I found this podcast called Josh in Japan, and in the first episode ("My first podcast", which is the only one I've heard so far) he talks about what he think is good food in Japan. It's a bit more in-depth than what we've heard here, and it's clearly from an American's point of view. Also, his pronounciation of Japanese words is very American If you're heading for Japan, you should definetely check it out!
