Honestly speaking, I haven't tried a lot of Japanese food before. I've been to a few Japanese restaurants, and I really like the food, but I just can't bring myself to eat what I think is fish eggs. *turns green* Just watching my dad eat it gives me the chills.
Sushi is what I'd recommend - but there are many different types of sushi, and I haven't tried them all yet. I really like the salmon and avacado ones though. ^_^
There are a number of Japanese dishes served with rice, but I've only tried a few of them. I can't even remember the names of them, but they were meat, so I guess you wouldn't be interested lol. There are also a lot of different types of noodles, but I've never tried any of them before lol. XD
Actually, now that I think about it, the Japanese have a wide variety of foods. It's best if someone who lives in Japan gave us their opinion lol.
