See former GaijinPot contributor Joseph Tame (@tamegoeswild) shatter boundaries this Sunday with his extraordinary invention – the iRun – a portable social media studio that the marathon runner will be using to share every painful step during this Sunday’s Tokyo marathon. Find out about it below and then follow him during the race, either through Twitter or a livestreamed video broadcast.

The iRun invention Joseph is using features an array of iPhone’s, an iPad, three pocket wifi units, an Android handset, and a bird-feeding dish configured to connect to multiple mobile phone networks. On top of live streaming video, the iRun has built-in support for Twitter, Runkeeper (live GPS tracking and heart-rate info), FaceTime & Skype, in addition to a mini-weather station which streams data for temperature, CO2, noise and humidity levels.

Joseph Tame, who works as a media producer during the day, is one of the best known foreign tweeters in Japan. Combining the Tokyo marathon with the iRun device follows on from last year in which he ran the 2010 Tokyo marathon uStreaming through an iPhone strapped somewhat precariously to his head.

By the end of that race, he had 13,000 people tuning in and ever since then, the buzz has continued to grow. Apart from Japanese TV Joseph has also been featured in a number of print publications both inside and out the country as well as blogs and tech sites.
