Abstract
In Japan, e-books have been becoming popular and their market has been growing for the last years. There are two types of the reader; a special device for e-books and a software application in a general device. The former is popular for e-books reading worldwide. However, the e-reader has not generally been accepted in Japan, because there are not still enough Japanese contents for the e-reader. It is also caused by the difference of the publishing culture and attitude toward e-books between Japan and the others. In this paper, we survey the difference and Japanese e-book market and discuss a means to recognize the e-reader as a general tool of e-books reading.
