Whales were hunted to the brink of extinction until 1986, at which point a group of countries agreed to temporarily stop whaling for profit. 

It turned into an international semi-ban.

But conservationists are now worried the species might be under threat again. Many countries had continued to hunt whales for "scientific" purposes all along, including Japan.

Recently, Japan announced the resumption of commercial whaling in its waters.

But is it commercially sustainable? And why is whaling so important for Japan?
