Japan's Diet has approved a revised law in support of sustainable whaling. Japan resumed commercial hunts in July for the first time in 31 years after leaving the International Whaling Commission.
The law says the government will assist the industry by helping to secure ships and crew.
Whale meat was once a common feature of Japanese school lunches. The government will start promoting the meat to schools again in an effort to pass the culture on to future generations.
The law requires that Japan will hunt whales within quotas that are set according to scientific evidence. It also obliges the government to take measures to prevent commercial trading of illegally hunted whales.
