I'm currently traveling in Japan, and since I've subjected you to seven Armchair Field Trips in the last two weeks, I think instead I'll let you see for yourselves what I've been seeing, via pictures (mine) and links (from elsewhere).

We've already talked about wasabi and namako-kabe; now let's check out the ginormous early-morning Tsukiji Fish Market in Tokyo, the biggest fish and seafood wholesaler in the world. Unfortunately, I haven't had time to transfer my pictures yet, so here are other people's:

A few links that will give you more of the flavor (pun intended):

And here's a restaurant in the market where I had a delicious fishy breakfast this morning!
