In the picture of world map that you have used to express the
East Sea, there was only a word Sea of Japan. We do not
insist that you should only express the sea as East Sea. We
would like to ask you to express the sea as two kinds of word.
Japan says that, everyone had expressed sea as Sea of Japan
for a long time, so it would be unconfortable. But if you write as
two of all, it would be more confortable to show it. Today, our
society is living together. We should know how to concede
others and communicate with each other.
