It's been more than twelve years since the International Whaling Commission banned commercial whaling. The ban has allowed some species of whales - once near the brink of extinction - to recover.

Japanese officials will make their case at an international conference in Nairobi in April, because, they say, the whaling ban is eroding a way of life. From Abashiri Japan, NPR's Eric Weiner reports.
