The volume of the stir-fried Jew's-ear is probably the biggest dish in Tokyo. The Chinese letters are 木耳(tree-ear). The Japanese word is Ki-kurage (tree-jellyfish).
Only the Chinese, the Korean and the Japanese eat Jew's-ear. And only Chinese and Japanese eat jellyfish. No people have it in the Philippines. So jellyfish food culture have a root around the Taiwan Island, I think. And Japanese don't like eating ears of something. So they named it plant-jellyfish.
