If you knew you only have a limited time you could devote yourself fully to your family while you still are able. You would also be able to adequately prepare for them a life after you have died. In summation some may think that Ignorance is Bliss, however from the few points I have mentioned above, I think you can see that you are doing nothing but cheating yourself and your loved ones by hiding from the truth. No matter how awful the truth may be. It's none of our business if Japan catches too many fish and kills too many whales.
Japan is one of our allies.
We don't need to antagonize more friends. I've never heard anything about it. We need to study the matter more, first. These abuses have been going on for years. When they over-fish, and kill many endangered whales and other mammals, they're hurting us.
