The issue which most people oppose is neither whale hunting nor whale farming but whale extinction. Sei whales and certain subspecies of Minke whales, which are the specific species mentioned, are listed as endangered and near-threatened, respectively, on the IUCN Red List.

> From 1987 to the present, Japan has been sending a fleet consisting of a single factory ship and several catcher/spotting vessels to the Southern Ocean to catch Antarctic minkes under Article VIII of the IWC, which allows the culling of whales for scientific research. The first research program, Japanese Research Program in the Antarctic (JARPA), began in 1987-88, when 273 Antarctic minkes were caught. The quota and catch soon increased to 330 and 440. In 2005-06, the second research program, JARPA II, began. In its first two years, in what Japan called its "feasibility study", 850 Antarctic minkes, as well as 10 fin whales, were to be taken each season (2005–06 and 2006–07). The quota was reached in the first season, but due to a fire, only 508 Antarctic minkes were caught in the second. In 2007-08, because of constant harassment from environmental groups, they failed to reach the quota again, with a catch of only 551 whales.
