Japan says it will push for a resumption of commercial whaling at a meeting of the International Whaling Commission later this year.
In February, Australian Prime Minister Kevin Rudd gave Japan until November this year to stop whaling in the Antarctic.
Despite a moratorium on commercial whaling introduced in 1986, Japan continues to hunt whales in the Southern Ocean, exploiting a loophole for lethal scientific research, the ABC reports.
Fisheries Minister Hirotaka Akamatsu says Japan will now push for a resumption of commercial whaling at the IWC meeting in June.
The IWC will meet in Florida on Wednesday to discuss a compromise that would permit the outright hunting of whales in exchange for a reduced kill.
Norway and Iceland defy the commercial whaling ban entirely.
