Joji Morishita has one of the more unenviable jobs on the global conference circuit: explaining why Japan wants to kill a thousand of the world's most-beloved mammals every year.
At the acrimonious annual meetings of the International Whaling Commission, Mr Morishita spends hours trying to convince western reporters that Japan is not the Darth Vader of the marine world.
'It is not true that we want free, uncontrolled whaling,' Japan's alternate IWC commissioner said in flawless English at this year's conference in Anchorage, Alaska. 'We would like to have managed, controlled whaling, with quotas and enforcement.'
The task of selling the controversial whaling programme, which sends a fleet to the Antarctic every year to hunt whales in the name of science, is about to become even more difficult. Japan plans to add a cull of 50 humpbacks, on top of its quota of minke, sei, Bryde's, sperm and fin whales.
That hunt, due to start later this year, has enraged conservationists, particularly Australia and New Zealand, which call it 'deeply provocative'.
'This is a development that will really adversely affect the image of Japan in our countries,' New Zealand Environment Minister Chris Carter warned this week.
