This will come as no mystery to anyone living in Tokyo, but the best sushi in these parts can be found in and around Tsukiji fish market in Tokyo. And the best (reasonably priced) restaurant in that area is すざんまい Suzanmai.
I went there today. See below for what joy looks like.
Needless to say, I highly recommend it.

PS: Happy New Year folks, and may your 2013 be a healthy, prosperous and safe one!
