In discussions on Japanese whaling, a common question is why Japan appears indifferent to international pressure (gaiatsu) on the issue, that is, why it continues to flout the international anti-whaling “norm” despite widespread criticism and condemnation. The key to answering this question is to examine why the anti-whaling “norm” resonates so poorly in the domestic sphere. This paper argues that the impotence of international pressure to curb Japanese whaling can only be understood by examining how whaling has come to be reactively defined in the domestic debate not as an issue of conservation and environmental protection but as a symbol of national identity and pride. The paper concludes that because whaling is framed as a key marker of “Japanese-ness”, international pressure is counter-productive as it merely serves to stoke the fires of nationalism, creating an atmosphere in which anti-whaling opinion is seen as “anti-Japanese”.
