I had shashimi for lunch today and the tuna is really quite different from what we get on the mainland. It appeared to be three different sources of tuna, differing in fat content. Of course the more the fat, the more the Omega III fatty acids which are good for my heart (I had double bypass in August 2000). as a matter of fact, I'll celebrate six years since surgery in Hiroshima on August 8. I did not plan this but it just happened this way.
Well you know here in the US, you almost always have a choice of Maguro (regular) or Toro (fatty) tuna.
