The only way to stop the Japanese is to kill all the whales, they are going to continue to whale because its just too much profit.
Yeah their seafood industry is ma$$ive ... this was only a few days ago ...

"A tuna has been sold at auction in Tokyo's fish market for 16.28 million yen ($175,000, £109,000), the highest price paid in Japan for nine years.
The bluefin tuna weighs 232 kg - nearly four times as much as the average Japanese man."
How's that!!! A single dead tuna ... US$175,000
So yeah you can only imagine what an endangered Fin Whale would be worth (25 metres/82 ft is about 70,000kgs/150,000 lb)- it does end up at their markets afterall
(well, at least after it's been processed on their Nisshin Maru vessel to remove all the harpoon grenade residue and dodgy exploded bits)
