Hi there 2boxers.
Japan is a place dear to my heart. Right now there are many people needing food, water, everything.
If you can donate any amount to the Red Cross or any other reputable charity doing work over there, it will go a long way.
Here are some links...
British Red Cross - Japan Appeal (http://www.redcross.org.uk/Donate-Now/Make-a-single-donation/Japan-Tsunami-Appeal)
Japanese Red Cross Society - Emergency Relief (http://www.jrc.or.jp/english/relief/l4/Vcms4_00002070.html)
Save the Children - Japan Appeal (http://www.savethechildren.org.uk/)
