Japan will resume commercial whaling from July in its waters and exclusive economic zone while ending its controversial hunts in the Antarctic, it said on Wednesday, as it announced its withdrawal from the International Whaling Commission (IWC).

Australia and New Zealand welcomed the decision to abandon the Antarctic whale hunt, but expressed disappointment that Japan would engage in any killing of the ocean mammals.

The decision, some experts said, allows Japan to save the money it spends to support Antarctic whaling while taking a tough pro-whaling stance — a matter of national pride for some conservatives.

But doubts exist about whether Japanese commercial whaling can be economically viable, especially as fewer people than ever are eating whale meat, they said.

“From July 2019, after the withdrawal comes into effect on June 30, Japan will conduct commercial whaling within Japan’s territorial sea and its exclusive economic zone, and will cease the take of whales in the Antarctic Ocean/the Southern Hemisphere,” chief cabinet secretary Yoshihide Suga said in a statement announcing the decision.

“The whaling will be conducted in accordance with international law and within the catch limits calculated in accordance with the method adopted by the IWC to avoid negative impact on cetacean resources,” Suga said.

Japan, which says most whale species are not endangered and that eating whale is part of its culture, has long campaigned without success for the IWC to allow commercial whaling.

Some influential lawmakers’ constituencies include whaling communities, and Prime Minister Shinzo Abe’s election district is home to the whaling port of Shimonoseki.

The decision to withdraw from the IWC followed its latest rejection of Japan’s bid to resume commercial whaling at a September meeting, which Suga said showed it was impossible to bridge the gap between whaling advocates and anti-whaling members.

The resumption of commercial whaling is an unusual decision for Japan, which stresses multilateralism in its diplomacy, and it sparked swift criticism from environmental groups and others who believe all whales should be protected.

“The declaration today is out of step with the international community, let alone the protection needed to safeguard the future of our oceans and these majestic creatures,” international conservationist group Greenpeace said. “The Japanese government needs to recommit to the IWC and prioritise new measures for marine conservation.”

Yoshie Nakatani, an official at the foreign ministry’s fisheries division, said Japan would still attend IWC meetings. “It’s not like we are turning our back on the IWC and abandoning international cooperation,” she said. “There is no change to our country’s respect for the rule of law and multilateralism.”

Japan has long defied such protests to conduct what it calls scientific research whaling, having repeatedly said its ultimate goal was to whale commercially again.

Much of the meat ends up in shops, even though most Japanese no longer eat it. Whale consumption accounted for 0.1 per cent of all Japanese meat consumption, according to the Asahi newspaper.
