On a more personal note, I have read some comments on Twitter and Facebook about how Japan isn't asking for help, and/or doesn't need help.
I toured Japan with a music group in the mid 90s, and we were treated with incredible generosity and kindness. I was given armloads of flowers, and served meals more extravagant than an average Japanese person might ever be served in his lifetime. I was moved and humbled by my experience in Japan–by the people, the culture, the natural beauty and the history.
My heart has been aching at the news coverage following the earthquake, tsunami and unfolding nuclear disaster in Japan, and if there is any generosity I can show the people of Japan, I will show it, whatever skeptics might say.
