Anonymous is calling for a collective protest against the Japanese tradition of whale and dolphin hunting. The group is threatening to attack 22 Japanese websites, including those of the Ministry of Agriculture, Forestry and Fisheries.
There is also a day of action planned on December 1. Activists are using #OpKillingBay and #ShutTaijiDown to demand an end to the practice in the whaling town of Taiji, which was made infamous by the Oscar-winning documentary "The Cove".
