Twitter's march through Japan's business landscape continues as PR News launches Social Release, a service that uses Twitter streams and Facebook pages to distribute press releases.

While companies pay to have their press releases pushed out onto the service, Twitter users spread the word for free by signing up for a separate service called Social Post. By doing so, these users allow PR News to distribute press release links via their Twitter streams. Users can choose the genres they'll shill for and the ratio of their tweets that they will allow to be PR. The default setting is to send out ads for all topics, frequently.  The tweets come up with "[Social Post]" tagged at the beginning or end, lest followers wonder why you've suddenly started speaking PR-ese and spouting random links.

The service is included in the price of putting out a conventional release on PR News, or, as a separate package,  starts at ¥38,000 for a single blast. Monthly rates are around ¥70,000.
