To encourage first edition sales of Haruki Murakami’s latest novel, Colorless Tsukuru Tazaki and His Years of Pilgrimage, his publishers are going to include “a special sheet of stickers designed by five Japanese illustrators.” If that sounds as corny to you as it does to me, then consider the fact that the book likely does not need any real marketing strategy whatsoever: when it came out in Japan, it sold over a million copies per week.
