I’ve read a few recent news stories stating rather high user levels for Twitter in Japan that I did find quite difficult to believe, but here is a report from japan.internet.com on a survey by Point On Research into Twitter usage that backs up the data, although note that this survey is of mobile phone users with unlimited data plans.
On the 22nd of June 2010 800 heavy users of mobile phones completed a mobile phone-based questionnaire. The sample was 50:50 male and female, 25.0% in their teens, 25.0% in their twenties, 25.0% in their thirties, and 25.0% in their forties.
Note that the figures given here for usage patterns are comparable with a US-based analysis of Twitter data from last year.
As I hope you have noticed on my sidebar I’m on Twitter. I’ve tried using it from my mobile phone, but it costs me a little over 100 yen just to load a single page! I do one auto-post per day through my blog, then an occasional manual tweet. I think that as I’m an irregular tweeter replies too are rather irregular.
Finally, at least one candidate in the upcoming election is using Twitter (or should that be Barker?):
