Anand Mehta, who lives four stops out of Kamakura on the Enoden Line, quotes his hero when called to ask when we might meet: "Gandhi said, 'What can be done tomorrow can be done today. What can be done today can be done right now.' So, jump on the train."

Several years ago, Mehta declined to be interviewed. Now he has changed his mind. Because, as he explains, the state of the world is more important than he is.

"I want people to know that I am here, that they can come to buy our products and talk about nutrition, that I am willing to go and talk to schools, organizations, anyone interested in health, food and ecology."
