They should take a cue from the Eskimos
Perhaps the Japanese should take a cue from the American Eskimos. They are permitted to hunt whales, but only from small boats (boats, not ships) using hand held harpoons. That would seem like a fair way of doing it.
As far as their attitude that science supports them, science supports the American view that global warming is a myth. Just ask us.
