Hello. This is Songeun Lee, member of Dokdo Cyber Press of South Korea. I contacted to you because of the ‘nihonkai, Japan sea' mark in your post.

It seems unreasonable to use it because it was made in the period of imperialism. Its original name is "East sea" which has been used throughout history.

I really appreciate to you provide various information, but I think the mark of ‘Nihonkai’ must be changed. It would be very grateful if you consider changing it. Thank you.
