The Japanese version of the Huffington Post website aims to encourage reserved Japanese people to participate in online discussions and express themselves, Arianna Huffington, founder of the online media giant, said Wednesday.

Huffington was in Tokyo to oversee Tuesday's launch of Huffington Post Japan, the site's sixth international edition after Canada, France, Italy Spain and the United Kingdom.

While the U.S.-based Huffington Post sometimes does its own reporting with trained journalists, "we are also a platform that is available for our readers whether they are well-known or not to be able to express themselves," Huffington, president and editor-in-chief of the Huffington Post Media Group, said during a news conference at the Japan National Press Club.
