美英兩國人士組成的非營利環保組織「環境調查協會」（Environmental Investigation Agency）及「國際人道協會」（Humane Society International）先前發起全球反鯨肉運動，旋即形成一股極大浪潮後，亞馬遜在24小時內全面下架包括鯨魚、海豚類這些產品。
環境調查協會先前出版一份名為〈Amazon.com's Unpalatable Profits〉的報告，對日本亞馬遜網造成輿論壓力。報告中指出，日本亞馬遜這家由總公司獨資運作的子公司，無視母公司禁止販賣未核可或非法野生動物產品（包括瀕危物種）的規定，私自販賣鯨肉類產品。
2011年12月間，環境調查協會在日本亞馬遜網站上調查發現有147種鯨肉產品，且到21日為止，這些產品的連結可正常點選，但在22日，這些產品網址的網頁出現「404 File Not Found」（連結不存在）的訊息。
The Internet retail giant Amazon.com has responded to a public outcry against whale meat sales on its Japanese website by removing more than 145 food products from the site overnight.
The products made from the meat of whales, dolphins and porpoises were removed within 24 hours after a campaign launched yesterday by the Environmental Investigation Agency and Humane Society International quickly gathered worldwide momentum.

Tens of thousands of people took action via Twitter, Facebook and HSI's online petition and thousands more sent protest emails to Jeff Bezos, founder and CEO of the Seattle-based business.
"We welcome Amazon's action to remove whale products from its Japanese website but urge Amazon to confirm it will enact a company-wide ban on the sale of all products derived from whales, dolphins or porpoises," said Allan Thornton, president of the Environmental Investigation Agency, a nonprofit organization based both in the UK and the United States.
"Amazon.com's Unpalatable Profits," the EIA report that created the backlash against Amazon Japan, reveals that the wholly owned subsidiary of Amazon Inc., sold cetacean food products despite Amazon's stated policy of prohibiting the sale of unlicensed or illegal wildlife products, including endangered species.
In December 2011, EIA investigators identified 147 whale products for sale on Amazon Japan. Links to these products were active on the Amazon Japan site yesterday. But today the same links return a "404 File Not Found" message.
The listed products included fin, sei, minke and Bryde's whales, all protected by the International Whaling Commission's moratorium on commercial whaling and the Convention on International Trade in Endangered Species, which forbids international trade in body parts of endangered fin and sei whales.

In 2011, EIA investigators purchased whale products from Amazon Japan, including canned whale meat, whale jerky, whale and whale stew, some from these endangered species. Many of the products were found to be contaminated with toxic mercury at levels far higher than Japan's allowable limit.
Amazon Japan profited from the sales of whale meat. Selling contracts on Amazon Japan require third-party sellers to pay a 10 percent commission for food and drink products, including whale products, on top of a 4900 yen ($57) monthly fee, according to the EIA report.
