order under Article 7(1), requiring the practice to stop and the violation to be publicised.
Why it happened
- A five-star review bought with a gift card is not a patient's honest judgement
- Google star ratings are read as peer opinion, louder and more trusted than any billboard
- The target was orthodontics — a high-cost medical purchase where trust decides the choice
The lesson
A star rating is only worth the reader's belief that it is independent. Paying patients to post five stars with a gift card turns medical trust into advertising — and the CAA called it stealth.
Aftermath
The corrective order required Smile Square to stop offering the review-for-gift deal and to notify consumers that the reviews were a violation of the Act. The case adds another paid-Google-rating enforcement to the growing ステルスマーケティング line against clinics that bought their own reputation.
