I'd have to second the Daiwa Sushi in the Tsukiji fish market. It's not as glitzy as some of the Ginza place, but it's awesome and awesomely fresh. The fish is litterally hours off the boat. It's small, and there can be a wait, and the selection is goes only as far as whats off the boats that morning, but thats what made it so great. They dont even have plates, the food is put down right on the counter in front of you. I had some of the best toro (o-toro, actually) and yellow tail (hamachi) of my life. The amaebi (sweet shrimp) was great too, followed up by the head of the shrimp toasted crispy for you. Cire
