You can't ignore facts below:
1. massive killing of whales and dolphins regardless of the complaints from all other countries.
2. Japanese whaling practices will leave no whales for future generations, but Japan does not care.
3. Japanese crews are mean and violent to Green Peace activists (onboard small boats). Sooner or later, some innocent activists will be hurt or killed. Japan must not treat them as sub-humans and respect their rights to protest.
(Search youtube for videos showing the violent acts of Japanese fishing workers.)
4. Japan focuses on its own interests and benefits and has no regards of others' rights for survival. See how Japan handled the Fukushima disaster. High toxic radioactive water was/is being dumped into the seas.
Japan does not care about the environment, and of course, this selfish country may want neighbouring countries to share its own problems.
Now the east coast of Japan is highly toxic and seafood is highly contaminated.
Green Peace's recent research showed that 40% of seafood samples selected from food markets were contaminated. Some of the polluted samples were still within the safety limits of Japan, but radiation levels reported by GP in fact were far higher than normal levels.
But Japan's reports so far consistently showed a much lower rate of contamination. Thus Green Peace suspects that Japan is withholding informatiom.
When you buy Japanese foodstuff (esp. seafood), you have to be aware of the risks you are taking.
