Japan's fisheries minister Yoshimasa Hayashi gustures as he answers questions during an interview at his office in Tokyo on February 26, 2013. The minister said Tuesday his country will never stop hunting whales, despite fierce criticism from other nations and violent clashes at sea with militant conservationists.

Japan's fisheries minister said Tuesday his country will never stop hunting whales, despite fierce criticism from other nations and violent clashes at sea with militant conservationists.

"I don't think there will be any kind of an end for whaling by Japan," Agriculture, Forestry and Fisheries Minister Yoshimasa Hayashi told AFP in an exclusive interview.

Hayashi, who took the ministerial post overseeing the country's whaling programmes in December, said the criticism of the practice is "a cultural attack, a kind of prejudice against Japanese culture".

There is "a long historical tradition about whaling", he told AFP in his large central Tokyo office, over which portraits of Japan's revered Emperor and Empress gazed down.

"Japan is an island nation surrounded by the sea, so taking some good protein from the ocean is very important. For food security I think it's very important.

"We have never said everybody should eat whale, but we have a long tradition and culture of whaling.

"So why don't we at least agree to disagree? We have this culture and you don't have that culture," said the 52-year-old, who views the whaling port of Shimonoseki in Japan's southwest as home.

Unlike Norway and Iceland, which openly flout the 1986 moratorium on commercial whaling agreed through the International Commission on Whaling, Japan hunts using a loophole that allows for lethal scientific research.

A handout photo taken on February 25, 2013 shows the Sea Shepherd ship Bob Barker (R) colliding with the Japanese whaling fleet fuel tanker in icy waters off Antarctica. The anti-whaling Sea Shepherd Conservation Society has chased the Japanese fleet off Antarctica for several years in an attempt to stop the mammals being slaughtered.

But it makes no secret of the fact that the mammals ultimately end up on menus.

Hayashi, a graduate of the prestigious Kennedy School at Harvard University who first entered parliament in 1995, said Japan was tired of being lectured by nations whose own culinary cultures can seem a little off-colour.

"In some countries they eat dogs, like Korea. In Australia they eat kangaroos. We don't eat those animals, but we don't stop them from doing that because we understand that's their culture," Hayashi said in fluent English.

"Whaling has long been part of traditional Japanese culture, so I just would like to say 'please understand this is our culture'."

Australia and New Zealand in particular, voice outrage over Japan's annual expeditions in the Southern Ocean, which the International Whaling Commission considers a sanctuary for the ocean giants.

In the latest clash, on Monday, veteran anti-whaling campaigner Paul Watson said the Japanese factory ship, the Nisshin Maru, rammed the Sea Shepherd's much smaller vessel, the Bob Barker.

But on its website, Japan's Institute of Cetacean Research said several Sea Shepherd boats had slammed into the Nisshin Maru as the vessel attempted to refuel from her supply tanker.

"It was five hours of intense confrontation," Watson told AFP from on board the Sea Shepherd vessel the Steve Irwin.

"We took up our positions to block their approach to the (fuel tanker) Sun Laurel and they rammed the Bob Barker twice, causing considerable damage, and then they pushed it into the side of the Sun Laurel."

Watson said the Japanese threw stun grenades and fired a water cannon at his boat and damaged another Sea Shepherd vessel, the Sam Simon, but there were no injuries to Sea Shepherd crew.

The Institute of Cetacean Research said the Japanese vessels were "again subject to sabotage by the Sea Shepherd ships Steve Irwin, Bob Barker and Sam Simon".

"During their obstruction to refuelling operations the Sea Shepherd vessels rammed into... the Nisshin Maru and the supply tanker," it said.

"During the attack, the Nisshin Maru used her water pump as a preventive measure to make Sea Shepherd vessels refrain from further approaching, and repeatedly broadcasted a warning message to stop them."
