lol the sudden interest is probably cuz someone asked the qn on news_jpop recently and the rest of us remembered our own doubts about it.
I like lit a lot, so I was pretty excited when I first heard that Koyama took lit as well, but I began to have serious doubts when I heard how bad he is with Kanji. Well, Asian studies is interesting too! I hope he and NEWS put that knowledge to good use by touring Asia soon. ^^
Thanks for taking the time to explain!
