We would love to do the "line up at 4:30 am and watch the auction" at the fish market. Apparently only 140 people get it and the place is hard to figure your way around unless you know Japanese.
Anyone know of a good local guide? The guides we've found online are kind of lame (they start at like 9 am, so they miss the auction, and have a sushi-making class, which we don't want).
