U.S. Animal Protection asked the Tokyo Organising Committee to replace the egg supplier, saying Ise Foods "treated" the chickens "cruelly."

Kyodo News Agency reported on May 13 that the American animal protection organization Peta For Animals (PETA) submitted a letter to Toshiro Muto, secretary general of the Tokyo Olympic and Paralympic Organizing Committee, requesting adjustments to the supply of eggs by Japanese egg production giant Ise Foods to the Tokyo Olympic and Paralympic Games. PETA argues that Ise Foods is obviously "everyday cruelty" to chickens.

In addition, PETA submitted a whistle-blowing letter to the Ishioka Police Station in Ibaraki Prefecture, Japan, arguing that the way Ise Food Management Tsukuba Farms treated chickens was suspected of violating the Animal Care Act. In response, Ise Foods said that "measures have been taken to take into account the 'animal welfare' of raising livestock [in a comfortable environment]."

According to Ise Foods, in October 2018, Tsukuba Farm obtained the Japanese version of the certification "JGAP" that proves that it has thoroughly managed the production and management of agricultural products. Ise Foods considers JGAP to be "a condition for providing food standards for the Tokyo Olympic and Paralympic Games." PETA, based on a video taken by whistleblowers inside Tsukuba Farms, pointed out that a large number of chickens were concentrated in small chicken cages and kept in too dense a state, suffering from disease and injury and untreated, and were left untreated.

In response, the Tokyo 2020 Organizing Committee responded in an interview that it "hopes that the Japan GAP Association, which manages JGAP certification, will respond appropriately." The Japan GAP Association said that it "has not yet grasped the details and has no response plan."
