Mitsubishi purchases a very large percentage of the bluefin tuna catch in Japan.  Not only are they endangered, but the yearly catch is much higher than is allowed by international agreeements.  Mitsubishi could be single handedly responsible for decimating the bluefin tuna population with the hopes of profiting when they get fished into extinction.

This practice was researched and documented in the full length documentary "The End of The Line".

You state in your position:

Corporate Responsibility to Society: "Shoki Hoko"Strive to enrich society, both materially and spiritually, while contributing to the preservation of the global environment.

You cant cause the demise of  great Bluefin Tuna and be serious about protecting the environment.

Perhaps if we stop buying the many Mitsubishi products, they may realize that their customer base is much wider than the Japanese Sushi eaters.  We are also smarter than the dumb big fish that fall victim to their merciless buying practises
