Don't know if this is common knowledge or not but I read in the paper today that the famously shy author has set up a temporary website to answer fans' questions. I guess virtual contact is less scary.
Anyhoo, you can submit your comments, story ideas, questions about cats, etc. until Jan. 31 & he'll spend the next 8 weeks or so responding.
FYI: the site ("Mr. Murakami's Place"or "Murakami-san no Tokoro") is in Japanese but he will accept english as well.
