Well, there are a number of things that spring to mind:
So my favourite Japanese dishes are Okonomiyaki, which I suppose is the equivalent to an Omlete but with tons more ingredients, i.e. cabbage... Takoyaki which are the ball things above, main ingredient being Octopus YUM. Any anything that involves cooking an insane amount of meat on an open flame. Oh I'm also very fond of Shashimi (fresh uncooked fish)
"Do you like natto?"
Yes I do. Tastes like cheese.
