Nowadays the sight of people passing time on the train by sending e-mail with their mobile phones is an everyday occurrence in Japan. This technology has now led to the emergence of a new and unexpected phenomenon: people reading entire novels on their mobile phones. The growing population of readers consists mainly of young people in their late teens and early twenties, the first generation to have grown up with e-mail. One novel that achieved popularity through this new medium went on to be published in print and became a million-copy bestseller. The fact that the novel is now being made into a movie illustrates just how far this phenomenon has come.
