I'll be going to Japan with my husband toward the end of May for 2 weeks. Although we are both adventurous eaters and I am an accomplished cook, I feel utterly overwhelmed by Japanese food. Of course we've eaten our share of sushi and tempura, but I realize that really don't understand Japanese food enough and want to at least have some idea of how to experience it. We'll be staying in Tokyo for about a week, then Osaka (Kyoto and I'm not sure where else yet) for another week. Mostly we'll be with friends or family, so we'll be looked after somewhat. But there will be times when we'll be wandering solo and I'd like to have some kind of quest. Please tell me what to eat and what to look for on my travels.
