A few days later and I still can't get my head around the scale of damage following the earthquake that hit the east coast of Japan last week. I lived in Tokyo for two years and found it to be one of the most fascinating and invigorating cities I've ever been to.
It's awful to see people in this wonderful country suffer in this way, so today's charity is the Red Cross.
The earthquake, measuring 9.0 on the Richter scale, triggered a tsunami which hit the east coast of Japan with 7-metre-high waves, leaving a trail of destruction.
More than 2,000 people have died in the disaster and some 2,000 are injured. The number of confirmed dead is expected to rise to around 10,000. The earthquake triggered fires and caused severe damage to buildings, leaving 1.2 million homes without electricity and 1.4 million without water.
The Japanese Red Cross has been working on the ground since the disaster began, mobilising 85 teams, made up of more than 700 doctors, nurses and support staff, to provide first aid and healthcare and assess the damage and needs of the communities affected.
More than 500,000 people have been evacuated and are being housed in temporary centres set up in schools and public buildings where the Red Cross is distributing thousands of blankets.
