Here is some contact info for how you can help the people of Japan and others effected by the devastating earthquakes and tsunamis today:
Red Cross – www.redcross.org
Center for International Disaster Information – www.cidi.org
Direct Relief International – www.directrelief.org
And below is a scattershot list I found at www.appleseeds.com. Sorry for the formatting, but I thought it was more better to just get the list out there, so I’m not really concerned so much about it being pretty.
Contact the US State Department 1-888-407-4747 or 202-647-5225 for inquiries on US citizens living/traveling in Japan.
