Along the Sumida river near Tokyo Bay lies the district of Tsukiji, home of the largest fish market in the world. The Tsukiji fish market handles over 2,000 tons of seafood daily. I've been told you have to get there around 6:30am to see the wholesale tuna auctions. I was fighting jet-lag and exhaustion from over-exuberant sightseeing, so I didn't make it there until close to 8am. As such, I missed most of the auction action, but did have fun exploring the surrounding markets.
Some of the warehouse-alley streets had tiny restaurants nestled within them. I picked a small back-alley sushi place based on the pictures of the food, the price, and the fact that it was nearly full of Japanese people who all looked happy to be there. :) Thankfully, the menus had pictures on them. I chose a sushi-assortment and added a couple of extra pieces at the end that I really liked through a series of pointing and gestures to/from the sushi chef behind the bar.
The sushi was amazing - obviously the freshest sushi I've ever had.
