In the past Murakami has answered readers' questions, most famously on a page opened by Asahi Shinbun called "Murakami Asahido." According to a January 6 article in Asahi Shinbun, Murakami felt that after a long break, he wanted to interact with readers again, and made a sudden decision to create the webpage, the first time he has done so in nine years. The website will be called "Murakami-san no tokoro," or, "Mr. Murakami's Place."
This is the announcement on the Shinchosha site: http://www.shinchosha.co.jp/murakamisannotokoro/
Perhaps this readers' forum will also lead to a similar publication in the future.
