Went for spring break once with my Dad and Uncle. Very cool place to visit. We went to about 5 different ramen shops (much better than the packaged stuff), the Ghibli museum, Shinto Shrines, Buddhist Temples, saw the Emperor's Palace (not inside of course), Mt. Fuji, and a bunch of other cool places.
It's a pretty nice country to visit, that's for sure. Funny part is, although I was 2 years into my high school Japanese class at the time, I didn't speak a single word of it when I was there. I choose not to mention that to my Japanese teacher. >.>
I wouldn't call it "AWESOME" though. It's a country, like any other. It has benefits, as well as problems.
