I'm a sucker for unagi (eel). I've always seen it cooked with a yum barbeque-type sauce. Sooo good as sushi or on rice!
Also, if you're going to a sushi bar, I also recommend going for the magoro and chutoro (forms of tuna)- they are magnificent!
Sorry, hate natto! It's a unique thing to be non-Japanese and love it, so good on you to those who do! The only other things I can't eat are sticky potato and ikura (salmon roe).
The thing I love about Japan is every area is famous for some kind of food. Where I lived in Osaka, the famous foods were takoyaki (ball of batter with a piece of octopus in it), and okonomiyaki (cross between a cabbage omelette and a pancake). Anyone like those? I found them very tasty but fattening...
