martian marathon fundraising for Japan relief

I'm running a half marathon on April 2nd in Dearborn, MI, and would like to use this opportunity to raise fund for relief efforts in Japan. As you may know, I happened to be at my parents' house near Tokyo when the earthquake hit on March 11th. Luckily my parents, my sisters in Tokyo and their families are all OK, as well as my cousin in Sendai and relatives in Fukushima. But there are so many people in need of help, especially in the coastal areas where Tsunami destroyed their homes. Pls help.
