Twitter's little blue bird has landed in Japan and looks like it might stick around to build a nest: The microblogging site had almost 10 million views in April from Japan. Ninety-five percent of people polled in a recent survey said they knew about Twitter. Granted, goo Research and japan.internet.com surveyed 1,077 people who were already online, so we'd expect higher recognition than if they polled people on the street. But still, a huge increase from 12% in a similar survey taken at the same time last year. The tweet designated as the 15 billionth this past weekend was in Japanese. For the final nudge, Twitter will come pre-installed on 13 of SoftBank's new phones this summer, and a free Twitter app for NTT DoCoMo's keitai has just been announced.

From a marketer's point of view, that's a lot of potential consumers. How to grab their attention and keep it? The first wave of Japanese corporate Twitter accounts to play with the medium mostly chatted a bit aimlessly and offered Twitter-only discounts. Many of the accounts replied automatically to messages about the company's product or shop that were posted in the common format "I'm at FamilyMart/eating udon/drinking coffee now."
