Tokyo is continuing to push for the resumption of commercial whaling after their defeated proposal at the International Whaling Commision in Brazil at the start of the month.

A fisheries negotiator says if Japan doesn’t achieve sustainable use of marine life, including whales, the country will encounter serious difficulties in food security.

After a ban was imposed for commercial whaling in the 1980s due to dwindling stocks, Japan has conducted research and says that whale stocks have now recovered.
