Also, you have said that Dokdo is a territory of Japan.
However it is wrong. Dokdo was Korea's territory
since Silla. Even though we have promised to use
East Sea and Sea of Japan together, Japan does not
fulfill the promise. 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.
