“After the events in March, people relied on a variety of media sources for the latest information and developments,” said Daizo Nishitani, comScore vice president for Japan. “TV, fixed Internet, radio and mobile phones were all critical communication channels across the country in the days and weeks following the events. The media sources that were most important and useful during this time were heavily influenced by both people’s age and regional location, underscoring the fragmented nature of media consumption in Japan.”
When asked how important various information sources were for obtaining updates after the earthquake and tsunami, 83 percent of people ranked television as very important, while 72 percent cited Internet access through a personal computer. Radio broadcasts were very important for 66 percent of people, while 49 percent specified the use of mobile phones..
The importance of media sources varied considerably across age segments. Compared to older consumers, younger users found PC Internet and mobile devices more important as information sources after the disaster. Approximately 78 percent of people age 35-44 cited the fixed Internet as very important, accounting for the largest percentage of users ranking this medium as very important. Mobile phones were ranked as very important by more than half of users age 13-34, demonstrating the importance of this medium among younger consumers.
In contrast, television and radio broadcasts were more important sources of information for users in older age segments. Within 55-64 year olds, 90 percent ranked TV as very important, as did 91 percent of those 65 and older. Radio was ranked as very important by 75 percent of people age 55-64 and 78 percent of people age 65 and older.

Of those that utilized their mobile devices, 72 percent used their mobile browser, 26 percent watched television or video on their mobile, 24 percent received text or email alerts, while 6 percent used a mobile application.
