On 18 May 2019, Ani-Monsanto Day, Japan, South Korean and Taiwanese citizens' organizations taking action against GMOs announced a joint statement protesting against a potato developed by Simplot using RNA interference. South Korea is very close to approving this potato and there is a possibility that Taiwan will also approve it. In Japan, the potato is already approved for distribution as human food, but as it has yet to receive approval under the Cartagena laws, it cannot yet be cultivated. There is a string possibility that the potato will be imported as fried potatoes or potato chips. Because of this, the Consumers Union of Japan and other organizations are calling on fast food chains and family restaurant chains not to use the potato.

On 7 May 2019, the Ministry of the Environment and MAFF carried out an administrative action against the Gunma Prefecture Sericultural Technology Center for using GM silkworms without performing the safety screening stipulated by the Cartagena laws. A gene from jellyfish that expresses luminescence has been inserted into these silkworms to produce silk thread that gives off a green light. The center used a silkworm line that has not yet received approval. The silkworms had already been shipped to silk-raising farmers.
