What makes Japanese cuisine the best cuisine in the world?

I was watching Martha Stewart's show off her website, and she did a show entitled Food Around The World. During a Q&A segment, an audience member asked her which food/cooking influenced her the most. And Martha said it wasn't so much influence, as it was that she loves eating Japanese food. She said whether it's cooked, raw or semi-cooked, Japanese cuisine is the best in the world. Is Martha correct?
