Sorry, this is not strictly about whales, but it regards the protection of wildlife in Japan.

Japan eyes action on threat-posing nonnative wildlife

TOKYO ? The Environment Ministry decided Thursday to enforce stronger measures on exterminating nonnative wildlife species in Japan that pose threats to the ecosystem, including the mongoose, ministry officials said.
Does this mean they are going to fall all non-native trees, unroot all un-native flowers and hunt down all animal species like imported dogs, cats, etc. ? That is what the article says. What's more, if you consider like me that humans are also animals, foreigners shall be aware that they will be exterminated for being non-native.
