I love the history. I have always despised history in school but when I first started getting into manga and anime my interest was peeked and I went to the library and cheeked out a lot of books on Japanese history. I also like to read about Japanese culture, how it is so different then mine. From vending machines to showering, it is so interesting.
Other then that, I have found myself recently watching some J drama's and actually enjoying them...its a guilty pleasure.
All in all I find Japan really interesting.
