Speech by Japanese Prime Minister Naoto Kan

"One month has passed since an earthquake of unprecedented scale struck Japan, taking thousands of precious lives," the advert said.
"In the tsunami-devastated regions there was no food, no water, no electricity and the survivors had no communications.
"At that desperate time people from around the world rallied to our side bringing hope and inspiring courage.
"We deeply appreciate the Kizuna our friends around the world have shown and I want to thank every nation, entity and you personally from the bottom of my heart."
