Yes, to cheer kids (And indirectly us fans) up in the wake of the disaster in Japan, actors from various tokusatsu shows have teamed up to tweet (in character!) on the situation in Japan and to overall make everyone feel better. Because as Kane pointed out in an earlier post of mine, we need to smile, even during sad times. 
Here are some of the tweets I liked. 
“Children, please endure these tough times just a little bit longer.  Please, keep it up. Just remember that us heroes will always be by your  side. – Kotaro Minami”
“Everyone, please cheer up! Even though times are tough now, the day  where we can all be happy again will come. The day the world can sparkle  will definitely come*! My brother and I will do our best to fight for  you all! – Go-on Silver”
“I’m Jan! Everyone work hard! If you are in sad sad, the people around  you will also be sad sad but if you are help help, others will help help  too!! Cheer up! Combine your power and do good! – Gekired Jan Kandou”
“Good morning. Today is Thursday, March 17th. Everyone is rooting for  you. Everyone is protecting you. “Never give up”! That means to hang in  there. I’ll be back, so keep at it. GaoBlack.”
