US & Japanese Mobile Activity Compared

This represents a comparison of comScore's MobiLens data for the US market released September 15, 2010 and data for the Japanese market released September 22, 2010. The areas of major difference in behavior are 1) text messaging, which is a relatively recent phenomenon in Japan, where e-mail is the preferred form of mobile-to-mobile communication (54% usage); and 2) browser usage, which has been popular in Japan for over a decade and for a long time was more widely used than the online internet (it may still be). In terms of app usage, the gap is closing very quickly and I suspect we'll see parity sometime next year. One stat from the Japanese market, that's interesting (and not on this spreadsheet, because I don't have an apples to apples comparison) is mobile video consumption. Apparently 22% of Japanese mobile users watched TV and/or video on their mobile phones... which has to be substantially higher than in the US, where I believe usage is under 10% (a little help?).
