I know this is kind of late but in case you folks didn't know, Japan is still trying to recover from the aftereffects of the calamity which struck it few days back. In these horrid times, every bit of sentiment and help counts. No help given with good intentions is a 'small' help.
In case you can want to lend a helping hand by contributing financially to the relief efforts (which I think everyone should) but are unaware of a tried and tested channel which is not part of the 'sick scam' which some people are trying to pull, I would highly recommend the Google crisis response page.
The donations made from here are safe, trusted and go directly to the Japanese Red Cross. Please don't shy away from donating just because you think you aren't donating much, a small donation is better than no donation.
Remember, 'today you, tomorrow me'. Thank you.
