Actor Ken Watanabe joined Twitter earlier this month in order to spread awareness about the 2011 Tohoku earthquake.

The star's first tweet on May 11th was "Joining twitter for causes close to my heart." Since then, he's been actively thanking celebrities and athletes for showing support to victims in Japan, as well as directing them to "unite for japan", an English-language website dedicated helping Japan's relief efforts.
