The Tokyo District Court has ordered Amazon Japan to pay 35 million yen in damages to a Japanese medical device seller after ruling that the company failed to take appropriate action against counterfeit products listed on its platform. Despite being notified of fake listings resembling the seller's genuine products, Amazon did not investigate the claims and instead removed the seller's legitimate listings. The court found this to be either intentional misconduct or gross negligence on Amazon's part. The ruling emphasized Amazon's obligation to implement concrete measures against counterfeit goods to protect legitimate sellers. The case highlights ongoing challenges in managing counterfeit product sales on major e-commerce platforms in Japan.
