Tokyo- In Japan, 53.6 million people were using a mobile device to access the Internet, a fraction lower than the 53.7 million who accessed the Internet from either a home or a work computer in June 2007. That’s according to a new report by comScore, which studied 3,100 people aged 15 and over. It found checking email is the most common Internet activity from mobile phones, used by 75%, while 41% checked email at least once a day. Accessing news and information was the next most popular with 52% doing so, with search and navigation queries close behind at 51%.　 Time spent web browsing on mobile phones is still much lower than that spent on desktop PCs. Internet usage on mobile phones averages 8.1 hours per month versus 18.9 hours by PC. Subscribers to the KDDI Au/TU-KA and Willcom networks spent more time surfing than NTT DoCoMo and Softbank customers.　 Despite these healthy usage figures, consumer satisfaction remains low. Only 12.6% of respondents accessing the Internet via a mobile device stated they were either “very satisfied” or “somewhat satisfied”, with 52.1% claiming they were either “very dissatisfied” or “somewhat dissatisfied.”
