OK, I usually don't do too well with slaughtered animals. Although I do eat fish, I prefer not to think about it all sliced open and oozing its guts onto a platter. So imagine my surprise when I encountered the aesthetic pleasures of the Tsujki Fish Market! I seriously couldn't stop snapping pictures. The fish, dead though they were, were displayed so beautifully. And the people working at the fish market were, by far, the friendliest and most responsive I encountered in Tokyo. I think there's stuff to see as long as you arrive before 10AM or so. You can easily get there by train.
