This document discusses Japanese e-books, social media, and social reading. It begins by looking at the growth of e-books in Japan and how mobile phones have become the dominant e-book reading platform. It then examines real-time sharing on social media in Japan and highlights a type of shared video content called "Dadamore." Finally, it considers potential future developments in social reading services that could allow users to share their e-book reading experiences in real time.

sharing

41. Time-shift in users of social media in
Japan

42. The trend of real time sharing
• In 2011, “twitter” overtook “mixi” in the number of
users.
– mixi is the most famous Social Networking
Service (SNS) in Japan
• mixi was released in 2004.
• Users of mixi keep diary and leave comments on their
friend’s diary.
– is a microblogging service, enabling its
users to send and read messages called tweets.
• Tweets are text-based posts of up to 140 characters.
• A lot of people share their “now” by using
social media.

world by using “Ustream” or “Nico Nico

broadcast every day.
– Academic conferences

reading service

50. Foresight of E-book reading service
• Existing reading support web service in
Japan
• These services only help users share their book reports
after reading.
• In the near future, more services are
expected to be available that also help
readers of E-books share their reading
experiences themselves.
